Front

What causes explosive volcanic eruptions?

Back

Magma with a lot of gas causes explosive volcanic eruptions.

Front

What happens to warmer, less dense material?

Back

Warmer, less dense material rises.

Front

What is hot liquid rock under the Earth's surface called?

Back

Magma.

Front

What is the process called when warmer, less dense material rises and colder, more dense material sinks?

Back

Convection.

Front

What are the big pieces that make up the Earth's outer shell called?

Back

Lithospheric plates.

Front

What is the difference between magma and lava?

Back

Magma is found beneath the Earth's surface, while lava is magma that has reached the surface.

Front

What is the Earth's outer shell made of?

Back

The Earth's outer shell is made of lithospheric plates.

Front

What is the role of convection currents in the Earth's mantle?

Back

Convection currents help to move the lithospheric plates.

Front

What is the relationship between temperature and density in fluids?

Back

Warmer fluids are less dense and rise, while cooler fluids are denser and sink.

Front

What is a volcanic eruption?

Back

A volcanic eruption is the release of magma, gas, and ash from a volcano.
