Earth's solid rocky surface

The idea that rocks form flat horizontal layers

The idea that a supercontinent split apart

The idea that new crust is forming in the sea floor

Hot, molten rock

The idea the surface of Earth is in pieces

The layer beneath the earth's crust

the sliding of an ocean plate sliding under another plate

A crack in the earth's crust

The point where an earthquake starts

A vibration moving away from the focus

The point on earth's surface above the epicenter

shaking of the earth's surface after the earthquake

A device that detects the surface shaking

the amount of energy released by an Earthquake

the central opening in a volcanic area

magma that reaches earth's surface

a cuplike hollow that forms on the top of a volcano

A hot part of the Sun's mantle

A steep-sided cone that forms from explosive eruptions

A gently sloped cone formed from flowing lava

A cone formed from eruptions and flowing lava

Heat from below the earth's surface
