Convection and Air Pressure Concepts

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's mantle?

Back

Convection currents in the Earth's mantle are caused by the heat from the Earth's core, which creates a cycle of rising hot material and sinking cooler material.

Front

How do ocean currents affect climate?

Back

Ocean currents help regulate climate by distributing heat around the planet, influencing weather patterns and temperatures in coastal regions.

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a surface, measured in units such as pascals or millibars.

Front

What happens to air pressure as altitude increases?

Back

As altitude increases, air pressure decreases because there is less air above the surface exerting force.

Front

What is the relationship between temperature and air pressure?

Back

Generally, as temperature increases, air pressure decreases because warm air is less dense and rises.

Front

What is transpiration in plants?

Back

Transpiration is the process by which plants release water vapor from their leaves into the atmosphere.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air and water currents, caused by the rotation of the Earth.

Front

How do landmasses affect ocean currents?

Back

Landmasses can change the direction of ocean currents, causing them to flow around continents and altering their paths.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.
