Convection Currents

Front

What causes heat transfer by convection?

Back

Differences in temperature and density.

Front

Why do we have currents in the ocean and air?

Back

The sun heats air and water more at the equator because it receives more direct sunlight.

Front

When do particles move faster?

Back

In hot water.

Front

What happens to warm air in convection?

Back

Warm air rises.

Front

What effect does adding salt to water have on its density?

Back

It makes the water more dense compared to water without salt.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases).

Front

What role does the sun play in convection currents?

Back

The sun heats the surface of the Earth, causing differences in temperature that create convection currents.

Front

What is the relationship between temperature and density in fluids?

Back

As temperature increases, density typically 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 top and cooler water sinks.

Front

How does convection affect weather patterns?

Back

Convection currents in the atmosphere help distribute heat, influencing wind and weather.
