How does the water table relate to the water cycle?
Fluctuations in the water table level are caused by changes in precipitation between seasons and years. During late winter and spring, when snow melts and precipitation is high, the water table rises. There is a lag, however, between when precipitation infiltrates the saturated zone and when the water table rises.
What is true regarding water table?
A water table describes the boundary between water-saturated ground and unsaturated ground. Below the water table, rocks and soil are full of water. Pockets of water existing below the water table are called aquifers. An area's water table can fluctuate as water seeps downward from the surface.
What happens to the water table if ground water is pumped out faster than it can be replaced?
If water is withdrawn from the ground at a faster rate that it is replenished, either by infiltration from the surface or from streams, then the water table can become lower, resulting in a "cone of depression" around the well.
What is groundwater and how does it relate to the water table?
water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it.
What is the water table quizlet?
The Water Table is the upper limit of under ground water. • It rises when rain falls as the pore spaces become filled. • During dry periods the level falls. 3 zones of underlying rock structure. 1) Zone of non-saturation.
Which of the following statements about the water table is false?
B. the water table is generally flat is the false statement.. Water table receives the water from surface that is filtered through soil, sediment and rocks. The source of water for water table is rain, irrigation and snow.
What is a water table quizlet?
Water table. Underground area where the earths surface is saturated.
Which of the following statement about the water table is false?
B. the water table is generally flat is the false statement.. Water table receives the water from surface that is filtered through soil, sediment and rocks. The source of water for water table is rain, irrigation and snow.
What happens to water levels when the rate of pumping is greater than the rate of infiltration?
Describe what happens to water levels when the rate of pumping is greater than the rate of infiltration. The water table drops a lot, so much that some of the shallower wells run dry.
How does the water table change around a pumping water well quizlet?
How does the water table change around a pumping water well? The water table elevation decreases.
Do lakes intersect the water table?
Some water tables intersect with lakes and rivers and are modified by them. Water tables are not flat or horizontal: they often follow the conformation of the land and are usually slightly inclined, causing groundwater to flow.
Where is the water table in a lake?
The level below which all the spaces are filled with water is called the water table. Above the water table lies the unsaturated zone.
What is the zone above the water table called quizlet?
A subsurface zone above the water table where the rock or soil may be moist but not saturated, with air occupying some or all of the pore space; also called the unsaturated zone.
Which one of the following statements about water is incorrect?
Water possesses intermolecular hydrogen bonding in the condensed phase rather than intramolecular hydrogen bonding. Therefore statement (D) is incorrect.
Which of the following statements about water molecule is true?
Answer: The true statements are: Water molecules move randomly around each other.
What happens to groundwater when the rate of inflation is less than the rate of water being pumped out of the ground?
What happens to groundwater when the rate of infiltration is less than the rate of water being pumped out of the ground? c. The water table lowers.
How can water needs be met if the rate of infiltration is lower than the rate of pumping?
In this situation, how do you think water needs can be met over the long-term? When infiltration is unable to replace groundwater as quickly as pumping removes it, the water table drops. Deeper wells could be dug to chase the table, but then the water table will just drop even further.
How does the water table change around a pumping water well the water table elevation decreases the water table elevation stays the same the water table elevation increases?
Groundwater moves over larger distances, over longer timescales. How does the water table change around a pumping water well? The water table elevation decreases.
How does the movement of groundwater relate to hydraulic gradient and hydraulic conductivity Please select all that apply?
groundwater moves more quickly down steeper slopes than down shallow slopes. for this reason, the water table is known as the hydraulic gradient. groundwater flows more rapidly through sediments having greater permeability than through materials having lower permeability. this factor is known as hydraulic conductivity.
Where water is able to enter into an aquifer is called quizlet?
the ability of rock or soil to allow water to flow through it is called permeability. Earth's surface from which water percolates down into an aquifer is called a recharge zone.
Which of the following statements about water table is false?
B. the water table is generally flat is the false statement.. Water table receives the water from surface that is filtered through soil, sediment and rocks. The source of water for water table is rain, irrigation and snow.
Which of the following statements related to water are correct water is a polar molecule?
The correct answer is Water is a nonpolar molecule. Water is a polar molecule: Water is a polar molecule. While the overall charge of the molecule is neutral, the orientation of the two positively charged hydrogens (+1 each) at one end and the negatively charged oxygen (-2) at the other end give it two poles.
Which of the following statements about the water molecule is true a water molecule is symmetrical and therefore is nonpolar?
none of the choices are correct Awater molecule is symmetrical and therefore is nonpolar: The electronegativities of hydrogen and oxygen are equal and therefore a water molecule is nonpolar: Awater molecule is asymmetric and therefore is polar: Awater molecule has two dipole moments and they cancel each other.
When groundwater is withdrawn from an unconfined aquifer by a pumping well what happens to the water table nearby?
surface the well is defined as a flowing artesian well. The zone around a well in an unconfined aquifer that is normally saturated, but becomes unsaturated as a well is pumped, leaving an area where the water table dips down to form a cone shape.
When the rate of rainfall exceeds the soil’s ability to absorb it the surplus water flows downhill in a process called?
What is a runoff? When the rate of rainfall exceeds Earth's ability to absorb it, the surplus water flows over the surface into lakes and streams.
Which of the following factors is mainly responsible for declining water level in India irrigation Industrialisation and Urbanisation overutilization?
Explanation: Industrialization is responsible for declining water level in India.
When ground water moves to the surface to become part of rivers streams and lakes it is called?
Runoff. 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.
What happens when the water table drops below sea level in aquifers near the ocean?
What happens when the water table drops below sea level in aquifers near the ocean? There is no consequence to this. In which scenario would it be easier to identify a source of the eutrophication: a river with a large watershed or a river with a small watershed?
How will the water table respond if it is a wet spring?
How will the water table respond if it is a wet spring? Water table will rise.
What is the difference between hydraulic head and hydraulic gradient?
Groundwater flows from regions of higher hydraulic head to regions of lower hydraulic head. The change in hydraulic head along a groundwater flow path is termed the hydraulic gradient. The hydraulic gradient has both a magnitude and direction.
