What is a plate boundary?

Back

A plate boundary is the region where two tectonic plates meet. These boundaries can be classified into three main types: convergent, divergent, and transform.

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates move towards each other, which can result in one plate being forced beneath the other, leading to subduction.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move apart from each other, allowing magma to rise and create new crust, often forming mid-ocean ridges.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What are hot spots?

Back

Hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle.

Front

How do hot spots form?

Back

Hot spots are created when magma rises through the Earth's crust, and as the tectonic plate moves, it forms a series of land features over time.

Front

What is an example of a hot spot?

Back

An example of a hot spot is the Hawaiian Islands, which were formed by volcanic activity over a stationary hot spot.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another plate and sinks into the mantle as the plates converge.

Front

What geological features are formed at convergent boundaries?

Back

Convergent boundaries can form mountain ranges, deep ocean trenches, and volcanic arcs.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur, primarily due to tectonic plate movements.
