Plate Boundaries

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust, such as at mid-ocean ridges.

Front

What geologic feature is commonly found at a divergent boundary between oceanic crust?

Back

Mid-Ocean Ridge.

Front

What geologic feature is commonly found at a divergent boundary between continental crust?

Back

Rift Valley.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move towards each other, often leading to one plate being forced below another, creating subduction zones.

Front

What is a subduction zone?

Back

A subduction zone is an area where one tectonic plate sinks below another, typically occurring at convergent boundaries.

Front

What geologic feature is commonly found at a convergent boundary?

Back

Mountains or volcanic arcs.

Front

What is a transform boundary?

Back

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

Front

What geologic event is most likely to occur at a transform boundary?

Back

Earthquakes.

Front

What is the main difference between oceanic and continental crust?

Back

Oceanic crust is denser and thinner than continental crust, which is thicker and less dense.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates move apart, leading to the formation of new crust as magma rises to the surface.
