Where is freshwater found?
On the landscape, freshwater is stored in rivers, lakes, reservoirs, and creeks and streams. Most of the water people use everyday comes from these sources of water on the land surface.
What freshwater means?
Freshwater is water that contains only minimal quantities of dissolved salts, thus distinguishing it from sea water or brackish water. All freshwater ultimately comes from precipitation of atmospheric water vapor, reaching inland lakes, rivers, and groundwater bodies directly, or after melting of snow or ice.
Where is groundwater found?
aquifers
Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
Are all rivers freshwater?
Salt water is 97\% of all water and is found mostly in our oceans and seas. Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater.
Why are rivers freshwater?
In the beginning, the primeval seas were probably only slightly salty. But over time, as rain fell to the Earth and ran over the land, breaking up rocks and transporting their minerals to the ocean, the ocean has become saltier. Rain replenishes freshwater in rivers and streams, so they don’t taste salty.

Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
What is the main source of groundwater?
rain
Most groundwater originates as meteoric water from precipitation in the form of rain or snow. If it is not lost by evaporation, transpiration or to stream runoff, water from these sources may infiltrate into the ground.
Are Oceans freshwater?
The water in the oceans is saline (saltwater), but, what do we mean by “saline water?” Saline water contains significant amounts (referred to as “concentrations”) of dissolved salts.
Are ponds saltwater or freshwater?
Freshwater habitats include ponds, lakes, rivers, and streams, while marine habitats include the ocean and salty seas. Ponds and lakes are both stationary bodies of freshwater, with ponds being smaller than lakes. The types of life present vary within lakes and ponds.
Are glaciers freshwater?
Glacierized areas cover over 15 million square kilometers (5.8 million square miles). Glaciers store about 69 percent of the world’s fresh water. During the maximum point of the last ice age, glaciers covered about 32 percent of the total land area.
Is water underground everywhere?
Groundwater is everywhere beneath the soil surface and can be ever-present in many places if allowed to recharge. Even in dry conditions, it maintains the flow of rivers and streams by replenishing them, providing a valuable substitute for precipitation.
Which countries use groundwater?
Giordano (2009) reported that global groundwater extraction is in excess of 650 km3 per year, with India, the United States, China, Pakistan, Iran, Mexico, and Saudi Arabia collectively accounting for 75\% of this total amount. …
