Convection Currents

Front

What causes heat transfer by convection?

Back

Differences in temperature and density.

Front

What happens to warm air in convection?

Back

Warm air rises.

Front

In convection, heat transfers from an area of ____ temperature to an area of ___ temperature.

Back

High temperature to low temperature.

Front

What is the cycle that powers ocean currents, weather, and tectonic plates called?

Back

Convection current.

Front

What do convection currents in the mantle cause?

Back

Tectonic plates to move.

Front

What is the primary mechanism of heat transfer in fluids?

Back

Convection.

Front

What role does density play in convection currents?

Back

Density differences drive the movement of fluids, causing warmer, less dense fluid to rise and cooler, denser fluid to sink.

Front

How do convection currents affect weather patterns?

Back

They help distribute heat in the atmosphere, influencing wind and precipitation patterns.

Front

What is the relationship between temperature and density in convection?

Back

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

Front

What is an example of convection in everyday life?

Back

Boiling water, where hot water rises to the surface and cooler water sinks.
