Assertion (A):- Acid rain is harmful for agriculture, trees and plants
Acid rain affects plants directly and decreases soil quality to reduce yields from agriculture.
Acid rain influences both the quality and yield of agricultural products. Acid rain can damage the leaves of vegetables such as spinach and cause blemishes on delicate products such as tomatoes. The production and quality of root vegetables is reduced.
Acid rain can have harmful effects on plants, animals and humans. It is caused when gaseous compounds of ammonium, carbon, nitrogen, and sulphur are released into the atmosphere. The wind carries the gases high into the sky. There the compounds react with the water in the atmosphere and acids are made. In 1852, Robert Angus Smith showed the relationship between acid rain and atmospheric pollution in Manchester. He coined the term "acid rain" in 1872.
Reason (R):- it dissolves and washes away nutrients needed for their growth.
- Both A and R are correct and R is the correct explanation of A.
- Both A and R are correct and R is not the correct explanation of A.
- Both A and R are not correct.
- A is correct but R is not correct.
Answer: Both A and R are correct and R is the correct explanation of A.
Acid rain influences both the quality and yield of agricultural products. Acid rain can damage the leaves of vegetables such as spinach and cause blemishes on delicate products such as tomatoes. The production and quality of root vegetables is reduced.
Sulphur dioxide and nitrogen oxides both combine with water in the atmosphere to create acid rain. Acid rain acidifies the soils and waters where it falls, killing off plants. Many industrial processes produce large quantities of pollutants including sulphur dioxide and nitrous oxide. These are also produced by car engines and are emitted in the exhaust. When sulphur dioxide and nitrous oxide react with water vapour in the atmosphere, acids are produced. The result is what is termed acid rain, which causes serious damage to plants.
Acid Rain
One of the tough concerns of today's era is the Acid rain which can have a devastating effect on overall organisms living on the Earth. Acid rain is rain that is unusually acidic and highly corrosive in nature. It is rain with high levels of hydrogen ions (low pH). It may be defined as "rainwater having pH less than 5.6".Acid rain can have harmful effects on plants, animals and humans. It is caused when gaseous compounds of ammonium, carbon, nitrogen, and sulphur are released into the atmosphere. The wind carries the gases high into the sky. There the compounds react with the water in the atmosphere and acids are made. In 1852, Robert Angus Smith showed the relationship between acid rain and atmospheric pollution in Manchester.
