Question

Acid rain affectt the growth of plants and animals

Answer 1

Answer:

Acid rain damages the leaves of trees and plants, thus limiting their growth and exposing them to the metals in the air from the toxic rain. Depending on the severity of the damage, the vegetation can be stunted in its growth or the foliage can be stripped away.

Explanation:

Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Some governments have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes, and sulfur dioxide is produced by volcanic eruptions. Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.

Answer 2

Acid rain is the rainfall or any other form of precipitation which has very low pH value, ( 4.2- 4.4) they are highly acidic in nature and causes great damages to plants, and animals.

The pH value of rainfall in also slightly acidic, around 5.6, but acid rains have pH value of about 4.2 to 4.4

Explanation:

• The major cause of acid rain is human activities like burning of fossil fuels, thermal power plants, etc.
• It causes various types of damages to plants because the young leaves of the plants are destroyed due to such rains.
• Also it has been found that areas where acid rains are prevalent have tress with stunted growth.
• When these acid rain water mixes with the water of surrounding water bodies the aquatic life of such systems is highly disrupted.
• Small animals like snail, frogs, clams,etc are more affected.
• The eggs of the fish could not hatch in such waters and hence it causes imbalance in their population.
• Additionally, acid rain washes the minerals present in the soil and can also wash aluminium from the clay particles of the soil.
• Acid rain also causes damage to various structures made up of marble, or limestone.
