Plate Tectonics

Front

What are ocean trenches?

Back

Deep, narrow depressions in the ocean floor formed at oceanic-continental boundaries where one tectonic plate subducts beneath another.

Front

What happens at oceanic-continental boundaries?

Back

The denser oceanic crust subducts under the less dense continental crust, leading to the formation of ocean trenches and volcanic activity.

Front

What is a Continental-Continental Convergent boundary?

Back

A tectonic boundary where two continental plates collide, resulting in the formation of mountains.

Front

What geological forces create mountain ranges?

Back

Converging tectonic plates push against each other, causing the crust to fold and uplift, forming mountains.

Front

What is the relationship between tectonic plates and earthquakes?

Back

Earthquakes occur along the boundaries of tectonic plates due to their movement and interaction.

Front

What are transform boundaries?

Back

Tectonic plate boundaries where plates slide past each other horizontally, often causing earthquakes.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle, often leading to volcanic activity.

Front

What is a divergent boundary?

Back

A tectonic boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

How do volcanic islands form?

Back

Volcanic islands are formed by volcanic activity at oceanic-oceanic convergent boundaries or hotspots.

Front

What is the Pacific Ring of Fire?

Back

A region in the Pacific Ocean basin known for its high levels of seismic activity and volcanoes, due to tectonic plate boundaries.
