BOOM! Scientist believe the universe started with a big explosion of a big star in space, called the Big Bang. This was followed by allot of collisions.
How Earth started
How Earth started
About 15 billion years ago the whole universe was in a tiny bubble. The bubble began heating up making energy until it exploded into tiny particles. This was called the Big Bang.
The Particles
The Particles
First the tiny particles clumped together making larger particles. The wind swept away the lighter particles like gasses. Then the heavy rock like particles began to form earth.
Next gravity pulled the particles down creating Earth's core. Lastly, the other particles layered on top of each other to form the rest of Earth's layers. In conclusion, that is how the earth was formed.
This is an artist's drawing of the Big Bang (the explosion that started the universe).
This is a satellite going around Earth.
This is the Earth seen from space.
This diagram shows the Earth's layers. The core is at the center.
