What is a groundwater system?
"Groundwater flow is the movement of water that travels and seeps through soil and rock underground. Stored in cavities and geologic pores of the earth's crust, confined groundwater is under a great deal of pressure. Its upper part is lower than the material in which it is confined. Unconfined groundwater is the term for an aquifer with an exposed water surface."
What are two results of overuse of groundwater?
Two results of overuse of groundwater are depletion of aquifers, leading to lowered water tables and potential land subsidence, and saltwater intrusion into freshwater sources, making the water undrinkable.
Why is it important to know the depth if an aquifer before drilling a well?
Knowing the depth of an aquifer before drilling a well is important because it allows drillers to estimate the cost and time required for drilling operations. It also helps in determining the appropriate drilling equipment and technique to use for optimal results. Additionally, knowledge of the aquifer's depth aids in determining the sustainability of water extraction and minimizing the risk of depleting the aquifer.
Applications of resistivity method for groundwater?
Electrical resistivity method is an excellent tool for groundwater exploration.Current is injected in ground through two electrodes and resultant potential is measured through another pair of electrodes. These electrode are placed on ground at predefined locations .Wenner and Schlumberger are the most widely used configuration for placing the electrodes.Sounding with Schlumberger configuration is carried out for groundwater investigation.The data is then interpreted with available software and the results are in the form of resistivity and the thickness of different layers.These can be gainfully correalated with available geological data and thus site for dugwell/tubewell can be finalised.The sea water intrusion,factories polluting discharge also can be successfully delineated with resistivity method
What of the following glacial features results from deposition a moraine?
Glacial moraine could dam and prevent glacial meltwater from escaping. Glacial lakes usually form behind the moraine as the thawing glacier retreats.

How would describe the formation of aquifer and artesian well cavern?
Aquifers are formed through the accumulation of water in porous rock or sediment layers, usually beneath the Earth's surface, where water infiltrates through soil and rock formations. An artesian well occurs when water under pressure in an aquifer rises to the surface naturally without the need for pumping, often due to a confining layer above the aquifer that creates pressure. Caverns can form within aquifers when groundwater dissolves soluble rock, such as limestone, creating voids that can expand over time. This interplay of water movement, pressure, and geological processes results in the unique characteristics of aquifers and artesian wells.
Why is ground water free from pollution?
Groundwater is as prone to contamination as surface water. Groundwater contamination results from the infiltration of spills at the surface, leachate from tanks. pipelines and buried waste. Groundwater may also be contaminated by naturally occurring salts, metals, organics and gases in the soil.

Which rock type is most easily dissolved by groundwater?
Limestone is the rock type most easily dissolved by groundwater, due to its high solubility in acidic water. This process results in the formation of features such as caves, sinkholes, and underground streams.
Is organic fertilizer heathy for plants?
It is healthy for plants and for the environment too because it keeps chemicals from ordinary fertilizers from getting into groundwater. That's important because we drink groundwater and water from streams. However, it takes longer to see results of organic fertilizers.

Kay has written: 'Estimated water withdrawals, water use, and water consumption in Illinois, Indiana, Iowa, Kentucky, Michigan, Missouri, and Wisconsin, 1950-95' -- subject(s): Water consumption, Water use, Water withdrawals 'Geohydrology and ground-water quality in the vicinity of a ground-water-contamination site in Rockford, Illinois' -- subject(s): Groundwater, Hydrogeology, Pollution, Quality 'Hydrogeology and results of aquifer tests in the vicinity of a hazardous-waste disposal site near Byron, Illinois' -- subject(s): Aquifers, Groundwater, Hazardous waste sites
Why water vaporize at 70 degree Celsius?
70 degree Celsius is qiute a high temperature. in this temperature, the water molecules starts escaping which results in the vapourisation of water.
What is the meaning of UFE results?
The term UFE, medically, refers to Uterine Fibroid Embolization, a procedure typically performed by a radiologist. The results determine whether or not too much blood is flowing to a woman's fibroids.
