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

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

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

640 RESESEARCH TOPIC: EVALUATION ON POPULATION GROWTH TO LAND POLLUTION IN DAR ES SALAAM URBAN CITY. The concept of land pollution by government is so wide and complex because it has been conceptualized differently by different actors such as organization‚ government itself and private sectors through over time. This includes responsibility of the government and non-government actors about the cause‚ effects and solution to land pollution problem. All these issues have been written and discussed

Impact of Pollution The environment is a part of our daily lives yet most people do not consider the impact that their actions have on the environment. People interact with and depend on different aspects of the environment from the air to water and land. There are relationships between actions that we make and the environment‚ the most obvious one being pollution. The lasting influence we have on our surroundings may not be immediately apparent but future generations will have to live with

Changes in land use and management can affect soil characteristics as well as soil quality. The term soil quality can be defined as the overall activity of a soil within an ecosystem that preserves biological activity and environmental quality‚ thus promoting plant and animal health (Doran et al. 1994). Alterations in soil properties and processes can affect functions that soils perform in the environment‚ which in turn influence patterns of plant growth (Ahuja 2003). Changes in land use influence

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

Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Air pollution has always accompanied civilizations. Pollution started from the prehistoric times when man created
