Pieces of the lithosphere are in slow constant motion.

The flow that transfers heat through a fluid.

The pull of gravity on a plate that is being subducted.

New crust pushes old crust out of way as older, denser crust is pulled by gravity.

Plates move apart

Land form that results from a divergent plate boundary. Great Rift Valley.

Underwater landform that is caused by a divergent plate boundary. Mid-Atlantic Ridge

Plates move together

Ocean vs. Continent. Chile Peru Deep Sea Trench with Andes Mountains.

Ocean vs. Ocean. Mariana Trench.

Continent vs. Continent. Himalaya Mountains.

Where two lithospheric plates come together and over-lap

Where the lithosphere is subducted back into the asthenosphere

The Aleutian Trench

Plates slide past each other

Resulting event of Transform Boundary

Resulting from transform boundaries. San Andreas Fault.

Places within the mantle where rocks melt to generate magma.

Hawaiian Islands are the tops of gigantic volcanic mountains.

Volcanic activity in center tectonic plates; not related to plate boundaries/movements.

The younger islands of Hawaii have the most active volcanoes.
