Soil erosion is a negative affect of drought. Dry, as well as nutrient-depleted soil, is a result of insufficient rainfall, which ultimately leads to a loss of plant life. Wind and amounts of organic matter, which have decreased from lack of vegetation, are too small also contribute to soil erosion.

What happens to soil in a drought?

Drought affects soil processes in several ways, notably by directly stressing soil organisms—soil microorganisms rapidly equilibrate to the osmotic conditions (water potential) of their immediate environment—and to remain hydrated when the soil around them dries, they must accumulate solutes to retain water within ...

What causes soil erosion?

What Causes Erosion? Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
