Which is a result of loss of top soil? check all that apply.

loss in soil fertility
loss in water
poor crop production
hardened soil surface
deposition of aggregate

Loss of soil top can result in deposition of aggregate.

Explanation:

Soil erosion or loss of soil top occurs due to deforestation, use of chemicals in agriculture and overgrazing of crops. Researches have shown that in the last 150 years massive amount of soil has been lost from the Earth’s surface. It has affected the quality of soil and its fertility along with degradation of nutrients from the soil and pollution.

Due to soil loss, aggregates like- fertilizers, pesticides along with the soil from the land are deposited in the water by rain, waterways and streams. This deposition of wastes and chemicals pollutes and sediments the water by damaging it and the local residents.  

The answers are, Loss in soil fertility, loss in water, poor crop production, and hardened soil surface. Basically the first four :)
