Erosion- movement of soil from one area to another Salinization- the salinity of soil increases over time due to poor irrigation and soil management practices Desertification- the conversion of productive land into unfertile desert Shelterbelts- rows of trees planted to reduce erosion from wind Agroforestry- simultaneously growing trees and other crops to improve

What Is Soil Pollution? Soil pollution comprises the toxic waste of soils with resources‚ mostly chemicals that are out of place or are present at concentrations advanced than normal which may have unpleasant effects on humans or other organisms. However‚ soil pollution is also caused by resources other than the undeviating addition of man-made chemicals such as undeveloped runoff waters‚ industrial waste materials‚ acidic precipitates‚ and radioactive clash. Both organic and inorganic contaminants

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

geographical issues affecting the area. Human or natural forces can affect geographical issues. One of these issues includes erosion. Erosion is one of the biggest geographical issues‚ which is the wearing down of different materials‚ such as rock‚ soil and sand. Some of the few management strategies used to provide a better environment are sand dunes and the sea bee wall. Erosion is the wearing down of different materials caused by natural forces such as long shore drift‚ waves and tides. These forces

Before looking at river landforms it is important to understand the more general role of rivers and to develop an awareness of the processes at work within rivers. It is through this knowledge that we will better undertand the processes at work in the geomorphology of the drainage basin. The role of rivers can be understood in very simple terms. The river’s role is to balance its load and transport it to the ocean. But this this idea of rivers as merely transporting weathered material to the ocean

regions of the Himalayan foothills ultimately leads to major erosion of the land. When trees are cut off‚ the land becomes bare and unprotected. This makes the earth vulnerable towards wind‚ water‚ or glaciers to erode the soil and earth. Another way of deforesting the land is by the use of fire. When people burn down forests‚ the fire may be uncontrollable‚ and it will destroy even more natural vegetation. This also encourages erosion of the land‚ because there is no vegetation cover to protect

Coastal areas can be protected from the effects of natural processes‚ for example the effects of erosion‚ deposition‚ transportation‚ weathering and mass movement. The most problematic of these is erosion. There are three types of erosion: hydraulic action‚ abrasion and attrition which all contribute together to erode cliffs‚ causing the coastline to be vulnerable and weaker. The cause of erosion can then lead to mass movement for example rock fall and slumping which can affect the coastline greatly

The purpose of this website is to make Canadians aware about the fresh water available in Canada and to guide them to preserve it. This website tells almost everything about water present in Canada such as nature of water‚ water policy legislation‚ the water management‚ and the water culture. This website tells us

mentioned above. Its current height is now stated at 3‚753 meters making it the tallest mountain in Australasia. The mountain itself has been formed by three main geological processes; one internal: tectonic uplifting and 2 external: weathering and erosion. Internal: 1. Tectonic Uplifting Mt. Cook was formed by the internal process of orgenic tectonic uplifting‚ where two plates collide and one plate increases in elevation and the opposite plate decreases. However Mt. Cook formed differently

Post-glaciation‚ a corrie may be filled with a tarn. This is water that has been collected in the hollow; it is dammed by the rock lip. Over-deepened basin caused by erosion due to rotational flow.
