8.9AB Plate Tectonics

Front

What is a transform plate boundary?

Back

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

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates push toward each other, often forming mountains or causing one plate to subduct beneath another.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, leading to the formation of new crust, such as mid-ocean ridges.

Front

What geological feature is formed at a convergent boundary?

Back

Mountain ranges are commonly formed at convergent boundaries due to the collision of tectonic plates.

Front

Where is volcanic activity most likely to occur?

Back

Volcanic activity is most likely to occur at convergent boundaries and divergent boundaries, particularly at subduction zones and mid-ocean ridges.

Front

What happens when tectonic plates collide?

Back

When tectonic plates collide, one plate may be forced below the other, leading to subduction and the potential formation of volcanic islands.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by the upwelling of magma at divergent plate boundaries.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle.

Front

What are volcanic islands?

Back

Volcanic islands are landforms created by volcanic activity, often found at convergent boundaries where one plate subducts beneath another.

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 due to tectonic plate movements.
