8.10A The Sun's Energy

Front

What process creates winds in our atmosphere?

Back

Winds are created by the uneven heating of the air in the atmosphere.

Front

Why does warm air rise in the atmosphere?

Back

Warm air is less dense than cool air, so it rises.

Front

What is the primary energy source that heats the Earth's atmosphere?

Back

The Sun is the primary energy source that heats our planet’s atmosphere.

Front

What is the cycle that powers ocean currents, weather, and tectonic plates?

Back

The cycle is called convection current.

Front

What is an example of heat transfer by convection?

Back

An illustration of heat being transferred by wind is an example of convection.

Front

Define convection current.

Back

Convection current is the movement of fluid (liquid or gas) caused by the difference in temperature and density.

Front

What role does the Sun play in weather patterns?

Back

The Sun warms the atmosphere, driving convection currents that influence weather patterns.

Front

How does uneven heating affect air pressure?

Back

Uneven heating causes differences in air pressure, leading to wind.

Front

What is the relationship between density and temperature in air?

Back

As air is heated, it becomes less dense and rises; cooler air is denser and sinks.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.
