Desalinization could be a method used by which country? Sometimes, amending the soil with the addition of sand may help the drainage issue. Which of the following are possible consequences of a lower water table? Which of the following irrigation techniques is least wasteful of water? The lower, saturated level, is known as the 'zone of saturation'. Once overlying water heats to a sufficient temperature, it ___ and releases pressure on the water below. A ___ is located where the pressure surface is above the aquifer, but below the ground. When will a cone of depression stop enlarging? A high water increases hydrostatic pressure on the floor and walls of your basement, making it susceptible to leaks. There is often some seasonal change in the water table, due to rain or drought. It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity.. In some cases, lowering the water table is necessary to prevent standing water, which can cause root rot and suffocate plants. Which of the following represent the largest volume of freshwater found on Earth? How would the water table be affected if Earth were made up of uniform, permeable material? Add your answer and earn points. Which of the following is NOT a factor in determining how much or how little precipitation a region receives? The following figure shows the effect of declining water levels on two adjacent wells that are drilled to different depths on either side of a water-table pond. If the depth to water in the well on the left were, say, 10 feet during spring, it might decline to 15 feet during late summer or during a severe drought. Which of the following are possible consequences of a lower water table? (1 point) MalenaCordova is waiting for your help. Humans extract a lot of groundwater in many regions, particularly for agriculture, which can reduce groundwater levels. New questions in Biology. 1 Answer. An increase in the amount of discharge to surface water. As people pump water out of the ground, the water table can lower. Once overlying water heats to a sufficient temperature, it ___ and releases pressure on the water below. Select the two correct answers cleaner water larger aquifers saltwater intrusion land subsidence rising sea levels Which of the following activities contain hidden water … a decrease in the amount of discharge to surface water. Which of the following is a true statement about groundwater? In fact, in some places, they pump water out of the aquifer faster than nature replenishes it. What prevents water at the bottom of the underground caverns from boiling at the normal surface temperature? How does the water table change around a pumping water well? Answer Save. an increase in the amount of discharge to surface water. High water tables are a nuisance that many homeowners must face. The upper, unsaturated level, is known as the 'capillary fringe' or 'zone of aeration'. New questions in Biology. As people pump water out of the ground, the water table can lower. ... water conflicts will be a major cause of international conflict. Water in a groundwater system is stored in subsurface pore spaces and fractures. As people pump water out of the ground, the water table can lower. As people pump water out of the ground, the water table can lower. If not, you can create a channel to lower the water. Imagine how much work it would be to lift water 8 m high in the air. The pressure from the weight of overlying water causes the boiling point to increase. Urbanisation can result in more impervious ground, such as roads, which reduced the amount of water filtering through the soil (groundwater recharge). Digging a well to lower the water table affecting your basement -would this work? Which of the following are possible consequences of a lower water table? Aquitards must be present both above and below the aquifer. Imagine how much work it would be to lift water 8 m high in the air. If the water table is lowered, this exposes the upper part of the pile to aerobic conditions and rotting and decay can start to take place. choose all that apply. an increase in the amount of recharge to groundwater. The soil surface above the water table is called the unsaturated zone, where both oxygen and water fill the spaces between sediments. An artesian system is present when groundwater ___. ____ are intermittent springs that eject columns of water and steam at various time intervals. Surface is a subdued version of the surface topography. Desalination could be used by any country on the ocean, The atmosphere has the greatest _____ of the earth's hydrologic compartments. Select the two correct answers. The pressure from the weight of overlying water causes the boiling point to increase. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). Wells can "go dry" and become useless. a decrease in the amount of recharge to groundwater. Approximately _______ percent of Earth's water is freshwater. The dip in the water table below wells is called the, The largest single use of water for industrial purposes is for, Obtaining usable freshwater by processing seawater is, aquifers are porous underground geological formations from which water can be extracted, Groundwater recharge in most areas of the U.S is just barley keeping up with the rate of water withdrawal, are areas known for receiving little precipitation, Wetlands are important for the infiltration of water into aquifers, alter rainfall patterns and increase runoff, Of all world's fresh water, nearly ___ percent is tied up in glaciers, ice caps, and snowfields, The total amount of water taken from a lake, river, or aquifer for any purpose is known as.
