earth's rocky and solid surface

the idea that many kinds of rock form flat, horizontality lays

idea that a supercontinent split apart into pieces

new crust is forming at ridges in the sea floor

hot, molten rock below earth crust

earths surface is broken into plates

the layer beneath earths crust

sliding of a denser ocean plate under another plate when they collide

huge crack in earth's crust

the point where an earthquake starts

vibration that spreads out away from a focus

the center of an earthquake right on top the focus

the movement after an earthquake

a device that measures earthquakes

the amount of energy released by a volcano

the central opening in a volcanic area though which magma may escape

magma that reaches earths surface

the top of a volcano that dips in

very hot part of the suns mantle

a steep-side cne that forms from explsive

a cone formed from explosive eruptions

heat from below earths surface
