Convection Currents

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases) caused by differences in temperature and density.

What causes convection currents in the Earth?

Back

The uneven heating on each layer inside the Earth.

Front

Why does ice float in water?

Back

Ice floats because it is less dense than water.

Front

What is the primary medium for convection currents?

Back

Convection currents primarily occur in liquids and gases.

Front

True or False: Convection currents can be felt through empty space.

Back

False. Convection requires a medium (liquid or gas) to transfer heat.

Front

Can convection currents occur in solids?

Back

No, convection currents only move in liquids and gases.

Front

What role does temperature play in convection?

Back

Temperature differences cause changes in density, leading to the movement of fluid and the formation of convection currents.

How do convection currents affect weather patterns?

Back

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

What is the relationship between density and buoyancy in convection?

Back

In convection, less dense fluids rise while denser fluids sink, creating a cycle of movement.
