What is an estimated damage caused by acid rain to buildings in USA?
Acid rain is capable of damaging the buildings and historic monuments which are made up of rocks such as limestone and marble. Which among the following is the end product of such reaction?
In acid rain, water dissolves toxic elements from rocks such as:
Burning of coal produces oxides of sulphur and nitrogen which combined with water vapor leads to
Acid deposition causes
Acid rain contains
Which two gases involved in formation of acid rain?
Acid rain mainly result from
Read the passage and answer the following questions:
Acid rain is formed after the burning of fossil fuels releases compounds containing nitrogen and sulfur into the atmosphere. Sunlight and rain bring about chemical reactions that convert these compounds into nitric acid and sulfur dioxide, which combine with water droplets to form acid rain. Acid rain typically has a pH of approximately 5.5. "The higher acidity of soil and water affects many living organisms adversely. As the pH of lake water falls, fish become ill and die. Table 1 shows the effects of pH on the size of adult fish.
| pH of lake | Average length of fish (cm) | Average mass of fish (g) |
|---|---|---|
| 7.5 | 30 cm | 454 g |
| 7.0 | 28 cm | 450 g |
| 6.5 | 29 cm | 453 g |
| 6.0 | 25 cm | 401 g |
| 5.5 | 20 cm | 288 g |
| 5.0 | 17 cm | 127 g |
| 4.5 | All fish died | All fish died |
Mycorrhizal fungi, which form a mutualistic association with many plant roots, are particularly sensitive to the effects of acid rain. These fungi facilitate the
absorption of water and nutrients by the plants; in turn, the plants provide sugars and amino acids without which the fungi could not survive.
Fungi are classified as
