The ozone layer helps life on Earth because ozone

• modifies the normal El Nino weather.

• reflects insolation from the sun.

• absorbs damaging ultraviolet radiation from the sun.

• deflects winds from a straight line to a curved path.

Global warming is most closely associated with

• increased use of solar panels.

• more factories.

• the rate of species extinction.

• getting rid of environmental wastes.

In most states, automobiles must be inspected every year to make sure that the exhaust fumes they emit do not contain high levels of pollutants, such as carbon monoxide. This process is a way humans attempt to:

• control the water cycle.

• recycle nutrients from one ecosystem to another.

• control energy flow in natural ecosystems.

• maintain the quality of the atmosphere.
