Answer:
I, II and III
Explanation:
Photochemical smog is a brownish-gray haze caused by the action of solar ultraviolet radiation on atmosphere polluted with hydrocarbons and oxides of nitrogen. It contains anthropogenic air pollutants, mainly ozone, nitric acid, and organic compounds, which are trapped near the ground by temperature inversion. These pollutants and also some others can affect human health and cause damage to plants. Photochemical smog often has an unpleasant odor due to some of its gaseous components. The term smog (not to be confused with photochemical smog) is commonly used to represent a near-ground haze made of a combination of smoke and fog rather than ozone, nitric acid, and organic compounds.

Answer: True</h3>
Healthy top soil is needed to grow crops, which in turn some of it becomes food. Erosion is the process in which top soil is carried away by the wind or rain water (depositing it into nearby lakes or streams). Without this top soil, farming becomes more difficult and crop yields likely decrease. In some cases, no crops can be grown at all. An extreme example of soil erosion, specifically wind-driven soil erosion, is the 1930s dust bowl during the Great Depression. This occurred due to over-farming and it led to massive dust storms. In turn, it caused many farmers to leave the area.
