我们的地球作文我们的地球作文(合集10篇)我们的地球作文1曾经有人给我讲过这样的一个故事，人类第一次蹬上太空，看到地球是一个白蓝相间、透明如洗的水晶球；可是，是隔30年，当人类再一次蹬上太空时，所看到的情景却截然不同。
以往晶莹剃透的地球，如今表面增添了许多灰黑色的气体，可想而知，这就是我们常说的大气污染。
听了这个故事。
我心中如海浪汹涌澎湃。
总有一些感叹在我脑海中浮现。
俗话说：“地球就是我们的家园。
”我们每一个人都应该为了这个家园、为了这片土地，做出自己应进的义务。
可是仍然还有一些人，在不断的滥用化学物，来破坏我们美丽的家―地球。
据统计，在以地球为中心的方远几百万里以内都没有适合人类居住的第二个星球。
所以我们更应该爱护我们的家。
因为我们只有一个地球！从盘古开天辟地以来，到科技飞速发展的现在，以有了悠久的历史。
人类不断声息繁衍，使我们的地球更具有了活力。
可是，在人类声息繁衍的同时地球在逐步面临资源枯竭的危险。
有人说：“资源枯竭了还可以再生。
”可是在泥土下面，蕴藏的资源并不是短时间内可以再生的。
他们必须经过无数次风雨的洗理和地壳的变迁，才能形成。
所以我们人类不能不加截止的开采，应该用自己的爱去呵护每一份资源。
为了地球能更美丽；为了人类更好的声息繁衍；为了花更美，草更绿。
让我们共同携手，用自己的爱，自己的行动，来谱出最美的诗篇吧！我们的地球作文2地球是太阳系中八大行星之一，按离太阳从近到远的顺序排列为第三颗，地球绕着太阳转，月亮绕着地球转。
地球以赤道为界分为两大部分：南半球和北半球，中国位于北半球。
北半球和南半球各有一条重要的线，分别叫北回归线和南回归线，当太阳的轨迹运行到北回归线时，北半球是夏天，南半球是冬天。
当太阳的轨迹运行到南回归线时则正好相反。
地球拥有一个由78%的氮气、21%的氧气和1%混合微量其他包括二氧化碳和水蒸气组成的厚密大气层。
其中浓度相对较高的那部分叫臭氧层，臭氧层是地球表面和太空之间的缓冲，它在地球上空形成一把“保护伞”，将太阳光中99%的紫外线过滤掉，这对地球上生命的生存十分重要！经过人类的探索，发现地球是一个两极稍扁、赤道略鼓的不规则球体。
看看我们的地球排比句
1、看看我们的地球，是我们灵魂的归宿，是植物的根须，是动物的栖息地。
2、看看我们的地球，地球赋予我们智慧，地球赋予我们青春，地球赋予我们情感，地球，是我们大家赖以生存的家园！

小学英语作文《我们的地球》全文共6篇示例，供读者参考篇1Our Planet EarthHello everyone! My name is Emily, and I am a fourth-grade student. Today, I want to talk to you about our amazing planet Earth. It's the only home we have, and it's so beautiful and special.Earth is a big round ball, kind of like a giant sphere. It's mostly covered in water, which we call oceans. The land areas are called continents, and there are seven of them: North America, South America, Europe, Asia, Africa, Australia, and Antarctica. Isn't it incredible that all these different countries and cultures exist on one planet?Our planet is not just a lifeless rock though. It's teeming with life! There are millions of different species of plants and animals that call Earth home. From the tallest trees in the rainforest to the tiniest insects crawling on the ground, our planet is full of amazing creatures.One of the coolest things about Earth is that it has an atmosphere. This is a blanket of gases that surrounds our planet and protects us from the harsh environment of space. The atmosphere is what allows us to breathe and live comfortably on Earth's surface.Earth is also the perfect distance from the sun, which gives us just the right amount of warmth and light. If we were too close to the sun, it would be too hot for life to exist. But if we were too far away, it would be freezing cold. Isn't it amazing how everything is just right for us to live here?One of the biggest challenges we face today is climate change. This is when the Earth's temperature starts to rise because of things like pollution and the burning of fossil fuels. Climate change can lead to melting ice caps, rising sea levels, and more extreme weather events.That's why it's so important for us to take care of our planet. We can do little things like turning off lights when we're not using them, recycling our trash, and planting trees. Every bit helps to keep our Earth healthy and beautiful.There's so much more I could say about our amazing planet, but I'll leave it there for now. Just remember, Earth is our one andonly home, and we need to cherish and protect it. It's a truly special place in the universe, and we're lucky to live here.Thank you for listening, and let's all do our part to make Earth an even better place for generations to come!篇2Our Beautiful EarthHello everyone! My name is Emily and I am going to tell you all about our amazing planet Earth. Earth is the wonderful world we call home and it's truly a special place.First of all, Earth is the only planet we know of that has life. Can you imagine that? Out of all the planets in our solar system and beyond, Earth is the only one with living creatures. We have animals, plants, trees, flowers, and of course, people like you and me! Isn't that incredible? Earth provides the perfect conditions for life to exist with its air, water, temperatures, and so much more. We are very lucky to live here.Earth has some awesome features that make it unique. It has white clouds drifting across the bright blue sky during the day. At night, we can see twinkling stars, a crescent moon, and sometimes even shooting stars! How cool is that? Earth also hastall mountains reaching towards the heavens, vast deserts of golden sand, and frozen lands at the North and South Poles. Our planet has lush green forests full of all kinds of plants and animals too.But