Plate Boundaries Review

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges or rift valleys.

Front

What geologic feature is commonly found at a divergent boundary?

Back

Rift Valley.

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally, leading to earthquakes.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move towards each other, often resulting in one plate being forced beneath another, creating mountains or volcanic activity.

Front

What geologic feature is commonly found at a convergent boundary?

Back

Mountain ranges or volcanic arcs.

Front

What occurs at a divergent boundary between two oceanic plates?

Back

Sea floor spreading.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is created at mid-ocean ridges as tectonic plates pull apart.

Front

What is the significance of the mid-ocean ridge?

Back

The mid-ocean ridge is a continuous mountain range formed by plate tectonics, marking the site of sea floor spreading.

Front

What happens at a transform boundary?

Back

At a transform boundary, two tectonic plates slide past each other, which can cause earthquakes.

Front

What is an example of a transform boundary?

Back

The San Andreas Fault in California.
