This crash caused several tons of debris to fly off of Earth and Theia, creating an orbit of debris going around the Earth. This debris accreted and formed the Moon.]]> 2021-03-23 16:15:33 UTC https://padlet.com/20941611/5zspx25aslfsbhtw/wish/1343810717 20941611 https://padlet.com/20941611/5zspx25aslfsbhtw/wish/1343839273 Over millions of years the Earth's lava slowly cooled down into a cooler crust instead of its previous lava coated surface.]]> 2021-03-23 16:20:14 UTC https://padlet.com/20941611/5zspx25aslfsbhtw/wish/1343839273 20941611 https://padlet.com/20941611/5zspx25aslfsbhtw/wish/1343862368 The heavy bombardment was a period of time when a series of smaller failed planets and asteroids slammed into Earth.
