Identifying Plate Boundaries

Front

What is a convergent boundary?

Back

A convergent boundary is a type of plate boundary where two tectonic plates move towards each other, often resulting in one plate being forced below the other, leading to subduction.

Front

What is a divergent boundary?

Back

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

Front

What is a transform boundary?

Back

A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally, causing friction and earthquakes.

Front

What happens at a subduction zone?

Back

At a subduction zone, one tectonic plate is forced under another, leading to volcanic activity and the formation of mountain ranges.

Front

What is the main feature of a divergent boundary?

Back

The main feature of a divergent boundary is the formation of new crust as tectonic plates pull apart, often creating mid-ocean ridges.

Front

What geological activity is associated with transform boundaries?

Back

Transform boundaries are associated with earthquakes due to the friction between sliding plates.

Front

Give an example of a convergent boundary.

Back

An example of a convergent boundary is the boundary between the Pacific Plate and the North American Plate, where the Pacific Plate is subducting.

Front

What is the significance of mid-ocean ridges?

Back

Mid-ocean ridges are significant as they are the sites of new oceanic crust formation at divergent boundaries.

Front

How do divergent boundaries affect oceanic crust?

Back

Divergent boundaries lead to the creation of new oceanic crust as magma rises to the surface and solidifies.

Front

What is the role of tectonic plates in earthquakes?

Back

Tectonic plates play a crucial role in earthquakes as their movement and interaction at boundaries can cause stress to build up and release suddenly.
