Question
- where is most fresh water that is available for human consumption found?
at the surface
frozen in ice
in the oceans
groundwater
- how does water get beneath the earths surface after it rains?
it percolates through the soil
it stays in rivers and streams
it rains underneath the surface as well
underground canals
Brief Explanations
- Oceans contain salt - water, not fresh water. Most of the fresh water available for human consumption is groundwater. Groundwater is water that is found beneath the Earth's surface in soil pores and fractures in rock. Surface water (like in rivers and lakes) is also used, but groundwater is a major source. Ice (glaciers etc.) contains a large amount of fresh water but it is not easily accessible for daily human consumption compared to groundwater.
- When it rains, water can percolate through the soil. This process is called infiltration. Water that stays in rivers and streams is surface water, not water beneath the Earth's surface. Rain does not fall underneath the surface. Underground canals are man - made and not a natural way for water to get beneath the surface after rain (the natural way is percolation through soil).
