Rift valley
What do matching mountain ranges on different continents suggest?
The continents were once connected

Continent shapes fit together like puzzle pieces
Fossils of the same plants/dinosaurs were found on different continents
Seafloor spreading is what caused the movement of continents to occur to due to new crust being formed
Which layer causes tectonic plates to move due to magma from the convection process?
The mantle

Divergent boundary
What is the process called when new crust forms on the ocean floor?
Seafloor spreading
