Plate Motion Review

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often resulting in the formation of mountains or volcanic activity.

Front

What geological feature is commonly found at a convergent boundary between a continental and oceanic plate?

Back

Volcanoes are commonly found at this type of boundary due to the subduction of the oceanic plate.

Front

Define subduction.

Back

Subduction is the process where one tectonic plate sinks beneath another, typically occurring at convergent boundaries.

Front

What occurs at a divergent boundary?

Back

At a divergent boundary, tectonic plates move away from each other, leading to the formation of new crust, such as at mid-ocean ridges.

Front

What is the Mid-Atlantic Ridge?

Back

The Mid-Atlantic Ridge is a divergent plate boundary where the Eurasian and North American plates are moving apart, creating new oceanic crust.

Front

What type of boundary is associated with earthquakes?

Back

Transform boundaries are associated with earthquakes, as plates slide past each other, causing stress and friction.

Front

What happens to oceanic crust at a subduction zone?

Back

Denser oceanic crust sinks beneath lighter continental crust at a subduction zone.

Front

What is a transform boundary?

Back

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

Front

What is the Ring of Fire?

Back

The Ring of Fire is a region around the Pacific Ocean known for its high volcanic and seismic activity, primarily due to subduction zones.

Front

What is the result of plate tectonics?

Back

Plate tectonics results in various geological phenomena, including earthquakes, volcanic eruptions, mountain building, and ocean trench formation.
