Plate Tectonics

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath the other, leading to earthquakes and volcanic activity.

Front

What is a transform boundary?

Back

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

Front

What are tectonic plates?

Back

Tectonic plates are large slabs of rock that make up Earth's surface, floating on the semi-fluid mantle beneath.

Front

How is new crust formed at divergent boundaries?

Back

New crust forms at divergent boundaries when two tectonic plates spread apart, allowing magma to rise and solidify.

Front

What was Pangea?

Back

Pangea was a supercontinent that existed millions of years ago, where all the continents were once connected.

Front

What happens at a divergent boundary?

Back

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

Front

What is the mantle?

Back

The mantle is the thick layer of rock beneath Earth's crust, composed of semi-solid rock that flows slowly.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another, often leading to volcanic activity.

Front

What are earthquakes?

Back

Earthquakes are sudden shaking of the ground caused by the movement of tectonic plates.

Front

What is a fault line?

Back

A fault line is a fracture in Earth's crust where tectonic plates meet, often associated with earthquakes.