that's not all that makes Earth special. We also have huge bodies of water covering almost three-quarters of the planet's surface. The oceans are home to remarkable marine life like whales, dolphins, sharks, coral reefs, and millions of other species. And let's not forget about all the incredible rivers, lakes, and streams winding across the landscapes.Earth's lands are divided into seven continents - North America, South America, Europe, Asia, Africa, Australia, and Antarctica. Each continent has distinct landscapes, climates, and cultures. Some regions are hot and dry while others are freezing cold. There are humid rainforests, mountainous areas, rocky canyons, rolling hills, and so much more. Our planet truly has an incredible variety of environments.And you know what else is amazing about Earth? All the colors! We can see vibrant shades of green, blue, red, yellow, and every other color of the rainbow thanks to the trees, sky, water, flowers, and more. Color makes our world bright and beautiful.While Earth is a wondrous place, we must take care of it. Humans can sometimes damage the environment through pollution, deforestation, and other harmful activities. We all need to do our part to reduce waste, use less plastic, plant more trees, conserve energy and water, and protect wildlife habitats. After all, Earth is the only home we have and we want to keep it healthy for ourselves and future generations.I feel so grateful to live on this beautiful blue and green planet spinning through the cosmos. Earth has given us everything we need to live and thrive. It's important that we appreciate our world and all the marvels it provides - from the tiniest ladybug to the highest mountain peak. There's nowhere else quite like Earth and it will always be my favorite place in the entire universe!篇3Our EarthHave you ever really thought about our amazing planet Earth? It's the only place we know of that has life! Earth is a truly special place in the vastness of space. Let me tell you some awesome things about the world we live on.Earth is a rocky planet, with land masses called continents and huge areas of water called oceans. Around three-quarters of the Earth's surface is covered in oceans! That's a lot of water. The largest ocean is the Pacific Ocean. It covers about one-third of the entire planet! The continents make up the other one-quarter of the Earth's surface. The largest continent is Asia.All of the land, water, and air around us makes up what is called the biosphere. And it's absolutely teeming with life! From the tiniest microbes to the biggest whales, our planet has an incredible diversity of living things. Scientists have identified and named around 1.7 million different species so far, but they estimate there could be tens of millions more waiting to be discovered! Isn't that remarkable?A big reason why Earth is able to sustain life is because of its atmosphere. This blanket of gases surrounds and protects our planet. The atmosphere contains oxygen for us to breathe and other gases that help retain heat from the sun's rays, keeping temperatures mild enough for life. Without our atmosphere, the Earth would be a frozen, lifeless rock drifting through space.Speaking of the sun, it's absolutely vital for life on Earth. Our sun is a star, a huge nuclear furnace pumping out enormous amounts of energy as light and heat. This energy warms ourplanet and allows plants to grow through a process called photosynthesis. Plants are then eaten by animals like us, transferring that stored energy. In this way, the sun's energy powers almost all life!Earth has some amazing natural cycles and systems that help sustain conditions perfect for life. One of those is the water cycle. Water is constantly evaporating, condensing into clouds, precipitating as rain or snow, and then flowing back into oceans, rivers and lakes in an endless loop. This cycling of water is essential for growing our food and supplying us with fresh water to drink.Another incredible system is the carbon cycle. Animals like us breathe in oxygen and exhale carbon dioxide. Plants do the opposite - they take in carbon dioxide and release oxygen! This cycling of gases helps regulate the atmosphere. Sadly, humans have been disrupting this cycle by releasing extra carbon dioxide from burning fossil fuels, which is causing temperatures to rise unnaturally. This