What causes differences in air pressure around the Earth?

Back

Warm air rises at the equator and cold air sinks at the poles.

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.

Front

What is an incorrect analogy about the greenhouse effect?

Back

The increase in greenhouse gas emissions is like placing an extra log on the fire to produce more heat.

Front

What creates convection currents in the atmosphere?

Back

Unequal heating of land and water by the sun’s rays creates convection currents.

Front

What is the relationship between convection currents and wind?

Back

Convection currents are responsible for the movement of wind on Earth.

Front

During the night, which direction does the wind blow when ocean air is warmer than land air?

Back

The wind will blow toward the water.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy by direct contact.

Front

What is the role of the sun in the heating of the Earth?

Back

The sun's rays heat the Earth's surface unevenly, leading to temperature differences.

Front

How does warm air affect air pressure?

Back

Warm air is less dense and rises, leading to lower air pressure.

Front

How does cold air affect air pressure?

Back

Cold air is denser and sinks, leading to higher air pressure.
