Alfred Wegener

Alfred Wegner was a German polar researcher, geophysicist, and meteorologist. He was known for his Continential Drift Theory.

Convergent Boundaries

An actively deforming region where two or more tectonic plates or fragments of the lithosphere move toward one another and collide.

Divergent Boundaries

A divergent boundary is a linear feature that exists between two tectonic plates that are moving away from each other.

Tranform Boundary

A place where two plates slide past each other.

These are examples of the three types of boundaries found in Earth's surface.

The Juan De Fuca Plate

The Juan De Fuca plate is a plate that is off the coast of Washington.

Formation of Cascades

All three types of boundaries had a role in the formation and eruptions of the Cascades.

Convection Currents and Tectonic Plates

Convection currents move the plates due to the circular movement of the hot rock underneath, which causes the plates to float on the currents.