is called global warming and it's a big problem we need to fix.Every part of the Earth is interconnected in some way - nothing exists in isolation. The rocks, soil, air, water and living organisms all interact and depend on each other. When one partis disturbed or damaged, it affects everything else. That's why we have to be very careful with how we treat our planet.We really lucked out being born on such an incredible world! Floating through the cold emptiness of space is a lush, nurturing haven absolutely overflowing with beauty, diversity, and the miracle of life. Earth gives us everything we need to survive and thrive. I think it's our responsibility to appreciate and protect this amazing planet we call home.We should feel very fortunate to live on Earth. While it may sometimes seem ordinary to us because it's the only planetwe've known, it is truly extraordinary when you think about it. As Carl Sagan, a famous science educator once said, "The Earth is a very small stage in a vast cosmic arena." Our planet is unique and special. We need to take care of it so that future generations can experience and appreciate its wonders too.篇4Our Amazing EarthPlanet Earth is truly an amazing place! It's the only home we have in this vast universe, and it's full of incredible wonders. From soaring mountains and deep blue oceans to colorful rainbows and twinkling stars, our world is a magical treasure.One of the most fascinating things about Earth is the variety of landscapes and environments. On one part of the globe, you might find freezing glaciers and snow-capped peaks. But if you travel to another region, you could be surrounded by hot, sandy deserts as far as the eye can see. Some areas are covered in lush, green forests while others have wide-open grasslands dotted with wildflowers. How amazing that all these diverse places exist on the same planet!Earth is also bursting with life in countless shapes, sizes, and colors. Animals roam the lands and soar through the skies. Scaly reptiles slither across rocky terrain, while furry creatures bound through grassy fields. And let's not forget the vast oceans, teeming with fish, whales, dolphins, sharks, and so many other marine creatures. From the tallest giraffe to the tiniest insect, our planet's wildlife is truly a marvel.Speaking of oceans, they make up most of Earth's surface. The deep blue waters cover over 70% of the globe! Can you imagine how much water that is? Oceans are home to beautiful coral reefs, mysterious trenches that stretch miles deep, and even underwater volcanoes. On top of the waters, mighty waves crash against sandy shores in a never-ending rhythm. The oceansare both powerful and peaceful, constantly reminding us of nature's grandeur.Up in the sky, our planet's atmosphere puts on a dazzling show from dawn until dusk. At sunrise, the sky is set ablaze in warm shades of red, orange, and pink. As the day goes on, the brilliant blue sky is dotted with puffy white clouds that morph into all kinds of fun shapes. Then as night falls, the velvety darkness comes alive with a glittering tapestry of stars, planets, and galaxies. Sometimes we're even treated to the shimmering beauty of the Northern Lights dancing across the heavens. Our sky is nature's ever-changing canvas!Earth is also home to many fascinating weather patterns. When warm and cold air masses meet, they can create intense thunderstorms with booming claps of thunder and brilliant streaks of lightning. In some regions, powerful tornados form and spin across the landscape. During the winter, icy snowflakes gently drift down to blanket the ground in a soft layer of white. The blazing summer sun beating down can also trigger billowing thunderheads that lead to refreshing rain showers.From the depths of the soil to the highest clouds, Earth is undeniably a place of remarkable beauty. But our planet doesn't just look amazing—it also provides us with all the things we needto survive and thrive. The air we breathe, the water we drink, the food we eat, the materials we use to build our homes...they all come from the precious resources of our world.