Tectonic Plate Interactions and Effects

Front

What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other horizontally, often causing earthquakes.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates come together, often leading to the formation of mountains or subduction zones.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move apart from each other, often resulting in sea-floor spreading.

Front

What is a rift valley?

Back

A rift valley is a lowland region that forms where tectonic plates move apart, creating a valley.

Front

What is a hot spot?

Back

A hot spot is an area in the mantle where hot rock rises to the surface, often creating volcanoes.

Front

What geological feature is created when two continental crusts push together?

Back

Mountains are formed when two continental crusts collide at a convergent boundary.

Front

Which rock layer is typically the oldest in a geological diagram?

Back

The bottom layer (often labeled A) is usually the oldest due to the principle of superposition.

Front

What natural disaster is commonly associated with transform boundaries?

Back

Earthquakes are commonly associated with transform boundaries due to the friction between sliding plates.

Front

What happens at a subduction zone?

Back

At a subduction zone, one tectonic plate is forced under another, leading to volcanic activity and earthquakes.

Front

What is sea-floor spreading?

Back

Sea-floor spreading is the process by which new oceanic crust is formed at divergent boundaries as tectonic plates move apart.
