Convection Currents

Front

What are convection currents?

Back

Convection currents are the movement of fluid (liquid or gas) caused by differences in temperature and density, where warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What happens to warmer air in convection currents?

Back

Warmer air rises because it is less dense than cooler air.

Front

What happens to cooler air in convection currents?

Back

Cooler air sinks because it is more dense than warmer air.

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often described as how tightly packed the particles are in a given space.

Front

Which type of air is more dense: cold air or hot air?

Back

Cold air is more dense than hot air.

Front

What do convection currents create in the atmosphere?

Back

Convection currents create winds in the atmosphere.

Front

What do convection currents create in water?

Back

Convection currents create ocean currents in water.

Front

True or False: Convection currents occur due to uneven heating of the Earth's surface.

Back

True.

Front

What is the role of the equator in convection currents?

Back

The equator receives more direct sunlight, causing warmer air to rise, which contributes to convection currents.

Front

What is the role of the poles in convection currents?

Back

The poles are cooler, causing the denser, cooler air to sink, which also contributes to convection currents.
