Types of plate boundaries

Front

What is a subduction zone?

Back

A subduction zone is formed when a more dense tectonic plate sinks below a less dense plate.

Front

What type of plate boundary is the San Andreas fault line?

Back

The San Andreas fault line is a Transform plate boundary.

Front

What happens at divergent plate boundaries?

Back

At divergent plate boundaries, tectonic plates move apart from each other.

Front

What is subduction?

Back

Subduction occurs when a less dense tectonic plate slides under a more dense tectonic plate.

Front

What type of plate boundary is formed when two plates collide?

Back

A convergent plate boundary is formed when two plates collide.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What geological activity is commonly associated with convergent boundaries?

Back

Earthquakes and volcanic activity are commonly associated with convergent boundaries.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.

Front

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.
