Convection on Earth

Front

What is convection?

Back

Convection is the transfer of heat through a fluid (liquid or gas) caused by the movement of the fluid itself.

Front

What is the main cause of wind on Earth?

Back

Wind is created when radiation from the Sun heats air in the atmosphere, causing differences in air pressure.

Front

What is a land breeze?

Back

A land breeze is a wind that flows from land to sea, typically occurring at night when the land cools faster than the sea.

Front

What is a sea breeze?

Back

A sea breeze is a wind that flows from sea to land, usually occurring during the day when the land heats up faster than the sea.

Front

What factors influence ocean currents?

Back

Ocean currents are influenced by temperature differences, salinity, wind patterns, and the rotation of the Earth.

Front

How does temperature affect water density?

Back

Warm water is less dense than cold water, causing it to rise to the surface.

Front

What is salinity?

Back

Salinity is the concentration of salt in water, which affects water density and ocean currents.

Front

What role does the Earth's rotation play in ocean currents?

Back

The Earth's rotation causes the Coriolis effect, which influences the direction of ocean currents.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air and water, due to the rotation of the Earth.

Front

What is the difference between surface currents and deep ocean currents?

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep ocean currents are driven by differences in temperature and salinity.
