What type of boundary creates trenches and deep underwater canyons?

Convergent Boundary, Subduction Zone

Front

Describe a convergent boundary.

Back

A convergent boundary is where two tectonic plates move toward one another, causing crumpling of continental plates to form mountains or subduction of oceanic plates, leading to earthquakes and volcanoes.

What happens at a subduction zone?

Back

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

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, causing earthquakes when they get stuck.

What geological features are formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys are formed at divergent boundaries.

Front

What is the main cause of earthquakes at transform boundaries?

Back

Earthquakes occur when the plates get stuck and then suddenly slip, releasing energy.

What is the difference between oceanic and continental crust?

Back

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

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean where many earthquakes and volcanic eruptions occur due to tectonic plate movements.

What is a fault line?

Back

A fault line is a fracture in the Earth's crust where blocks of land have moved past each other.
