Seafloor Spreading & Plate Tectonics Review

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often resulting in one plate being forced beneath the other, leading to geological features such as mountains, earthquakes, and volcanic activity.

Front

What type of faults are associated with divergent boundaries?

Back

Normal faults are associated with divergent boundaries, where tectonic plates move apart, causing the crust to stretch and break.

Front

What geological event is commonly associated with convergent boundaries?

Back

Earthquakes are commonly associated with convergent boundaries due to the intense pressure and friction as plates collide.

Front

What landforms are created by divergent boundaries?

Back

Divergent boundaries create landforms such as mid-ocean ridges and rift valleys, where tectonic plates pull apart.

Front

What drives the movement of Earth's tectonic plates?

Back

The movement of Earth's tectonic plates is driven by convection currents in the mantle, which are caused by the heat from the Earth's core.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, leading to earthquakes but not typically creating or destroying crust.

Front

What is the Great Rift Valley an example of?

Back

The Great Rift Valley is an example of a divergent boundary, where tectonic plates are moving apart.

Front

What type of geological activity is common at transform boundaries?

Back

Earthquakes are common at transform boundaries due to the friction between sliding plates.

Front

What is the Mid-Ocean Ridge?

Back

The Mid-Ocean Ridge is a continuous mountain range formed by divergent tectonic plates, where new oceanic crust is created.

Front

What happens at a subduction zone?

Back

At a subduction zone, one tectonic plate is forced under another, leading to volcanic activity and the formation of deep ocean trenches.
