'Many thanks for getting back to me like you said you would. I just hopped on to send you an email to ask you about it and am pleasantly surprised that you beat me to it! It's not often these days that someone actually remembers to keep their word and actually do what they said they would in business. As someone in business myself (albeit only a small business) I appreciate your time, effort and thoughtfulness.' - Linda. 'Thanks for the advice, and for getting back to me so quickly.
The Earth contains four spheres: hydrosphere, atmosphere, geosphere, and biosphere . The hydrosphere is a dynamic mass of water that is continually on the move. It represents â¦water that is at or near Earth's surface. The hydrosphere comprises 71 percent of Earth's surface and 97 percent of Earth's water. Freshwater, underground water, streams, lakes, ice, and glaciers are included in the hydrosphere. The atmosphere is the Earth's gaseous envelope. It is thin and tenuous and it protects us from the sun's heat and ultraviolent radiation.
Groundwater makes up about twenty percent of the world's fresh water supply, which is about 0.61% of the entire world's water, including oceans and permanent ice. Global groundwater storage is roughly equal to the total amount of freshwater stored in the snow and ice pack, including the north and south poles.
