Earth's Freshwater


2.1 How does water move from the atmosphere to the ground and back?

This schematic of the hydrological cycle illustrates how elements can be grouped as part of a conceptual model that has emerged from the new discipline of ecohydrology, which stresses the important relationships and pathways shared among hydrological and ecological systems Zalewski et al.

Earth's Freshwater

Most fresh water is trapped as ice in the vast glaciers and ice sheets of Greenland. A storage location for water such as an ocean, glacier, pond, or even the atmosphere is known as a reservoir. A water molecule may pass through a reservoir very quickly or may remain for much longer. The amount of time a molecule stays in a reservoir is known as its residence time. Because of the unique properties of water, water molecules can cycle through almost anywhere on Earth. The water molecule found in your glass of water today could have erupted from a volcano early in Earth history. In the intervening billions of years, the molecule probably spent time in a glacier or far below the ground.

Water is also highly visible in Canada: probably no country in the world has as much of its surface area covered by freshwater as does Canada. Of particular note are the Great Lakes. This set of lakes, which is shared with the United States, makes up the largest surface area of freshwater found in one place anywhere in the world. Water is used in the resources and energy industries. A watershed is an area that drains all precipitation received as a runoff or base flow groundwater sources into a particular river or set of rivers. The easiest way to describe the network of rivers and lakes on a small-scale map is to show the watersheds. In Canada, there is a detailed hierarchy of watersheds, ranging from the largest drainage into oceans and their equivalents , down to the smallest ramification.


In photographs taken from space, we can see that our planet has more water than land. It is unexpected and somewhat inconceivable that less than three percent of Earth's water is fresh water. According to the U. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water.

It is shown that even though geoid highs and lows do not generally correspond to the locations of the continents and oceans, the average land-water distribution.

Water also exists below land surface and as water vapor in the air. Water is a finite source. The bottled water that is consumed today might possibly be the same water that once trickled down the back of a wooly mammoth.

 Если Стратмор не забил тревогу, то зачем тревожиться. - Да в шифровалке темно как в аду, черт тебя дери. - Может быть, Стратмор решил посмотреть на звезды. - Джабба, мне не до шуток. - Ну хорошо, - сказал он, приподнимаясь на локтях.  - Может быть, у них закоротило генератор.

Она остановилась и снова начала вглядываться в глубь помещения Третьего узла. В полумраке ей удалось различить руку Хейла. Но она не была прижата к боку, как раньше, и его тело уже не опутывали веревки. Теперь рука была закинута за голову, следовательно, Хейл лежал на спине. Неужели высвободился. Однако тот не подавал никаких признаков жизни.

 Может быть, он и жил. - Вовсе. Пересек границу неделю. - Наверное, хотел сюда переехать, - сухо предположил Беккер. - Да. Первая неделя оказалась последней.
