How do temperature Inversions affect air currents?

• A layer of cold, polluted air mixes with the warm air from the surface and creates a smog-like layer

• A layer of slightly warmer air prevents the warm, polluted air from rising, causing a build up of pollution near the surface

• A layer of smoke causes temperatures to lower near the surface of the earth, causing more pollution in the air.

What effect do temperature inversions have?

• traps heat and raises the temperature beneath it

• traps cold air and lowers the temperature beneath it

• traps emissions and can accumulate beneath it

• traps the ozone layer

During a temperature inversion,___

• there is very little mixing of air masses

• air masses are continuously circulated

• pollution tends to dissipate more rapidly than normal

• air quality improves due to the even distribution of air masses

Temperature inversions impact air pollution by

• Increasing air circulation which helps air pollution dissipate

• Increasing air circulation trapping air pollution close to the ground

• Reducing air circulation trapping air pollution close to the ground

• Reducing air circulation which helps air pollution dissipate

During a temperature inversion

• Warm air gets trapped under cold air

• Warm air rises and cooler air sinks

• Cool air rises and warmer air sinks

• Cool air gets trapped under warmer air

What is a temperature inversion?

• A reversal of the normal behavior of temperature in the troposphere

• A phenomenon where warm air rises above cold air

• A situation where cold air rises above warm air

• A condition where temperature remains constant with altitude
