Earth Is The Only Planet Essay

There’s no place like home. Home has your room for you to sleep in, it has food for you to eat, and you have your family to surround yourself with. Just like that, Earth has all the necessities for us to survive on. It has water for us to drink, air for us to breathe, and terrain for us to live on. Unlike other planets, Earth is the only planet whose name does not come from Greek or Roman Mythology. Its German name is Erde, which means dirt or ground. More than two-thirds of the Earth is covered in water. Earth is the third planet from the sun and is the biggest of the inner rocky planets. In the end, Earth has everything we need to live and is the only planet to have known to support life..

The formation of Earth all started with a cloud of dust and gas drifting in space about 4,600 million years ago. Bacteria and blue-green algae were the first known forms of life but only seemed to appear 3,500 million years ago. More plants and animals species came about 570 million years ago and evolved from then on. Some have succeeded on till today but others including the dinosaurs. The seven continents neared their present locations roughly about 50 million years ago, but still however drift very slowly over our planet’s surface. The mountain ranges including the Himalayas began to form 40 million years ago, which are still contentiously being built up and worn away.

The planet Earth is consists of four layers on the inside. At the very center is the inner core. According to scientists, the inner core is supposedly a hot ball of solid iron and nickel, with temperatures as hot as up to 11,000F. It’s with all of the massive weight pressing around the inner core it is thought to be a solid. Right outside of the inne...

... water moves around the Earth causing our weather. The average weather in an area during a long period of time is climate.

Earth has three major climate zones. There are the cold polar regions, the hot humid tropics near the equator, and the warm temperature areas in between. The climate zones can be even more divided using other things that affect the temperature, such as the height of the land and the distance from the mountains or sea. The higher the land, the temperature is lower, while the ocean keeps coastal areas warmer in the winter and cooler in the summer.

220 million years ago all of the continents were joined making one huge continent called Pangea, meaning “all Earth.” It was at about 110 million years ago the continents started to split apart. The dinosaurs still conquered the Earth, but more mammals and the first birds had started to appear.
