What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often resulting in the formation of ocean trenches and volcanic mountains.

Front

What crustal feature is formed at a divergent boundary in the ocean?

Back

A Mid Ocean Ridge is formed at a divergent boundary in the ocean.

Front

How is oceanic lithosphere destroyed?

Back

Oceanic lithosphere is destroyed at convergent boundaries where it is subducted into the mantle.

Front

What is the formula to calculate time when distance and speed are known?

Back

Time = Distance / Speed.

Front

If the Juan de Fuca plate moves at 40mm/yr, how long will it take to move 320mm?

Back

It will take 8 years.

Front

What is a transform fault boundary?

Back

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

Front

What crustal feature is associated with a convergent boundary?

Back

Ocean trenches and volcanic mountains are associated with convergent boundaries.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often found on land.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates move apart, leading to the formation of new crust, such as at mid-ocean ridges.

Front

What is subduction?

Back

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