Angela and her sister visited a village and noticed that steps were cut into some slopes and grass was planted on them.The village chief mentioned that the grass was planted to help prevent soil erosion during heavy rains. Soil erosion occurs when the layers of soil wear away due to strong winds, hard rains and flowing water.How do the grasses help prevent soil erosions on the slopes?The ___________ of the grass hold the soil together. Thus, even if rainwater flows down the slopes, the soil will not get washed away.

Mention any two agricultural techniques that can help to prevent soil erosion.

What is one major cause of soil erosion? Group of answer choicesPlanting treesHeavy rainfallBuilding housesWalking on paths

----------------- is a gradual downward movement of wet soil along the slopes under theinfluence of gravity.

Because they can absorb more rainwater, resulting in less surface runoff and sheet erosion, -grained soils erode at a slower rate than -grained soils. (Enter only one word per blank.)

Plants serve a dual purpose in the erosion process. They anchor down soil which helps prevent erosion, but in contrast, they can also cause erosion. Which of the following best describes a process by which they can cause erosion?APlant can grow in the soil between rocks, loosening and cracking the material.BRoots can absorb water from the soil and transport it to the rest of the plant.CPlants and roots removed to clear land for construction or farming.DSoil picked up by the wind and carried as dust for several miles.
