Answer Text:
Significance of Hydrological Cycle
Positive
1. Provides water to man from precipitation and underground water.
2. Provides rain to man who is useful in agriculture.
3. Atmospheric water is important in regulating heat loss from the earth by absorbing terrestrial radiation
and reflecting it back to the earth keeping the lower atmosphere warm.

Negative
1. May lead to shortage of water when evaporation rate exceeds precipitation.
2. May lead to decreased agricultural production as a result of excessive evaporation causing weathering of crops.
3. May lead to flooding when excessive evaporation cause increased rainfall.
4. May lead to shortage of rainfall if there is less evaporation due to low temperature.
