Facts About Acid Rain

Acid rain

is a serious environmental problem which affects many regions, especially in the U.S. and Canada. It can be defined as the precipitation which has high amounts of acids. Most of the times, acid rain occurs due to lightning strikes and volcanoes. But one of the main reason for acid rains is high levels of noxious gases released by automobiles and factories. These noxious gases have a negative impact on the ecological balance. Read on to know a few facts about acid rain.

Acid rain can be related to acid deposition. This deposition includes dry as well as wet deposition. Adverse effects of acid rain can be seen on the human health, soils, forests and fauna and flora. This is also responsible for resulting in extinction of many species.

Dry Depositions

In dry regions, the acidified chemicals mixes with smoke or dust. These drops on the ground in the form of dry deposits which eventually sediment to the ground. Gradually, these deposits are washed off by rains. The rain water further acidifies the acid chemicals. Nearly 50% of the acidity in the atmosphere falls back on ground in the form of dry deposits.

Wet Depositions

A few elements of wet deposits are acidic snow, acidic fog and acidic rain. In wet regions, the acid chemicals present in the air will drop on the ground in the form of mist, fog and rain. This acidic run off flows on the ground surface, which has adverse effects on several animals and plants.

The negative effects depends on various factors such as the chemistry and type of soil which comes in contact with acid rain. The acid runoff also adversely affects the aquatic life present in various water bodies.
