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 ocean?

Back

Convection currents in the ocean are caused by the uneven heating of water, which creates differences in water density, leading to movement.

How does temperature affect water density?

Back

Cold water is denser than warm water, which causes warm water to rise and cold water to sink.

What role does salinity play in water density?

Back

Salt water is denser than fresh water, so cold salt water is denser than warm salt water.

What are the three main convection cells in the atmosphere?

Back

The three main convection cells are the Hadley Cell, Ferrel Cell, and Polar Cell.

What is the significance of the 30-degree latitude in convection cells?

Back

At approximately 30 degrees latitude, the Hadley Cell descends, creating high-pressure areas and influencing weather patterns.

What is the process of conduction in relation to wind heating?

Back

Conduction is the transfer of heat from the Earth's surface to the air above it, warming the air and affecting wind patterns.

How do ocean currents influence climate?

Back

Ocean currents help regulate climate by distributing heat around the planet, affecting weather patterns and temperatures.
