Surface Features and 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, leading to the formation of new crust as magma rises to the surface.

Where is most new crust formed?

Back

Most new crust is formed at divergent boundaries.

What is the Ring of Fire?

Back

The Ring of Fire is a region around the Pacific Ocean characterized by a high frequency of earthquakes and volcanic activity.

What happens at a convergent boundary?

Back

At a convergent boundary, two tectonic plates collide, which can result in subduction, mountain formation, or earthquakes.

What is oceanic crust?

Back

Oceanic crust is the part of Earth's crust that underlies the ocean basins, typically thinner and denser than continental crust.

Front

How does the age of oceanic crust change with distance from a mid-ocean ridge?

Back

The oceanic crust is younger near the mid-ocean ridge and becomes older as you move away from the ridge.

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

What is the primary process occurring at divergent plate boundaries?

Back

The primary process at divergent plate boundaries is the formation of new crust as magma rises to the surface.

What evidence supports the sinking of the Nazca Plate beneath the South American Plate?

Back

Density data supports the claim that the Nazca Plate is sinking beneath the South American Plate.

What are transform boundaries?

Back

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