Question

Reservoirs, lakes, ponds, rivers and canals contain how much percentage of freshwater?
A.77.2$\%$
B.22.4$\%$
C.0.36$\%$
D.30.3$\%$

Answer 1

Hint: About 97.5 percent of the water accessible on Earth is found as salt water in seas and oceans, and is not immediately usable. Freshwater makes up about 2.5 percent of the world's total water resources. The vast majority of it is ice-covered mountains and ice caps at both poles. We have access to a limited amount of fresh water as a renewable resource through the water cycle, but its distribution is unequal.

Complete answer: Any naturally occurring water with minimal amounts of dissolved salts and other total dissolved solids is referred to as fresh water (or freshwater). Though saltwater and brackish water are officially excluded, non-salty mineral-rich waters such as chalybeate springs are included. Water in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rains, rivers, streams, and groundwater stored in subsurface aquifers are all examples of freshwater. Water is necessary for all living beings to survive. Many species can survive in salt water, but most higher plants and animals require fresh water to survive. The ocean is the world's greatest water reserve, containing 97.3 percent of all water on the planet. Glaciers and polar ice, which hold little over 2$\%$ of the accessible fresh water, are the second largest reservoirs of water. Fresh water is found in 0.36 percent of reservoirs, lakes, ponds, rivers, and canals.
As a result, option C is the proper response.

Note:
Fresh water is not always potable water, or water that can be consumed. Without treatment, much of the world's fresh water (including surface and groundwater) is unfit for human consumption. Fresh water may readily become contaminated as a result of human activity or natural processes such as erosion.
