Question

certain eye irritations may be worsened in cities most likely by _, which is a result of acid deposition; natural air pollutants and particulate matter particulate matter; odorless gas collecting in an area photochemical smog; reactions between light, heat, and vocs sulfurous smog; gas burning in very hot weather question 8 (multiple choice worth 2 points) which of the following is an environmental indicator of acid deposition? decreased eutrophication of aquatic ecosystems increased photosynthesis from the breakdown of leaves increased water vapor over vegetation and crops decreased ph levels in lakes, rivers, or other bodies of water

Explanation:

1. For the first question about eye - irritations in cities: Photochemical smog is formed from reactions between light, heat, and volatile organic compounds (VOCs). It is a common urban air - pollutant that can worsen eye irritations.
2. For the second question about acid - deposition indicators: Acid deposition leads to a decrease in the pH levels of water bodies such as lakes, rivers, etc. as it adds acidic components to them.

Answer:

1. C. photochemical smog; reactions between light, heat, and VOCs
2. D. Decreased pH levels in lakes, rivers, or other bodies of water
