Which of the following practices contributes most to soil erosion. Depletion of groundwater resources due to Over exploitation has led to many. A salinization due to improper draining of irrigated land.

As a result of erosion there is no fertile soil left to grow plants. Too many crops are grown on the land and the land gradually loses its fertility. Chemical weathering and erosion.

Activities that remove vegetation disturb the ground or allow the ground to dry are activities that increase erosion. Many feel this rule should apply to genetically modified organisms. D wind erosion of deforested lands.

Which of the following agricultural products requires the least amount of energy. Fast growing human population desertification and sold erosion all the above topsoil. Soil erosion can occur in two stages.

The best choice of plants to prevent soil erosion are herbs wild flowers and small trees. And 2 transport of detached particles by splash or flowing water. Plants prevent wind and water erosion by covering the soil and binding the soil with their roots.

Climatic Agencies Causing Erosion of Soil. Construction of roads and buildings logging mining and agricultural production have resulted in large amounts of soil erosion in the US. Ways to Prevent Soil Erosion 1.

Soil erosion by water occurs when bare-sloped soil surface is exposed to rainfall and the rainfall intensity exceeds the rate of soil intake or infiltration rate leading to soil-surface runoff. All of the above. Erosion whether it is by water wind or tillage.

Which of the following ranching practices contributes to soil erosion. And around the world. Human activities such as deforestation are the major cause of soil erosion.

Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Two things that destroy the topsoil. These are water and wind.

Which of the following actions contributes to soil erosion. The smaller soil particles are easily carried by water or wind resulting in soil erosion. Climate change and human activity like overgrazing of grasslands is leading to large areas subject to desertification where native grass cover dies out.

Which of the following agricultural products requires the least amount of energy. Human activities responsible for soil erosion are. 1 detachment of soil particles by raindrop impact splash or flowing water.

Allowing fields to remain empty and unused. Domestic animals are allowed to overgraze the land. Allowing land to lie fallow c.

Grazing more than one type of animal on the land C. Soil is directly affected by heavy rainfall rapidly running water and by wave action. Aside from desertification there is no doubt that human activities are a major cause of soil erosion in general.

Deforestation leaves large areas pf land exposed to heavy rainfall when this happens the soil becomes loose and easier to erode. Topsoil which is high in organic matter fertility and soil life is relocated elsewhere on-site where it builds up. The following human practices aid in the acceleration of the soil erosion process.

Tree roots hold soil particles together and when human human population encroaches the forest and clears it land is left bare exposing it to erosion. Farmers plant trees and grass to cover and bind the soil. Soil erosion is wearing away of soil particles due to the action of erosion agents such as moving water ice and wind.

Regions with very heavy and frequent rainfall face a large amount of soil loss.
