Plate Tectonics Identifying Boundaries

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is a type of tectonic boundary where two tectonic plates move away from each other, leading to the formation of new crust as magma rises to the surface.

Front

What geological features are commonly associated with divergent boundaries?

Back

Geological features commonly associated with divergent boundaries include mid-ocean ridges, rift valleys, and volcanic activity.

Front

What is a transform plate boundary?

Back

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

Front

What are the characteristics of transform boundaries?

Back

Transform boundaries are characterized by lateral movement of plates, the absence of volcanic activity, and frequent earthquakes.

Front

What happens at convergent plate boundaries?

Back

At convergent plate boundaries, two tectonic plates move toward each other, which can result in subduction, mountain building, or volcanic activity.

Front

What is subduction?

Back

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

Front

What type of boundary is formed when two continental plates collide?

Back

When two continental plates collide, a convergent boundary is formed, often resulting in the creation of mountain ranges.

Front

What is the significance of the mid-ocean ridge?

Back

The mid-ocean ridge is a continuous mountain range formed by divergent boundaries, where new oceanic crust is created as tectonic plates pull apart.

Front

How do earthquakes occur at transform boundaries?

Back

Earthquakes occur at transform boundaries due to the build-up of stress as plates slide past each other, which is released suddenly when the plates move.

Front

What is the role of magma in divergent boundaries?

Back

Magma plays a crucial role in divergent boundaries as it rises to fill the gap created by separating plates, leading to the formation of new crust.
