Earth's rocky surface

rocks form flat horizontal layers

supercontinent split into pieces

new crust  is forming on the seafloor 

molten rock below Earth's surface

Earth's surface is broken into plates that float on the mantle

layer beneath the ctust

an ocean plate under another while they collide

a crack in the crust below the surface may move

where an earthquake starts

vibrations that go away from the focus

the point above the focus

more shaking after the earthquake

detects the Earth's movement

the amount of energy let out of the earthquake

the opening of the volcano

magma that comes from the mantle

a bowl like hollow on the top of the volcano

hotter spot of the mantle; melts through a plate

steep sided cone like volccano

wide gentle cone like volcano

explosive volcano then gental

heat from the mantle
