magma
The melted rock below the earth surface when it reaches the surface it is called lava
earthquake
The violent shaking of earths crust as build up energy is released
fold mountains

fault block mountains
mountains that form along a fault line square blocks of rock fall are thrust up or slide
erosion mountains
mountains that are formed entirely by the destructive force of erosion
Focus
The point undergrounds where is the faulting in an earthquake takes place
epicenter
The point on the earth surface directly above the force of an earthquake
faults
A crack on the earth crust along which movement takes place
dome mountains
mountains that form when the magma pushes up on earth colors but does not break through
