Activity 9 - The Primitive Earth and Moon

Summary:A spectacular journey back in time to witness a massive collision of a planet with earth and the reformation of a new earth, and our moon.
Description:Journey back four billion years to a time when Earth had no moon and was a big volcanic ball of hot rock and primitive ocean. Witness the collision of Earth with another planet called Theia, breaking both worlds into pieces that splatter into orbit forming a huge ring of hot rubble. Fly through the ring and over time, watch as gravity reshapes that debris into a new Earth … and our moon.
