Plate Boundaries (Shortened)

Front

What are trenches?

Back

Trenches are some of the deepest spots on the ocean floor, formed by the subduction of one tectonic plate beneath another.

Front

What type of plate boundary is formed when two plates collide?

Back

Convergent boundary.

Front

What occurs at a divergent boundary?

Back

At a divergent boundary, tectonic plates move apart, leading to the formation of new oceanic crust, such as at mid-ocean ridges.

Front

What geological features are commonly associated with convergent boundaries?

Back

Island arcs, subduction zones, volcanic mountains, and trenches.

Front

What is the Mid Atlantic Ridge?

Back

The Mid Atlantic Ridge is a divergent boundary where the ocean floor is spreading apart, creating new crust.

Front

What is a volcano?

Back

A volcano is a geological feature that forms when magma from beneath the Earth's crust escapes to the surface.

Front

What does the theory of continental drift propose?

Back

The theory of continental drift states that continents were once joined in a super-continent and have moved apart over time.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often associated with volcanic activity.

Front

What is a transform fault?

Back

A transform fault is a type of boundary where two tectonic plates slide past each other horizontally.

Front

What is the difference between convergent and divergent boundaries?

Back

Convergent boundaries involve plates colliding, while divergent boundaries involve plates moving apart.
