8.9B -- Plate Boundaries -- 8th Grade Science

Front

What is a Divergent Boundary?

Back

A Divergent Boundary is where two tectonic plates move away from each other, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What is a Convergent Boundary?

Back

A Convergent Boundary is where two tectonic plates collide, causing one plate to be forced beneath another, often resulting in the formation of mountains or trenches.

Front

What is a Transform Boundary?

Back

A Transform Boundary is where two tectonic plates slide past each other horizontally, leading to earthquakes along fault lines.

Front

Example of a Divergent Boundary?

Back

Mid-ocean ridges, such as the Mid-Atlantic Ridge.

Front

Example of a Convergent Boundary?

Back

The boundary between the Pacific Plate and the North American Plate, which forms the Aleutian Islands.

Front

Example of a Transform Boundary?

Back

The San Andreas Fault in California.

Front

What geological feature is formed at a Divergent Boundary?

Back

Rift valleys and mid-ocean ridges.

Front

What geological feature is formed at a Convergent Boundary?

Back

Trenches and mountain ranges.

Front

What geological feature is formed at a Transform Boundary?

Back

Fault lines, which can lead to earthquakes.

Front

What happens to the crust at a Divergent Boundary?

Back

New crust is created as magma rises to the surface.
