The History of Earth

Us humans have been on Earth for over 6 million years and counting. Earth was formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. Scientists believe there has been life on Earth for 4 billion years. Earth has about a 3,595 mile radius. We have water in a liquid at the surface and have many evolving life forms. Those are just some of the reasons you should visit planet Earth.

Planet Earth

On Earth there are 4 seasons, spring, summer, fall, and winter. These seasons occur because of the unique way the Earth orbits around the Sun. It takes Earth 24 hours to make a complete rotation of its axis. it takes Earth 365 days to make a complete revolution around the sun. So 24 hours=1 day and 365 days=1 year. Nuclear fusion is a way we get energy to the Earth and it comes from the Sun. Its a reaction where two atomic nuclei fuse together to create one large nucleus and in the process releases energy. We also have light years which shows how far light travels in a year. Gravity keeps us on the ground, it is a force that attracts our body towards the center of the Earth. On Earth there are many different regions. You may need sunglasses for the hotter regions but you might want to bundle up if you travel to the polar regions.
