plate tetonics

mid ocean ridge

An undersea mountain chain were new ocean floor is produced a divergent plate boundary under the ocean

sea floor spreading

The process by which molten adds new oceanic crust to the ocean floor

Subduction

The process which oceanic sinks beneath a deep ocean trench and back into the mantle at a convergent plate boundary

ocean trench

an undersea valley that represents one of the deepest part of the ocean

Hypothesis

a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

divergent boundary

A plate boundary where two plates move away from each other.

convergent boundary

plate boundary where two plates move toward

Tranform Boundary

A plate boundary where two plates move past each other in opposite directions

stress

A force, the acts rock to change its shape or volume

tension

Stress stash trenches rock show that a big comes thinner in the middle

Comperession

stress, the squeezes rock until it folds or break

shearing

Stretch step pushes masses of Brock in opposite direction in a sideways movement

fault

A break in earths crust, along which rock move or rock beneath the earth surface

earthquake

The measurement of an Earthquake strength based on the semantic wave on and movement along,

Tsunami

A giant wave usually caused by an earthquake beneath the earths ocean floor

scale

volcano

A weak spot in the crust where magma has come to the surface

magma

A molten mixture of rock forming sentences gases in water from the mantle

lava

Liquid magma that reaches its surface

hot spot

An area where magma from deep within the mantle melts through the crust above

extinct

Term used to describe a volcano that is no longer active an unlikely to irrupt again

dormant
