It is called "Aquifer"
Both Specific retention and specific yield relate to the ratio of the volume of water (in a permeable unit of rock and/or sediment) to the total volume of the rock and/or sediment, as it relates to gravity. Specific retention is the ratio of the volume of water that is RETAINED against the pull of gravity, ...where-as specific yield is the ratio of the volume of water that is EXPELLED (yielded) against the pull of gravity. Again, ...both as a ratio to the total volume of the rock and/or sediment.
A rock could float if its density is less than that of water, as is the rock pumice, or if it is shaped in a manner that would displace an amount of water to sufficiently cause it to float when carefully placed in water.
hydrochloric acid + calcium carbonate ▬▬► calcium chloride + carbon dioxide + water
moisture is lacking and organic acids are scarce
Measuring the Mass of a Rock You use a scale to weigh the rock, next you put a certain amount of water in a container, next you add the rock to the water and subtract the current water level from the original water level, the weight of the rock divided by the amount of water it displaced is the mass. ---------------------------------------------------------------------------------------------------------------------------------------------- The mass of a rock sample is measured placing the sample on an adequate balance ! The unit of mass in SI is the kilogram (kg) and the derived unit for density is kg/m3 (g/cm3 is also accepted). Do not confuse mass with weight.
Fill a graduated cylinder full of water, than drop a rock inside. The amount that the water rises will determine the volume of the rock. Amount of water level increase=volume of rock.

Things sink in water when their density is greater than that of water. Water has a density of 1000 kg/m3, rock exceeds this by a significant amount. The principle at work is that things sink if they water tey displace weighs less than the mass of the object.
place the rock in a large container that is fillec to the brim with water, making sure you know how much water you put in. Place a tray underneath (or something similar) and place the rock in. Wait until the water stops moving, then measure the amount of water on the tray. The amount of water in the tray is the volume of the rock. E.g. the water in the tray was 20ml, so the volume of the rock is 20cm3.
Fill the cylinder about half way with water and measure the amount. Then drop the rock in and measure the amount of water. Now subtract no rock from rock in and that will give you the amount of volume displaced from the rock.

Place a rock in a container, add water, and record the volume.Pour an unknown amount of water into a glass container, add the rock, and note the water level; the unknown amount of water plus the weight of the rock is the volume of the rock.Pour a known amount of water into a glass container, add the rock, and note the new water level; the difference in water levels is the volume of the rock.Water displacement will not work.
The volume of the rock is the amount of water it displaces, 250ml. Considering that 1ml of water has a mass of 1 mg, the mass of the rock is 5.63 x 250gm = 1,407.5mg.

i have drillde 1100 feet borewell last year, I only got 1/2 inch water at 360feet.Now from past 20 days i witness improvement in the water yield. my borewell is located in low lying area geographicaly.. Will there be any improvement in the yield.
the temperature of the rock will rise faster
