It will also affect the rate of soil erosion. Some of the most unique farming landscapes of Bali are a consequence of having to cultivate steep slopes that are prone to soil erosion. Here terraces are cut in to steep slopes to retain the soil that otherwise would be easily removed due by the heavy rains. The need to cultivate such steep slopes is a consequence of population pressure and very.
This essay will discuss the reasons behind the proliferation of pollution and remedies to revert it in its previous form. Pollution has had been degrading our nature and natural environment. Various types of pollution like water and air pollution has contributed to the deformation of the biosphere. One of these forms, water pollution, which is the contamination of water bodies has contaminated.
The main reasons of soil pollution are briefly described below: (i) Pesticides: Pesticides are the chemicals which are used by farmers to protect their crops. Large amounts of pesticide in soil interfere with the soil metabolic process. Pesticides kill many non-targeted beneficial soil organisms such as earthworms. Thus, the soil becomes infertile. ADVERTISEMENTS: Organo-chlorides (like.
Soil Erosion. Cutting down on trees leads to clearance of forests and so soil erosion occurs. Exposure of the soil to the sun’s heat dries up the moisture inside the soil. Nutrients evaporate and it affects the bacteria that help to break down organic matter. Due to this, rain washes the soil surfaces and erosion takes place. Large amounts of soil wash into local streams and rivers and cause.
The burning of trees and vegetation cover also leaves the soil bare making it readily vulnerable to soil erosion. The high temperature caused by wildfires destroys almost the entire nutritive value of the soil. Economic Losses; Many have witnessed firefighters battling wildfire on TV. This could give you a rough idea of the damage wildfires can cause to the vegetation and wildlife. Wildfires.
Soil erosion - the removal of soil by the action of water or wind, compounded by poor agricultural practices, deforestation, overgrazing, and desertification. Ultraviolet (UV) radiation - a portion of the electromagnetic energy emitted by the sun and naturally filtered in the upper atmosphere by the ozone layer; UV radiation can be harmful to living organisms and has been linked to increasing.
Coastal erosion is the wearing away of land and removal of beach sediments by high winds, drainage, wave action, wave currents, and tidal currents. Coastal morphodynamics studies the erosion and sediment redistribution in coastal areas. It is caused by corrosion, hydraulic action or abrasion. For UPSC 2020 Preparation, follow BYJU'S.
Prevent soil erosion. Plants, when grown in dense, prevent soil erosion, i.e., in times of winds, the fertile top layer of soil is carried away by air. This is prevented by plants if grown around. 4. Ecological balance: Plants impart greenery to the atmosphere, they help reduce heat and prevent drying up of moisture. Thus they are environmental savvy. 5. Support rainfall. Plants and trees have.
The soil erosion is enhanced by improper surface drainage, removal of forest litter, overgrazing etc. 5. Distribution of rainfall and landscape: If the ground surface is such that rainfall distributes evenly, there is not plenty rainfall, the erosion will be less. 6. Deforestation: It is one of the major factors responsible for Soil erosion. Removal of forest cover which function as a binder.
Main reasons for river Pollution are increasing urbanisation, business industries, soil erosion, extension of agriculture on the river bank and the scarcity of water in the rivers. In the cities or coast industries are polluting rivers very much. Because, contaminated waste and polluted water from coast industries and cities industries are being carried directly into the rivers without.
