Convection currents 6th

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where warm air or liquid rises and cool air or liquid sinks.

Front

What happens to warm air in convection?

Back

Warm air rises.

Front

What happens to cool air in convection?

Back

Cool air sinks.

Front

What type of heat transfer occurs in the mantle of the Earth?

Back

Convection.

Front

Which direction do convection currents move in water?

Back

Convection currents move in a circular pattern: warm water rises and cool water sinks.

Front

What is an example of convection in everyday life?

Back

An example of convection is boiling water, where the hot water at the bottom rises to the top.

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection involves the movement of fluids.

Front

What role does density play in convection?

Back

In convection, warm fluids are less dense and rise, while cool fluids are more dense and sink.

Front

How do convection currents affect weather patterns?

Back

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

Front

What is the main driving force behind convection currents?

Back

The main driving force is the difference in temperature, which creates differences in density.
