Answer 2

Answer:

Deserts cover 1/5 of the worlds land. Over 1 billion people try to make a living out of the desert soils. These soils are dry, getting less than 10 inches of rain a year, and often are not very high in organic matter. Deserts can be very hot, or very cold. Even though it is dry, it does not mean that there is nothing living. After a rainfall, the entire desert blooms. These soils can support agriculture, but often need to be irrigated with water brought in from elsewhere. This can cause salinization. Semi-arid regions of the world are also becoming less agriculturally productive, and turning into deserts, which is caused by human activities.
