Crust
This is a quick shaking of the ground that happens when stored energy is suddenly let go.

In this game, a small square means the rock has very little of this property.
Less Mass
An opening in the Earth's crust that lets out hot molten rock (magma/lava)
Volcano!
The layer of very hot, thick rock found just below the crust.
Mantle
This word means to break apart or tear, which is what happens to rock when too much force b

Tectonic Plates

Earthquake!
The name for the currents of super-hot rock in the mantle that slowly drag the plates around.
