Plate Tectonics

it states the earth’s outer shell is made up of 20 plates moving over a layer of hot rock

• Plate tectonics theory

• Continental draft

• Wegner's 101

• Plated faults

• There are three main forces responsible for mountain building, they are: Volcanism, Faulting and

What kind of movement causes a volcano to occur between two continent plates.

• Volcano

• Convergent

• Divergent

• Valleys

Draw what movement occurs two plates diverge

Choose the best description for what occurs when two oceanic plates converge into one another

• They bump into each other and create an earth, which result in a tsunami

• The older/denser oceanic plates goes below the lighter oceanic plate to create an island

• They cause a shift in the earth's rotation and create a gigantic volcano between them

• The older/denser oceanic plate goes on top of the lighter plate resulting in a mountain range

.....are formed by horizontal compression (squeezing together) of rock layers. as continents come together causing the rock layers to buckle and fold.

What movement occurs when tsunamis occur

• divergent

• convergent

• translantic

• transform

Faulting is when 2 plates move apart and create BLANK or BLANK when a crust is squeezed in between them.

• valley or mountain block

• ocean or volcano

• island or mountain block

• valley or mountain range

Faulting occurs when

• the crust of the earth is broken up by a giant volcano.

• the crust of the earth shifts according to folding.

• the crust falls into the oceanic plate.

• the crust cracks where two plates meet.
