Briefly describe the distribution of water resources on Earth.
Answers
Explanation:
The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.
All one needs to do is study rainfall maps to appreciate how uneven the distribution of water really is. The white areas on the map below had annual rainfall under 400 mm for the last year, which makes them semi-arid or arid. And, remember, projections are for significant aridification to occur in many dry regions and for more severe rainfall events to characterize wet regions.
Answer:
The distribution of water is not uniform in both the hemispheres of earth. It is estimated the 43 % of total area covered by water lies in northern hemisphere where as the remaining 57 % lies in the southern hemisphere. About 96.5 % of total water are in the form of ocean . Rest water are present in the form of river ,lake , pond , water vapour etc.
