• All of the continents are still connected

Pangaea was

• The seafloor moving

What is sea - flooring spreading?

• Watching animals move their habitats

• Mantle is pushed up at the mid-ocean ridge

• Is when the earth heat up

• Climate change

• There was same fossils found on different continents which are far apart

What happens when an oceanic plate (ocean ) collides with continental plates (land)?

• The oceanic plates subduct (goes underneath)

• The continental plate breaks
