Plate Tectonics and Boundaries

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 are the three main types of plate boundaries?

Back

Convergent, Divergent, and Transform boundaries.

Front

What occurs at a convergent boundary?

Back

Plates move towards each other, often causing earthquakes, volcanic activity, and mountain building.

Front

What is a divergent boundary?

Back

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

Front

What is seafloor spreading?

Back

The process that occurs at divergent oceanic boundaries where new oceanic crust is created as magma rises to the surface.

Front

What is subduction?

Back

The process where one tectonic plate moves under another, often leading to volcanic activity and earthquakes.

Front

What type of boundary is associated with the formation of folded mountains?

Back

Convergent boundary, particularly with continental to continental crustal interaction.

Front

What happens to oceanic crust at a convergent oceanic boundary?

Back

It is destroyed as one plate is forced under another.

Front

What is an example of a transform boundary?

Back

The San Andreas Fault in California.

Front

What geological feature is formed by a divergent boundary?

Back

Mid-ocean ridges, such as the Mid-Atlantic Ridge.