篇5Our Planet EarthPlanet Earth is the most amazing place! It's the only home we have in this huge universe. The Earth is a beautiful blue and green ball when you look at it from space. The blue parts are the oceans, lakes and rivers. And the green parts are the land with forests, grasslands, farms and cities where people live.I think the Earth is pretty much the best planet there is. Sure, some of the other planets are big and gaseous or have cool rings around them. But Earth is perfect for humans like you and me. It has air for us to breathe, water for us to drink, and soil to grow yummy fruits and vegetables. Earth has everything we need to stay alive and healthy.My favorite part of Earth is all the different kinds of landscapes and environments. I love the sandy beaches by the ocean, with the waves crashing on the shore. I love hiking through forests with tall trees all around. I love looking at amazing photographs of places like the Grand Canyon, MountEverest, the Amazon rainforest, and the African savannas with elephants and giraffes. Planet Earth has so many incredible places to explore!There are also so many cool animals and plants on Earth. We share our planet with millions of different species, from tiny insects to massive whales in the sea. Most of the animals are harmless, but some like lions, tigers, bears, sharks and snakes are dangerous so you have to be careful around them. My favorite animals are dogs, cats, elephants, and monkeys. What's your favorite animal?s have been living on planet Earth for thousands and thousands of years. Our ancestors used to live in caves and hunt animals with spears and bows and arrows. But humans are very clever and invented all sorts of tools, machines, buildings, transportation and technology to make our lives better. Nowadays we have cars, planes, computers, phones, televisions, air conditioning and so much more. We even have rockets that can fly people and robots to the Moon and other planets to explore space!Even though humans have built up amazing cities and technologies, we can't forget that planet Earth gives us everything we need to survive. The Earth provides our food, air, water, soil, energy and resources. If something bad happened tothe Earth, it would be terrible for all humans and animals. That's why we need to take really good care of our planet.One big problem facing the Earth is pollution. Humans create a lot of trash and waste that gets thrown into the rivers, oceans and lands. We also burn a lot of fossil fuels like oil, gas and coal which pollutes the air and causes global warming. All this pollution is bad for the environment and can harm plants, animals and people.To take better care of the Earth, we need to reduce pollution by recycling, conserving energy and resources, switching to renewable clean energy, and protecting wildlife habitats. We also need to stop deforestation which is cutting down too many trees. Trees are important because they absorb carbon dioxide and produce the oxygen we need to breathe. Protecting the Earth's rainforests is crucial.If everybody did their part to be more eco-friendly, we could make the Earth a cleaner and greener place for all. Things like using less plastic, driving or flying less, eating less meat which takes a lot of energy to produce, and planting more trees can really help the environment.Another big issue facing the Earth is that our climate is changing due to human activities putting too much carbondioxide into the atmosphere. Climate change is making the whole planet warmer overall, causing sea levels to rise, deserts to expand, weather to become more extreme, and putting many species at risk of going extinct. Coastal cities could end up flooded if sea levels keep rising.To stop climate change from getting worse, countries need to work together to cut down on burning coal, oil and gas which creates greenhouse gas emissions. We need a big global effort to develop and use more renewable energy sources like solar, wind, hydroelectric and nuclear power instead of fossil fuels.I really hope humans can solve these big environmental problems like pollution and climate change so the Earth stays healthy for my future children and grandchildren. Our planet is an incredible life-supporting marvel and we need to protect it. Maybe one day humans will even be able to make other planets like Mars habitable too! But for now and forever, Earth is our one and only true home in the universe. We're all part of the Earth's environment and we need to be good planetary residents. Earth is simply the best! Let's all work hard to take great care of our amazing planet.