Aquatic pollution is a worldwide problem that occurs every day in all bodies of water. Adedeji and Adetunji (2011) refer to aquatic pollution as an addition of hazardous substances‚ called pollutants‚ to these bodies of water. These pollutants are harmful to humans‚ but more importantly‚ they are extremely harmful to marine life due to the contamination of their habitats. Unfortunately‚ this occurrence is not uncommon‚ and it is mainly the result of human activities. Most pollution is derived from

SOilIntroduction Soil plays a vital role in our ability to cultivate crops. Throughout human history‚ our relationship with the soil has affected our ability to cultivate crops and influenced the success of civilizations. This relationship between humans‚ the earth‚ and food sources affirms soil as the foundation of agriculture. Soil testing is necessary for knowledge of characteristic of the soil‚ quantity of fertilizer is needed so that fertilizers are used only as needed‚ not too less or too

Soil Porosity and Permeability GEO 101 LAB – Earth Science July 26‚ 2014 Soil Porosity and Permeability The focus of week three’s lab in Earth Science is to figure out the porosity and permeability of four different soil types: gravel‚ sand‚ potting soil‚ and soil from my back yard. This lab is designed to look at the porosity and permeability of these four soil samples. Porosity is basically the measure of how much of the soil volume is open space. Permeability is the measurement of how long

What is Soil? Soil is the surface of the earth’s crust where plants have their roots and where many small animals make their home. It is also a result of the breakdown of rocks. Formation of Soil Soil is formed when rocks break down into very small particles by various processes such as weathering. There are two types of weathering: Physical Weathering and Chemical Weathering. Physical Weathering arises from the heating and cooling‚ the wetting and drying‚ and the freezing and

SOIL EROSION Janeen Uy I BS MANAGEMENT ES 10 J Submitted to: Dr. Severino Salmo III March 8‚ 2012 Soil is found on the Earth’s crust and formed through weathering and decay of organisms. It may be considered dirt to a lot of people but it is highly an important tool for our survival. The soil holds the roots of the plants where nutrients are stored. It is important since it enables the soil to store and regulate the flow of water‚ filters the pollutants and improves the soil’s quality

overview of the topic about the causes and effects of air pollution to our environment. The term air pollution is a mixture of natural and manmade substances in the air we breath such as fine particles produced by the burning of fossils fuel ground level ozone‚ which is a reactive form of oxygen that is a primary component of urban smog and noxious gases such as sulfur dioxide‚ nitrogen oxides‚ carbon monoxide‚ and chemical vapors. The health effects of air pollution have been reported in research

The soil is an important part of the landscape and contributes to determine the way in which natural vegetation‚ crops and human settlements are distributed on the territory. But the importance of the soil is mainly related to its double role as a reserve of nutritional elements and water and mechanical support (how would plants be able to stand upright if they did not have the soil to put their roots in?) for vegetation‚ leading to the creation of forests and protected areas. A direct observation
