Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates collide, leading to the formation of mountains, trenches, and volcanic activity.

Front

What geologic feature is commonly formed at a convergent boundary between continental crusts?

Back

Mountains are commonly formed at convergent boundaries between two pieces of continental crust.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move apart, leading to the creation of new lithosphere, such as mid-ocean ridges.

Front

What geologic feature is typically found at a divergent boundary between oceanic crusts?

Back

A Mid-Ocean Ridge is typically found at a divergent boundary between two pieces of oceanic crust.

Front

What is a subduction zone?

Back

A subduction zone is formed when one tectonic plate sinks below another, typically occurring at convergent boundaries.

Front

What are transform-fault boundaries?

Back

Transform-fault boundaries are tectonic plate boundaries where two plates slide past each other horizontally, causing earthquakes.

Front

What is the primary process at divergent boundaries?

Back

The primary process at divergent boundaries is the creation of new lithosphere as tectonic plates pull apart.

Front

What features are associated with convergent boundaries?

Back

Convergent boundaries are associated with features such as trenches, volcanoes, and mountain ranges.

Front

What happens at a transform boundary?

Back

At a transform boundary, tectonic plates slide past each other, which can lead to earthquakes.

Front

What is the significance of mid-ocean ridges?

Back

Mid-ocean ridges are significant as they are sites of new oceanic crust formation and are associated with volcanic activity.
