Plate Tectonics

Front

What is Plate Tectonics?

Back

The theory that explains the structure and movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What is the difference between continental crust and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.

Front

Which type of crust is denser?

Back

Oceanic crust is denser than continental crust.

Front

What is a convergent boundary?

Back

A tectonic boundary where two plates move towards each other, often causing one plate to be forced beneath the other.

Front

What geological features are formed at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.

Front

What is a divergent boundary?

Back

A tectonic boundary where two plates move away from each other, leading to the formation of new crust.

Front

What geological features are formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys.

Front

What is a transform boundary?

Back

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

Front

What is subduction?

Back

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

Front

What type of stress causes rock to be pulled apart?

Back

Tension causes rock to be pulled apart, forming normal faults and rift valleys.
