Scientists who studies forces that make and shape earth.
Geologists
The place where two plates move apart.
Divergent boundary.
Three types of stress that act upon rocks changing shape or volume.
Shearing, tension, compression.
Name given to magma once it reaches the surface.
Lava.
Destructive.
Two things that increase by degree the deeper into the earth one measures.
The name Wegener gave the super continent, which means "all lands."
Pangaea
A break in Earth's crust where slabs of crust move past each other.
