Infrared or longwave radiation is emitted by clouds, the Earth's surface and the Earth's atmosphere.
True False

Sulfur dioxide reacts with water vapor in the atmosphere to form sulfuric acid, one of the main ingredients of acid rain.
True False

Carbon monoxide is produced by the incomplete combustion of fuels.
True False

An isothermal layer is a layer insulated from the air above and below.
True False

The greenhouse effect is caused when gases in the atmosphere trap radiation which is then re-radiated to the earth.
True False

Latent heat flux refers to the heat or energy transferred through the process of phase change.
True False

A severe decrease in the concentration of ozone in the ozone layer could lead to several harmful effects. Name THREE of these effects.

Explain how deforestation contributes to the increase in concentration of atmospheric carbon dioxide.

Three atmospheric problems that have been debated intensely since the mid-1970's are: the reduction of stratospheric ozone from chemical emissions, the generation of acid rain, and climate change derived from the enhanced greenhouse effect. What do these three problems have in common? Name three.

Describe and give examples of TWO ways that heat can be transported in the atmosphere.
