when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain‚ snow‚ hail‚ or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries‚ coal burning factories‚ power plants and automoble engines are the main sources of sulfur dioxide and nitrogen oxide which caues acid rain. Volcaneoes

of acid rain. Acid deposition‚ more commonly known as acid rain‚ occurs when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react in the atmosphere with water‚ oxygen‚ and oxidants to form acidic compounds. This mixture forms a mild solution of sulfuric and nitric acid which then falls to the earth in either wet (rain‚ snow‚ sleet or fog) or dry (gas and particles) form. Approximately one-half of the atmosphere ’s acidity falls back to earth through dry deposition in the form of particles

PARADIGM SHIFTS A paradigm is a world view that controls the way we understand the world in which we live. A paradigm shift occurs when the dominant paradigm is replaced by a new paradigm. Some examples of paradigm shifts are given below. One of the most significant paradigm shifts occurred in science when the paradigm that united all truth into one was replaced by a paradigm that separated the revealed truth of the Bible from scientific truth. Newton wrote that‚ "He was thinking God’s thoughts

The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant‚ the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately

factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example forests depletions in Canada‚ threatening

Acid Rain Definition: The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852‚ when the English chemist Robert Agnus invented the term. From then until now‚ acid rain has been an issue of intense debate among scientists and policy makers. Acid rain‚ one of the most important environmental problems of all‚ cannot be seen. The invisible gases that cause acid

Environmental Disasters For the purpose of this article an environmental disaster is defined as a specific event caused by human activity that results in a seriously negative effect on the environment. Sometimes a natural disaster can become an environmental disaster‚ but that is a topic to be discussed elsewhere. In most cases environmental disasters are caused by human error‚ accident‚ lack of foresight‚ corner cutting during industrial processes‚ greed‚ or by simple incompetence. In other
