Question

observe the distribution of earths water represented in the diagram below. according to the diagram, what percent of water that is usable by humans is considered groundwater? 99% 3.52% 30.1% 1%

Explanation:

Step1: Identify the percentage of usable - water and groundwater

The percentage of water usable by humans is 1% of all water on Earth. The percentage of groundwater in freshwater is 30.1%, and freshwater is part of the usable - water for humans.

Step2: Calculate the percentage of groundwater in usable - water

Since groundwater is 30.1% of freshwater and freshwater is part of the 1% usable water, the percentage of water that is usable by humans and is groundwater is 30.1% of the 1% usable water. But when considering the proportion within the 1% usable water, the percentage of groundwater in the water usable by humans is 30.1%.

Answer:

30.1%
