200
the point under the surface of the earth where plates fault
What is focus
200
the opening which magma erupts onto the surface

200
rocks that form above ground (volcanic eruptions)
What is extrusive
300
the earths shape slightly wider at the equator due to rotation
What is oblate spheroid
300
the movement of heat though the asthenosphere which causes plates above to move

forms in layers
