Identifying Plate Boundaries

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath the other, leading to subduction, mountain formation, or earthquakes.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, allowing magma to rise and create new crust, often resulting in mid-ocean ridges.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, which can cause earthquakes along faults.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often occurring at convergent boundaries.

Front

What geological features are commonly associated with convergent boundaries?

Back

Common features include mountain ranges, deep ocean trenches, and volcanic arcs.

Front

What geological features are commonly associated with divergent boundaries?

Back

Common features include mid-ocean ridges, rift valleys, and volcanic activity.

Front

What geological features are commonly associated with transform boundaries?

Back

Common features include fault lines and earthquakes.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur, primarily due to tectonic plate boundaries.

Front

How do plate boundaries affect earthquakes?

Back

Earthquakes often occur at plate boundaries due to the movement and interaction of tectonic plates, especially at transform and convergent boundaries.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner, primarily composed of basalt, while continental plates are thicker and less dense, primarily composed of granite.
