PRESENTATION OUTLINE
{Plate Tectonics}
Plate Tectonics is a theory that the earth is divided into several plates.
{Convection Currents}
The flow that transfers heat through a fluid.
{Slab Pull}
The pull of gravity on a plate that is being subducted.
{Ridge Push}
New less dense crust forming at divergent plate boundaries pushes older crust out of the way as older, denser crust gets pulled away by gravity.
{Rift Valley}
An elongated valley formed by the depression of a block of earths crust between two faults.
{Divergent boundary} Plates move away from each other.
{Mid Ocean Ridge}
Underwater landform that is caused by a divergent plate boundary.
{Convergent Boundary}
Two lithospheric plates collide.
Resulting Landform from ocean vs. continent
{Volcanoes}
Resulting landform from ocean vs. ocean
{Island Arc}
Resulting landform from continent vs. continent
{Mountains}
{Subduction Zone}
Collision between 2 of earths plates, where one of the earths plates slide underneath the other and sink into the mantle.
{Deep Ocean Trench}
A steep sided depression in the bottom of the ocean.
{Deep Ocean Trench} -Example-
{Transform Plate Boundary}
When 2 plates slide past each other.
{Result of Transform}{Boundaries}
Earthquakes and other natural
disasters.
