In Ms. Shaw class we studied about here are some things that I learn.Earth is the third planet from the sun . Earth's mantle is 1,800 miles thick and 6,700 degrees. Scientist's think Earth was made 4.6 billion years ago. Earth's crust is very thin. I think living on Earth is great. I learned lots of things about Earth that I didn't knew.
Do you now other things about Earth?
