8.9B Plate Tectonics Mini Flashcard #3

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move toward each other, often resulting in one plate being forced below the other, leading to geological phenomena such as earthquakes and volcanic activity.

Front

What is an example of a convergent plate boundary?

Back

Nazca Plate - South American Plate.

Front

What phenomenon do scientists study at plate boundaries?

Back

Scientists study phenomena such as earthquakes and volcanic eruptions that occur due to the movement of tectonic plates.

Front

What type of plate boundary results in the formation of mid-ocean ridges?

Back

Divergent plate boundaries.

Front

What happens at a divergent plate boundary?

Back

At a divergent plate boundary, tectonic plates move away from each other, leading to the formation of new oceanic crust and 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, often causing earthquakes.

Front

What is the main result of the interaction between tectonic plates at a transform boundary?

Back

Frequent earthquakes.

Front

What geological feature is formed by the collision of the Indo-Australian Plate and the Eurasian Plate?

Back

The Himalayan Mountain Chain.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another, often leading to volcanic activity and the formation of deep ocean trenches.

Front

What is the primary cause of earthquakes?

Back

Earthquakes are primarily caused by the movement of tectonic plates along faults.
