Which type of well occurs when a portion of an aquifer becomes pressurized to the point that it sends water back out to the surface of the soil?
An artesian well occurs when a portion of an aquifer is trapped between impermeable layers causing it to become pressurized. When a well is drilled into the confined aquifer, water is forced to rise to the surface without the need for pumping.
What type of well occurs when a portion of an aquifer becomes pressurized to the point that it sends water back out to the surface of the soil?
An artesian well occurs when a portion of an aquifer is confined between impermeable layers and becomes pressurized, causing water to flow naturally to the surface without the need for pumping. This happens when a downward-sloping aquifer is trapped between two impermeable layers, creating enough pressure for the water to rise above the level of the aquifer.
The point on the earths surface closest to the origin of an earthquake is called?
The point on the earth's surface closest to the origin of an earthquake is called the epicenter. This is where the seismic waves generated by the earthquake first reach the surface.
At any point on earths surface its height above sea level is called what?
The height above sea level at any point on Earth's surface is referred to as the elevation or altitude.
New water that enters an aquifer from the surface is called?
There are a number of potential causes, depending on the (1) surface topography, (2) the hydraulic head of the groundwater within the aquifer, (3) the hydrogeology of the aquifer and the (4) potential for suctions to occur in the partially saturated near surface zone (vadose zone) due to evapotranspiration. 1. If the strata or soil layers that compose the aquifer intersect the surface (for example where a valley has been cut down into the land surface by a river or glacier), then a spring will form at this point. 2 & 3. Confined aquifers are those where there are impermeable layers above and below them which restrict the vertical flow of water. If the aquifer recharge zone is high in a hill or mountain range and the aquifer flows down towards a low lying point in a valley there will be a very large change in hydraulic head. However as the water in the aquifer is confined this leads to a build up in pressure (as the water level can't rise to equalise the pressure). Any changes in the geology of the rocks above the aquifer that may increase it's permeability (whether that be a change in rock or soil type or structural features such as fractures due to faulting or jointing) will act as a flow path to the surface which the water under pressure will follow. These cases where water is forced to the surface against the force of gravity due to large hydraulic head levels are known as "artesian conditions". 4. Evaporation of water from the surface of the earth or the removal and evaporation of water from soils by plants is collectively known as evapotranspiration. As water is removed this creates a suction or negative pore pressure within the pore spaces of the soil near the surface. Which in turn will act to draw water upwards towards the surface.
What is the point on earths surface directly above an earths focus?
The epicenter
Which point on earths surface experiences night for 24 hours every day?
There is no point on the earths surface that experiences night for 24 hours every day.
What is a fixed place on the earths surface?
reference point
What is the earth point on earths surface directly of the surface of the earthquake?
This is known as the epicentre.
Point on Earths surface directly above an earthquakes starting point?
Epicenter
What is the farthest point on the south of earths surface?
the south pole
What is the point on earths surface where an earthquake energy is received?
epicenter
What is the point on earths surface directly over the earthquake?
The term describing this point is "epicentre"
What do we call the point beneath earths surface where the earthquake originates?
The point beneath the earth's surface where an earthquake originates is called the hypocenter.
What is the farthest point south o the earths surface?
south pole
