These soils are dry soils, as they get little amount of precipitation, thus they do not have high amounts of organic matter. Soil formation is restricted near to the surface as any water the desert does receive, does not move through the soil. Soils in this biome, usually have little or no foliage cover, mostly due to the fact that most of it is destroyed by the strong sun’s rays. Desert soils can differ in depth, they can be deep, shallow, salty or be covered with a desert pavement, or have a cement-like horizon close to the surface. They have a B horizon, which often contains calcium carbonate, gypsum and salts.
Acid rain formation is affected by both natural and man-made sources as well as burning of fossil fuel that emits both sulfur dioxide and nitrogen oxides. When sulfur dioxide and nitrogen oxides mix with other components in the atmosphere such as oxygen, other chemicals and water they form acidic components which go back into the hydrologic cycle forming acidic rain with a mild solution of both sulfuric acid and nitric acid. This acid deposition is very harmful to human beings, cars, and wildlife, aquatic life and water surfaces among others. Acid rain occurs mainly due to human activities. Human beings need power energy to survive and carry out a lot of their common activities in their daily lives.
Introduction: Rain is one of the most essential ingredients for the survival of human and animal life on Earth. Although rain is naturally acidic, it is being increasingly acidified by the presence of pollutants in the environment. The term used to describe this problem is “acid rain”  Burning of fossil fuels for industrial and transport sector have led to increase in concentrations of gaseous and particulate pollutants in the atmosphere leading to air pollution.  The oxides of Carbon, Sulfur and Nitrogen present in the air combine with the moisture in the air and form sulphuric acid, carbonic acid and nitric acid, respectively. When it rains or snow, these acids are brought to the earth in what is called acid rain.
The increase of acid rain is increasingly proving to be a very distressing global issue. Acid rain defines any type of precipitation with excessive quantities of nitric and sulfuric acids. The formation of acid rain can be expressed by the equations: H2O(l) + SO2(g) ==> H2SO3(g) and 2NO2(g) + H2O(l) ==> HNO3(aq) + HNO2(g). It can appear in the form of fog, snow, and tiny bits of dry substance that settle on Earth. The biggest cause of acid rain is the burning and combustion of fossil fuels by factories, power plants, and automobiles.
Factories may dump toxic chemicals, or rainwater may carry harmful pesticides or animal waste from farms. Such harmful substances can have negative impacts on the wildlife that live in these water bodies. These substances may also enter the groundwater, which is where people get their water to drink! Wetlands reduce the amount of these harmful substances that enter a stream, river, pond, or lake by acting like a strainer that filters out the bad stuff. When these substances enter a wetland, before reaching the water body, wetland plants will take many of the harmful substances into their roots and change the harmful substances into less harmful ones before they are released to the water body.
As the wind blow, these particles will get to another place. Acidic particles and gases can also deposit from the atmosphere in the absence of moisture as dry deposition. The acidic particles and gases may deposit to surfaces (water bodies, vegetation, buildings) quickly or may react during atmospheric transport to form larger particles that can be harmful to human health. When the accumulated acids are washed off a surface by the next rain, this acidic
The oxides are then transported throughout the atmosphere. When the oxides make contact with the water, a chemical reaction happens. For the examples, when combined with water the oxides form carbonic acids, nitric acid and sulfuric acid. This means that the pH of rain is lower and the acidity is higher. Acid rainfall is harmful to forests, lakes, streams, buildings and other objects and can cause certain health problems.
Water is a component that absorbs heat or solar radiation that reaches the surface of the earth. Material water vapour or ice in a layer of the atmosphere is considered to escort the incoming sunlight to be accepted and not ruin the life of the earth. However, we are facing now with the climate change case that occurs in the earth. Climate change is no longer a new phenomenon for the global climate because it has changed since time immemorial. Climate is usually defined as the average weather in one region.
The persistent sun exposure burns the skin both on your lip and skin. But, the darkness of the lips is more focused. The UV rays also trigger the melanin deposition on the various parts of the body. But, the face and lips are most harmed. So, to get lighten your lips as far as possible you should not move more in the harmful sun exposure.
So as rain falls through the atmosphere, flows over and through the earth’s surface it is constantly dissolving material. Therefore water supplies have a natural variety in quality, which depends largely on its source.R-S Humans depend on this resource for all their needs of existence. Moreover, wherever
