Plate Tectonics: Processes

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 Seafloor Spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What is Subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.

Front

What is Fold Mountain Building?

Back

The process of mountain formation that occurs when two tectonic plates collide and push the Earth's crust upwards.

Front

What is Rifting?

Back

The process where tectonic plates move away from each other, leading to the formation of new crust.

Front

What type of crust is more dense, oceanic or continental?

Back

Oceanic crust is more dense than continental crust.

Front

What happens during Subduction?

Back

One tectonic plate sinks beneath another, often leading to volcanic activity.

Front

What is the result of Seafloor Spreading?

Back

The creation of new oceanic crust and the widening of ocean basins.

Front

What is the main driving force behind Plate Tectonics?

Back

Convection currents in the Earth's mantle.

Front

What is a Transform Boundary?

Back

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