What is a disadvantage to using dams and reservoirs to supply more water quizlet?
disadvantages: causes environmental harm, and it encourages unsustainable use of water in areas water is not naturally supplied.
How is groundwater replenished?
Groundwater supplies are replenished, or recharged, by rain and snow melt that seeps down into the cracks and crevices beneath the land’s surface. In some areas of the world, people face serious water shortages because groundwater is used faster than it is naturally replenished.
What happens if the use of groundwater exceeds the rate of replenishment?
Groundwater overdraft occurs when the groundwater resources are used up more quickly than they are replenished. Groundwater overdraft can occur for a period of time without noticeable consequences, but eventually the aquifer will not be able to keep up with the rate of use as its water storage is depleted.
What is the greatest use of groundwater quizlet?
The greatest use of groundwater is irrigation, with about 68% of groundwater used in 2000 being for irrigation.
What is one disadvantage of using groundwater quizlet?
It can scar and disrupt the land surface and destroys any vegetation and habitats.
What is the best solution to groundwater depletion quizlet?
What is the best solution to groundwater depletion? Subsidize water conservation, waste less water, and limit the number of wells.
What are the three types of groundwater?
The most common groundwater source types are springs, hand-dug wells, or drilled boreholes. (But be careful, as drilled boreholes are often also called wells!).
Which is not an example of groundwater?
Explanation : Water flowing in rivers is not an example of groundwater, it is an example of surface water, which is found on the surface of the land. Groundwater is the water that is found inside the ground.
Which of the following factors is mainly responsible for declining water level in India Class 10?
Explanation: Industrialization is responsible for declining water level in India.
Which one of the following factors does not affect the distribution of groundwater?
The correct answer is Distance from the sea.
Which of the following is a ground water source quizlet?
THE MAIN SOURCE OF GROUNDWATER IS RAIN AND SNOW. About 15% of all precipitation ends up as groundwater. It is the percentage of rock’s volume that can hold water.
Which of the following is not a source of groundwater?
underground storage tank is not a major source of groundwater contamination.
What is one disadvantage of using groundwater?
The volume of groundwater in storage is decreasing in many areas of the United States in response to pumping. Groundwater depletion is primarily caused by sustained groundwater pumping. Some of the negative effects of groundwater depletion: drying up of wells.
What are the advantages and disadvantages of withdrawing groundwater?
The advantages of withdrawing groundwater include water for drinking and irrigation; availability and locality; low cost, no evaporation losses; and it is renewable. Disadvantages include aquifer depletion from over pumping, subsidence, pollution, saltwater intrusion, and reduced water flow.
What is groundwater depletion quizlet?
Terms in this set (4)
Ground water depletion is due to drying of wells, reduction od precipitation, over use in irrigating for agriculture and land subsidence. Effects on Human and other Life Forms.
Which of the following is an example of groundwater?
Answer: Groundwater is the water obtained from the surface of the Earth, beneath the ground. The water drawn from a well is an example of groundwater. Groundwater originates from rain and from melting snow and ice and is the source of water for aquifers, springs, and wells.
Which one of the following is an example of groundwater?
Which one of the following factor is mainly responsible for declining water level in India Mcq?
Which one of the following is the cause of the depletion of water table Class 7?
The two main causes of Depletion of Water Table are Deforestation and Over-pumping of groundwater.
Which of the following factors do not affect the rate of evaporation Mcq?
The evaporation rate is dependent on certain variables such as temperature, surface area, wind speed, etc. But not depend on the mixture of absolute heavy impurities.
Which of the following factor will not result in groundwater depletion?
The correct answer is Afforestation.
Why is groundwater an important source of freshwater storage 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.
Which of the following is the source of groundwater pollution Mcq?
Untreated waste from septic tanks and toxic chemicals from underground storage tanks and leaky landfills can also contaminate groundwater.
What is groundwater What are the sources of water which are fed by groundwater Class 7?
What are the sources of water which are fed by groundwater? Answer: Water found below the water table is called groundwater. The rainwater and water from other sources such as rivers and ponds seeps through the soil and fills the empty spaces and cracks deep below the ground.
What are 4 effects of groundwater depletion?
Some of the negative effects of ground-water depletion include increased pumping costs, deterioration of water quality, reduction of water in streams and lakes, or land subsidence. Such effects, while variable, happen to some degree with any ground-water use.
