Tectonic plates
The large pieces the crust is broken up into.
Magma
Red-hot molten material — lava that is still in the Earth.
What magma does:
Causes plates to move around.
Converging tectonic plates
Plates that are pushing into each other; creates mountains.
Diverging tectonic plates
Plates that are pulling away from each other; creating new land through drying magma.
Transform boundaries
Two plates slide past each other.
Earthquakes
Caused when plates move significantly.
Volcanic mountain
A mountain formed when molten rock, ash, and gases erupt from beneath the Earth’s surface and build up over time.
Fold mountain
A mountain formed when layers of the Earth’s crust are pushed together and forced upward by tectonic plate movement.
Block mountain
A mountain formed when large sections of the Earth’s crust crack and are pushed upward between fault lines.
