What does it mean when the water table is near the earths surface?
The water table is the level at which the submarine pressure is far from atmospheric pressure. It may be conveniently visualized as the 'surface' of the subsurface materials that are saturated with groundwater in a given vicinity. However, saturated conditions may extend above the water table as surface tension holds water in some pores below atmospheric pressure.[1] Individual points on the water table are typically measured as the elevation that the water rises to in a well screened in the shallow groundwater.The groundwater may be from infiltrating precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths water fills in more of the pore spaces in the soils, until the zone of saturation is reached. In permeable or porous materials, such as sands and well fractured bedrock, the water table forms a relatively horizontal plane. Below the water table, in the phreatic zone, permeable units that yield groundwater are called aquifers. The ability of the aquifer to store groundwater is dependent on the primary and secondary porosity and permeability of the rock or soil. In soil that are less permeable, such as tight bedrock formations and historic lakebed deposits, the water table may be more difficult to define.The water table should not be confused with the water level in a deeper well. If a deeper aquifer has a lower permeable unit that confines the upward flow, then the water level in a well screened in this aquifer may rise to a level that is greater or less than the elevation of the actual water table. The elevation of the water in this deeper well is dependent upon the pressure in the deeper aquifer and is referred to as the potentiometric surface, not the water table.
The column on the far left of the periodic table contains the?
Most reactive metals
Where is the safest place to be during an earthquake?
Hide in the lowest possible place in your house if your house is not low at all or your in a flat go as far away from any building you can. -----------------------------------INCORRECT ANSWER ABOVE.---------------------------------- Do not exit the building. Ever. Falling objects will crush you, no doubt. Always hide either standing under a door frame, or NEXT to a table. (Do not go in your basement, as the earth itself may swallow you. Stay on your main floor.) Many people mistake going under a table. If you go under a table, the roof will fall and crush you. Next to a table... The roof will crush the table, and this will force the table to become diagonal. The space between the table and the floor is called the Triangle of Life. And, I repeat. NEVER go under a table. It will kill you.
What is the difference between arid and semiarid climate zones?
The difference between Arid and Deserts is pretty simple. It all boils down to how much precipitation the area gets. on average a desert area will receive no more then 5 inches of water a year. sometimes less. an arid area will receive far less water. if any at all.
How far can lighting strike?
i guess it all depends on were it is directly at and lighting can go until it hits the ground
How far is the water table?
From solid ground it could be a matter of inches, or several miles.
Cold temperatures increase or decrease the water table?
Heat would dry the earth. If the water table is down far enough it would not be affected.
Why can the water in a well far from a source of pollution be polluted?
The water table was polluted by the pollution source due to rainfall or ground water contamination near the pollution site.
What is water trapped under ground called?
They are called groundwater. Far as I know, there is no specific name separating ground water in shallow water table and the ground water in confined aquifer. So you might have to called by the full description "groundwater in confined aquifer layer". Aquifer is the specifics name for porous rock and earth media in the question.
Were on the periodic table is kyrpton found?
Far right, 3rd down.
What is water that soaks into the ground?
The water that soaks in ground called as ground water .
What is the weakness of regirock?
Metal, grass, water and ground as far as i now
How far must you drill to create a well?
For a water well, until you reach the water table. The depth will vary.
Were do worms live?
In the ground but when it starts to get close to winter they move far down in the dirt
How far to ground for the splits?
As a cheerleader there is low limit to how far you go down. If u stretch and practice it everyday then u will be on your way to your splits.
