Percolation is the movement of water through the soil itself. Finally, as the water percolates into the deeper layers of the soil, it reaches ground water, which is water below the surface. The upper surface of this underground water is called the “water table”.
What is groundwater flow in the water cycle?
When precipitation reaches the earth’s surface, some of it will flow along the surface of the land and enter surface water like lakes, streams, and rivers, as runoff. The rest of it soaks or percolates into the soil, called recharge. … This movement of water underground is called groundwater flow.
How does water move from the atmosphere to the ground and back?
The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth’s surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.
What is groundwater and where does it come from quizlet?
Groundwater is the water stored in the pore spaces of rocks and soils underground. It is a part of the water cycle and is naturally refilled by precipitation and runoff that infiltrate the soil. It can then be pumped to your house by a well and through pipes. You just studied 51 terms!
Where does groundwater come from quizlet?
Most groundwater originates as meteoric water from precipitation in the form of rain or snow. Once the water hits the land, water from the surface seeps into the ground. The water is able to move underground through the rock and soil due to connected pore spaces.
What is the importance of groundwater quizlet?
Groundwater is an important source of freshwater, partly because it accounts for approximately 30% of the Earth’s freshwater. Groundwater is an important source of freshwater for areas that do not have access to other sources of freshwater, such as areas that are experiencing droughts.
How does groundwater affect streams?
Streams interact with groundwater in all types of landscapes. … streams gain water from inflow of groundwater through the streambed (gaining stream), streams lose water to groundwater by outflow through the streambed (losing stream), or. they do both, gaining in some reaches and losing in other reaches.
What happens when groundwater is over pumped?
Excessive pumping can lower the groundwater table, and cause wells to no longer be able to reach groundwater. … When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished. Land Subsidence. Land subsidence occurs when there is a loss of support below ground.
