Ohene Akuoko 10/24/12 Soil and Environment Classification of Soil based on Sedimentation Rates Introduction Soil is a naturally occurring substance covering the upper level of Earth’s Continental Crust which sits upon Earth’s highest layer of geological area the lithosphere. Soil is actually nothing more but the remnants of the Earth’s Mountains and the life that has lived on this planet through the natural process of erosion and time on Earth. A good soil is said to be composed of 5 % organic

SOIL POLLUTION INTRODUCTION Soil is the thin layer of organic and inorganic materials that covers the Earth’s rocky surface. The organic portion‚ which is derived from the decayed remains of plants and animals‚ is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments‚ was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient

Soil Degradation The damaging process of soil particles being moved and cycled by water or wind is known as erosion. Soil erosion can occur anytime soil is bare or exposed and naturally removed by wind or water. This form of soil degradation is a natural process but it further elevated by human activity. Human disturbances of the soil allow for this process to happen more rapidly under natural conditions. According to the University of Michigan‚ whose geologist conducted a study‚ human actions

Your task is to prepare a 300 word paper on what your vision of work in the future and what skills you will need to succeed in the workplace. Questions to address in the paper: What is the role of technology? Is the role different than of your view of today’s technology role? How does uncertainty impact your ability to plan for the future work? Visions of the future are latent with personal bias of experience. You understanding of the future will be unique and very different from your classmate’s

A Move to a Better Life I always ask the question to myself‚ what would come of me if I would have stayed and lived in my “hometown”‚ the city of Long Beach for the entirety of my juvenile life. The populated city is north of San Diego and about twenty miles south of the city of Los Angeles. Common in most towns or cities anywhere in the world‚ there is what’s known as a friendly side of town and a bad‚ sketchy‚ or ghetto side of town. In Long Beach it is no different with it having a well-known

defined as soil. Soils come in an almost infinite variety of vertical structures and textures. Most soils are hundreds of years old and change very slowly. The work ability of the soil is the ease in which a soil can be cultivated and is determined by the soil texture. There are distinct layers of soil that are not always visible to eye but are made up of different horizons. O horizon/Humus is the decomposing plant matter. A Horizon/Topsoil is the mixed humus and leached mineral soil. E Horizon/

300 and America “Freedom isn’t free at all‚ that it comes with the highest of costs. The cost of blood.” These words were spoken by Queen Gorgo‚ wife of King Leonidas‚ in the movie 300. She speaks one of the basic philosophies of the Spartan nation‚ and even though they lived thousands of years ago‚ their principles still impact America today. Most influential movies are a product of the current events happening at the time‚ and 300 is not an exception. There was a distinct significance in the

Soil Mechanics Soil is the most misunderstood term in the field. The problem arises in the reasons for which different groups or professions study soils. Soil scientists are interested in soils as a medium for plant growth. So soil scientists focus on the organic rich part of the soils horizon and refer to the sediments below the weathered zone as parent material. Classification is based on physical‚ chemical‚ and biological properties that can be observed and measured. Soils engineers think

Types of Soil & Their Uses Soil is a complex system of organic and inorganic matter that directly and indirectly supports plant and animal life. It is comprised of minerals‚ nutrients‚ water‚ microorganisms and decomposed living matter that provide the essential elements required to sustain growth. The soils of different geographical areas differ in chemical makeup‚ structure‚ pH value‚ texture and color. Soil makes the basis of the ecosystem and performs functions essential for the survival
