Pollution Pollution is the addition to the ecosystem of someting which has a detrimental effect on it. One of the most important causes of pollution is the high rate of energy usage by modern‚ growing populations. Different kinds of pollution are found. In this section we will discuss: 1. Air Pollution. 2. Water Pollution. 3. Land Pollution. Air Pollution Air pollution is the accumulation in the atmosphere of substances that‚ in sufficient concentrations‚ endanger human health or

Smoke in the air from factories is a type of pollution as it is bad for the lungs when breathed in. Sewage in drinking water is another type of pollution‚ as it can make people ill because it contains germs and viruses. People living next to a building site where there is too much noise can become sick as

Soil properties are the result of the five soil forming factors; parent rock‚ climate‚ topography‚ organisms and time (Bockheim‚ et.al.‚ 2014). This is why there is a wide variety of soil types throughout Australia‚ but are there systematic differences between different regions? This essay will determine whether Australian tropical soils are different from soils of the rest of the country. The tropics are the regions between the latitude lines of the Tropic of Cancer and the Tropic of Capricorn (Seidel

reality or fiction One of the greatest problems that the world is facing today is that of environmental pollution‚ increasing with every passing year and causing grave and irreparable damage to the earth. Environmental pollution consists of five basic types of pollution‚ air‚ water‚ soil‚ noise and light. Air pollution is the most harmful form of pollution in our environment. Air pollution is cause by the injurious smoke emitted by cars‚ buses‚ trucks‚ trains‚ and factories‚ namely sulphur dioxide

CHAPTER 8 Soil Compaction Soil compaction is one of the most critical components in the construction of roads‚ airfields‚ embankments‚ and foundations. The durability and stability of a structure are related to the achievement of proper soil compaction. Structural failure of roads and airfields and the damage caused by foundation settlement can often be traced back to the failure to achieve proper soil compaction. Compaction is the process of mechanically densifying a soil. Densification

Soil is one of the main elements in the environment‚ it covers most of the dry part of the Earth’s crust‚ and the content of the materials‚ including salts‚ it is very important for the green vegetation cover on earth. On the other hand soil is one of the main components of construction‚ study of soil in the workplace is one of the first steps in the beginning of the project‚ and the lack of knowledge of soil characteristics and types and how to deal with it may lead to the failure of projects in

Title L6 – Soil Permeability – Constant Head Test Introduction Permeability is measured in term of water flow through the soil in a given time. The soil permeability is a very important factor to study the behavior of soil in its natural condition with respect to water flow. The size of pore space and interconnectivity of the spaces help determine permeability‚ so shape and arrangement of grains play a role. Often the term hydraulic conductivity is used when discussing groundwater properties

Pollution Human beings have always caused some environmental pollution. Since prehistoric times‚ people have created waste. Like garbage today‚ this waste was either burned‚ tossed into waterways‚ buried‚ or dumped aboveground. However‚ the waste of early peoples was mostly food scraps and other substances that broke down easily by natural decay processes. Prehistoric populations were also much smaller and were spread out over large areas. As a result‚ pollution was less concentrated and caused
