What is the primary heat source for convection in the mantle?

Back

The Core.

Front

What causes convection currents in the mantle?

Back

Differences in temperature and density.

Front

How do convection cycles in the mantle affect the crust?

Back

The crust moves in the same direction as the convection cycle.

Front

How does heat transfer between objects?

Back

Heat moves from a warmer object to a cooler object.

What role does density play in convection currents?

Back

Differences in density cause fluids to rise and sink, creating convection currents.

Front

What is the mantle?

Back

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

How does the Earth's rotation affect convection currents?

Back

The Earth's rotation can influence the direction and pattern of convection currents.

Front

What is the relationship between temperature and density in convection?

Back

As temperature increases, density decreases, causing warmer fluids to rise.
