Plate Tectonics 1

Front

What is convection?

Back

Convection is the process of heat transfer in fluids (liquids and gases) where hot, less dense material rises, and cool, more dense material sinks, creating a circular motion.

Front

Which direction does hot material move in convection?

Back

Hot material moves up in convection.

Front

Which direction does cool material move in convection?

Back

Cool material moves down in convection.

Front

What is the relationship between density and convection?

Back

In convection, less dense material rises while more dense material sinks.

Front

What type of crust is denser: oceanic or continental?

Back

Oceanic crust is denser than continental crust.

Front

What happens at a transform boundary?

Back

At a transform boundary, two tectonic plates slide past each other horizontally.

Front

What is a tectonic plate?

Back

A tectonic plate is a large, rigid piece of the Earth's lithosphere that moves and interacts with other plates.

Front

What is the theory of plate tectonics?

Back

The theory of plate tectonics explains how the Earth's lithosphere is divided into plates that move and interact, causing geological phenomena.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What is a divergent boundary?

Back

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