Earth where we stand is planet third of the sun as well as the only planet inhabited by humans. It is estimated that Earth has existed for billions of years.
Launching from National Geographic Kids, here are 9 facts about Earth all you need to know!
1) Earth is the third planet from the sun in the solar system. The name Earth comes from Old English and Germanic words meaning ‘land’.
2) Scientists calculate that the Earth is about 4.5 billion years old.
3) Like other planets, Earth also orbits around the sun at a speed of about 30 kilometers per second. It takes 1 year (365 days) to complete one full orbit.
4) Not only enlarges space, the Earth also rotates on its axis which results in day and night. As the Earth rotates, the side facing the sun receives light and the other side in darkness.
5) People often think of the Earth as a giant ball. However, in fact, the shape of the Earth is more like a flattened ball that protrudes at the Equator or an imaginary line around the center of the planet, precisely between the North and South Poles.
6) The protruding part of the Earth is caused by the rotation of the earth as well as the effects of gravity. Gravity is an invisible force that is able to attract objects to each other, which is then this force that pulls objects towards Earth and stops us from floating into space.
7) Earth’s diameter is 12,800 kilometers, making Earth the fifth largest planet in the Solar system after Jupiter, Saturn, Uranus, and Neptune.
8) Earth is the only planet that supports life in the Solar system. This is because the earth has two important things that living things need to survive, sure a lot of oxygen and water. The distance to the sun is also not too hot and not too cold to support life.
9) Earth’s atmosphere is important in sustaining life. The atmosphere protects the Earth from the strong rays of the sun. At the same time, the atmosphere also helps keep the Earth’s temperature comfortable and immediately protects us from meteors.
