Tectonic Plate Boundaries

Front

What are convection currents?

Back

Circular currents in the mantle caused by the magma being heated by the core of the Earth.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates are moving away from each other, allowing magma to rise and create new crust.

Front

What is subduction?

Back

The process where one tectonic plate is pushed below another at a convergent boundary.

Front

What is a convergent boundary?

Back

A boundary between two colliding tectonic plates, often associated with mountain building, ocean trenches, and volcanic islands.

Front

What is an example of a divergent boundary?

Back

Mid-Atlantic Ridge (Atlantic Ocean).

Front

What happens at a transform boundary?

Back

Two tectonic plates slide past each other horizontally.

Front

What geological features are commonly formed at convergent boundaries?

Back

Mountains, ocean trenches, and volcanic islands.

Front

What is the role of magma in tectonic plate movement?

Back

Magma rises and creates new crust at divergent boundaries, while it can also be involved in subduction at convergent boundaries.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner, while continental plates are thicker and less dense.

Front

What is the Ring of Fire?

Back

A major area in the Pacific Ocean where many earthquakes and volcanic eruptions occur, primarily due to tectonic plate boundaries.