篇6Our Amazing EarthHi there! My name is Emma and I'm going to tell you all about our incredible planet Earth. Get ready to learn some super cool facts about the place we call home!The Earth is a giant sphere or ball that floats through the blackness of space. From far away it looks like a beautiful blue marble against the dark backdrop of the universe. That's because over 70% of the Earth's surface is covered by oceans, seas and other bodies of water. The rest is land made up of continents and islands.The Earth is the third planet from the Sun in our Solar System. It's just the right distance away so that it's not too hot or too cold for life to exist. In fact, the Earth is the only planet we know of so far that has living things! The Moon is Earth's only natural satellite that orbits or circles around it. At night when the sky is clear you can see the Moon shining brightly.Our planet is made up of several different layers. The outer layer that we live on is called the crust. Underneath that is the mantle, then the outer core and inner core at the very center. The crust and upper mantle form the land areas we call continents and the floors of the oceans. These pieces of crust are constantly moving tiny amounts in different directions due to the motionsof the mantle below. This movement is what causes earthquakes, volcanoes and the formation of mountains.Speaking of mountains, some of the tallest ones on Earth are the Himalayas in Asia. The highest peak is Mount Everest at over 29,000 feet! On the opposite end, the deepest areas are the Mariana Trench in the Pacific Ocean. It plunges down almost 7 miles under the sea! There are all sorts of incredible geographic features across the globe like deserts, canyons, waterfalls, glaciers and more. Our world is full of amazing natural wonders.Planet Earth is home to millions of different species of plants and animals. There are vast forests, jungles full of exotic creatures, fish and marine life in the oceans, and species adapted to every type of environment. Humans are just one of the many life forms that depend on Earth's perfect conditions to survive. We need to take care of our planet and all its inhabitants.The air we breathe is made up of different gases like nitrogen, oxygen, carbon dioxide and others. This mixture of gases is called the atmosphere and it surrounds the entire planet. The atmosphere protects us from the Sun's harmful rays and extreme temperatures in space. Clouds form from water vapor in the atmosphere which returns to Earth as precipitation like rain, snow, hail or sleet. This water cycle is essential for life.In addition to the atmosphere, the Earth has a magnetic field that acts like a giant force field. It shields us from cosmic radiation and charged particles from the Sun that would otherwise be very dangerous. This magnetic field is caused by the churning of the planet's molten metal outer core.Our Earth is in a constant state of change over long periods of time. The surface is slowly being reshaped by wind, rain, ice and even living creatures. Tectonic plates under the crust gradually move and shift positions which can cause new mountain ranges to form or old ones to be worn down over millions of years. This process is part of the rock cycle that continually creates and sculpts the landscape of our planet.Every 24 hours, the Earth spins or rotates once on its axis. This rotation causes the cycle of day and night as the side facing the Sun experiences daylight while the other side is in night. Every 365 days, the Earth completes one full revolution or orbit around the Sun, giving us the cycle of seasons.s have only explored a tiny fraction of our vast planet so far. There are still many places yet to be discovered both on land and in the ocean depths. Even with all our advanced technology, we still have so much more to learn about how Earth formed, its inner workings,and the history of life here. Our home is an amazing and mysterious world!There are countless other fascinating details about the Earth that I could go on and on about. But for now I'll leave you with this thought - the next time you feel the warm sunshine, breathe in the fresh air, or marvel at a bright star at night, remember that you are a tiny but important part of our incredible, life-sustaining planet. We're all in this together onboard Spaceship Earth!。
