Convection Currents review

Front

What causes the movement of tectonic plates?

Back

Convection currents in the mantle.

Front

What happens to heat during convection currents?

Back

Heat rises.

Front

What occurs to hotter material in the Earth's mantle?

Back

It becomes less dense and rises.

Front

What is the cooling source for convection in the mantle?

Back

The Crust.

Front

What is one reason Earth's tectonic plates move?

Back

Convection currents in the mantle.

Front

Define convection currents.

Back

Convection currents are the movement of fluid caused by differences in temperature and density.

Front

What role does density play in convection currents?

Back

Less dense materials rise, while more dense materials sink.

Front

How do convection currents affect the Earth's surface?

Back

They contribute to the movement of tectonic plates, leading to earthquakes and volcanic activity.

Front

What is the mantle?

Back

The mantle is the thick layer of rock between the Earth's crust and core.

Front

What is the relationship between temperature and density in convection?

Back

As temperature increases, density decreases, causing materials to rise.
