Process Description: How to Write about a Sequence of Events Posted by Dennis G. Jerz‚ on July 16th‚ 2011 This document describes how to write a process description‚ a variation of the short report designed to convey to the reader how a change takes place through a series of stages. The process description examines an event over time; by contrast‚ the mechanism description focuses on an object in space. Use a process description when your intended reader wants to learn about the action in question

species was the least tolerant? The names of the species used in the experiment were clam‚ dragonfly‚ and side swimmer. The specie that was the most tolerant was the dragonfly and the least tolerant was the clam. Describe how acid precipitation affects ecosystems. Acid precipitation affects the ecosystem‚ for example‚ lowering ph in water when it falls into the lake which kills some aquatic organisms. What is an indicator species? How are indicator species used to assess pollution levels in the

from different sources that we cannot control. For example‚ forest fires‚ dust storms‚ and volcanoes. One of the sources of air pollution is acid rain. Raindrops that are combined with polluted air create acid rain. Acid rain mainly causes the erosion of buildings‚ destruction of crops‚ and many other assets. Global warming is also caused by acid rain. Many scientists predict that significant alterations in climate patterns could become more noticeable in the next few years. The global average

of all over the world die due to direct or indirect effects of air pollution. 3. Acid Rain: Acid raining is another effects of air pollution. Harmful gases like nitrogen oxides and sulfur oxides are released into the atmosphere during the burning of fossil fuels. When it rains‚ the water droplets combines with these air pollutants‚ becomes acidic and then falls on the ground in the form of acid rain. Acid rain can cause great damage to human‚ animals and crops. 4. Depletion of Ozone layer:

“Acid Rain” Environmental science What is Acid Rain? Acid rain is a rain or any other form of precipitation like rain‚ fog‚ snow‚ or hail that contains harmful substances higher than normal amounts of such as nitrogen and sulfur oxides‚ that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. The acid deposition is occurs

Acid Rain Acid rain‚ or acid desposition‚ is simply common rainfall that has been polluted sufficiently by atmospheric pollution. Acid rain contains two types of acids: nitric and sulfuric. These chemicals‚ or precursors‚ are emited by natural sources such as volcanoes and decaying vegetation. Man-made sources are also primary causes for emissions of sulfur dioxide and nitrogen oxides that come from fossil fuel combustion. The most common emiters of these fossil fuels are power plants‚ factories

Acid Rain Done By: Francis Lolas Teacher: Christine Due Date: 19/9/2012 Grade: 10 MYP 5 A There are many possible solutions to the problem that we are facing nowadays that is Acid Rain. Acid rain is formed from two main gases that are released in the atmosphere which are sulphur oxide and nitrogen oxide. I will talk later about the solutions for acid rain and the effect of this rain and what are the two forms of acid deposition. I have also watched some videos about acid

Acid rain causes acidification of lakes and streams and contributes to the damage of trees at high elevations (for example‚ red spruce trees above 2‚000 feet) and many sensitive forest soils. In addition‚ acid rain accelerates the decay of building materials and paints‚ including irreplaceable buildings‚ statues‚ and sculptures that are part of our nation’s cultural heritage. Prior to falling to the earth‚ sulfur dioxide (SO2) and nitrogen oxide (NOx) gases and their particulate matter derivatives—sulfates

Life Effects of Acid Rain There are many different types of negative effects acid rain has on the world. Acid rain is the mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Pollution contributes to the forming of acid rain. One of the main causes is industrial burning of coal and other fossil fuels the oxides they contain and combine with atmospheric water which forms acids. One of the effects of acid rain is the loss of fish

sources of acid precipitation in your community? What impact can this have on the environment in your region? Some of the probable sources of acid precipitation is Fog‚ and rain. During the summer it hardly rains which makes it hard for our crops to grow‚ also since we are in the valley it makes it hard for us to get the water that we need. During the fall it gets very foggy in the mornings and it makes it very difficult to see while your driving. Prevailing winds can also transport the acid precipitation
