Pangea and Plate Boundaries

Front

What is Pangea?

Back

Pangea was a supercontinent that existed around 335 million years ago, where all the continents were joined together.

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.

What is a divergent boundary?

Back

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

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 under the other.

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, leading to earthquakes.

What is the role of convection currents in the mantle?

Back

Convection currents in the mantle drive the movement of tectonic plates, causing them to shift and interact.

How do earthquakes occur at plate boundaries?

Back

Earthquakes occur when stress builds up at plate boundaries and is released suddenly, causing the ground to shake.

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates move apart, allowing magma to rise and create new oceanic crust.
