Convection currents 6th

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.

What causes the movement of Earth's tectonic plates?

Back

The movement of Earth's tectonic plates is primarily caused by convection currents in the mantle.

What happens to warm air?

Back

Warm air rises because it is less dense than cool air.

Where do convection currents that move tectonic plates flow?

Back

Convection currents that move the continental and oceanic plates flow in the asthenosphere, which is part of the mantle.

What happens to cool air?

Back

Cool air sinks because it is denser than warm air.

Front

How do convection currents affect weather patterns?

Back

Convection currents can create wind and influence weather patterns by moving warm and cool air around the Earth.

What is the role of density in convection currents?

Back

Density differences in fluids drive convection currents; warmer fluids are less dense and rise, while cooler fluids are denser and sink.

Front

What is an example of convection currents in water?

Back

An example of convection currents in water is when a pot of water is heated on a stove, causing the warm water to rise and the cooler water to sink.

Front

How do convection currents relate to the Earth's mantle?

Back

In the Earth's mantle, convection currents help transfer heat from the core to the surface, driving plate tectonics.

What is the relationship between temperature and density in fluids?

Back

In fluids, as temperature increases, density decreases; as temperature decreases, density increases.
