Earth's solid rocky surface

THE THOUGHT THAT ROCKS FORM FLAT HORIZONTAL LAYERS 

THE IDEA THAT A SUPERCONTINENT SPLIT APART INTO PEICES AND SPREAD

the thought that new crust is forming at ridges in the sea floor 

HOT MOLTEN ROCK BENEATH THE EARTH'S SURFACE

The theory that the Earth's surface is broken into many plates that move 

the layer beneath Earth's surface

when the heavier plate slides under the lighter plate when they collide

a big crack in the Earth's crust where motion might show

the place where an earthquake starts

a vibration that goes out when an earthquake happens

the point of ground above the focus

the shaking of Earth's crust after the initial shock 

a device that detects the movement of the crust during an earthquake

the amount of energy released by an earthquake

the opening in a volcano in which  magma might escape

magma that reaches Earth's surface and flows out a vent

a cuplike hollow that forms at the top of volcanoes at the vent

a hot part of the Earth's mantle where magma can melt through a plate 

A STEEP SIDED CONE THAT FORMS FROM HOT ROCKS, RANGING FROM PARTICLES TO BOULDERS

A WIDE GENTLY SLOPED CONE THAT FORMS FROM FLOWS OF LAVA

A CONE FORMED FROM EXPLOSIVE ERUPTIONS OF HOT ROCK AND LAVA

HEAT FROM BELOW EARTH'S SURFACE
