Plate Boundaries

Front

What is a Divergent Plate Boundary?

Back

A boundary where two tectonic plates move apart from each other, often resulting in the formation of new crust as magma rises to the surface.

Front

What is a Convergent Plate Boundary?

Back

A boundary where two tectonic plates collide or come together, which can lead to the formation of mountains, earthquakes, or volcanic activity.

Front

What is a Transform Plate Boundary?

Back

A boundary where two tectonic plates slide past each other horizontally, causing friction and earthquakes.

Front

What layer of the Earth allows tectonic plates to move?

Back

The mantle, which is a semi-fluid layer beneath the crust that facilitates the movement of tectonic plates.

Front

How many major tectonic plates are there?

Back

There are 12 major tectonic plates.

Front

What causes the movement of tectonic plates?

Back

The movement is caused by changes in the mantle, including convection currents that transfer heat.

Front

What is the Earth's crust?

Back

The outermost layer of the Earth, which is solid and relatively thin compared to the layers beneath it.

Front

What is the mantle?

Back

The layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What happens at a Divergent Boundary?

Back

At a divergent boundary, tectonic plates move apart, leading to the formation of new oceanic crust and features like mid-ocean ridges.

Front

What happens at a Convergent Boundary?

Back

At a convergent boundary, tectonic plates collide, which can result in subduction, mountain building, or volcanic activity.
