Question

Hydrosphere in point Wise

Answer 1

HEYAA FOLK,



1) Ocean waters and waters trapped in the pore spaces of sediments make up most of the present-day hydrosphere...

2) The total mass of water in the oceans equals about 50 percent of the mass of sedimentary rocks now in existence and about 5 percent of the mass of Earth’s crust as a whole....

3) Deep and shallow ground waters constitute a small percentage of the total water locked in the pores of sedimentary rocks—on the order of 3 to 15 percent....

4) The amount of water in the atmosphere at any one time is trivial, equivalent to roughly 13,000 cubic km (about 3,100 cubic miles) of liquid water, or about 0.001 percent of the total at Earth’s surface....

5) At present, ice locks up a little more than 2 percent of Earth’s water and may have accounted for as much as 3 percent or more during the height of the glaciations of the Pleistocene Epoch (2.6 million to 11,700 years ago).....



hope it helps you!!!
