Plate Tectonics

Front

What causes the movement of tectonic plates?

Back

The movement of tectonic plates is caused by convection currents in the Asthenosphere.

Front

Which layer of the Earth is made up of liquid metal?

Back

The Outer Core is the layer of the Earth made up of liquid metal.

Front

What are the three types of plate boundaries?

Back

The three types of plate boundaries are convergent, divergent, and transform.

Front

What type of plate boundary is formed when one plate pushes another plate under it?

Back

This type of boundary is called a convergent boundary.

Front

What is subduction?

Back

Subduction is the process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.

Front

What is the Moho discontinuity?

Back

The Moho discontinuity is the boundary between the Earth's crust and the underlying mantle.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new oceanic crust.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What geological feature is commonly associated with convergent boundaries?

Back

Mountains and deep ocean trenches are commonly associated with convergent boundaries.

Front

What is the significance of the Asthenosphere in plate tectonics?

Back

The Asthenosphere is a semi-fluid layer that allows tectonic plates to move due to convection currents.
