Question

What affect will be seen on agriculture,plants, animals, microbes and humans if the usable soil layer gets eroded?​

Answer 1

Answer:

Erosion occurs when soil is left exposed to rain drop or wind energy. The raindrops hitting a hectare of land in the New York State region of the United States provide the energy equivalent of 60,000 kcal (250 × 106 joules) per year with about 1000 mm of rainfall [13]. This 60,000 kcal roughly equals the energy in eight liters of gasoline. The raindrops hitting soil loosen the soil particles and with even a 2% slope start the movement of the soil downhill. Sheet erosion is the dominant type of erosion [3,14]. The impact of soil erosion is intensified on all sloping land, where with each degree of slope more of the surface soil is carried away as the water moves downhill into valleys and streams.
