Answer to Problem 1FQ

The percentage of liquid freshwater that flows in rivers is 0.006%.

Explanation of Solution

The water that is used by the human population is freshwater. Freshwater is a precious and limited natural resource. About 69.56% of freshwater occurs in the glaciers, which is not available for daily human needs. The subsurface water or groundwater contributes about 30.10% of freshwater. The rivers consist of 0.006%; swamps, marshes, and wetlands 0.03%, soil moisture 0.05%, atmosphere 0.04%, and freshwater lakes 0.25%.
