Front

What causes plates to move apart at divergent plate boundaries?

Back

Slab pull, Ridge push, and Convection currents all contribute to the movement of plates at divergent boundaries.

Front

Define a divergent plate boundary.

Back

A divergent plate boundary is where two tectonic plates move away from each other, often resulting in the formation of new oceanic crust.

Front

What is a transform fault?

Back

A transform fault is a type of fault where two tectonic plates slide past each other horizontally.

Front

What is slab pull?

Back

Slab pull is a geological process that occurs at convergent boundaries, where a denser oceanic plate sinks beneath a lighter continental plate, pulling the rest of the plate along.

What is ridge push?

Back

Ridge push is a tectonic process that occurs at mid-ocean ridges, where the elevated position of the ridge causes the plates to slide away from the ridge.
