Question

which of the following is true about sulfurous smog? it exists in damp, cold weather. it is formed from unburned hydrocarbons. it creates a brown haze in the air. it is formed from nitrogen oxides. question 6 (multiple choice worth 2 points) (04 03r lc) how can photochemical smog impact the environment? it can increase the number of insects in the area. it can reduce the amount of plastic in the ocean. it can increase tree and plant growth in a city. it can decrease the crop yield in a region.

Explanation:

Sulfurous smog is associated with damp, cold weather conditions. It is formed mainly from sulfur - containing compounds, not from unburned hydrocarbons (which are related to photochemical smog), not from nitrogen oxides, and it doesn't create a brown haze (which is characteristic of photochemical smog). Photochemical smog is harmful to plants and can decrease crop yield as it contains ozone and other pollutants that damage plant tissues.

Answer:

1. It exists in damp, cold weather.
2. It can decrease the crop yield in a region.
