What substance are the lines on a football field marked with?
I'm not sure about today's marking substance, but for many years, in the old days, it was nothing more than POWDERED CHALK, which I think is Calcium Carbonate. Today, some are using synthetic materials, or even spray paint.
Why will chalk dust on a plastic sheet placed over a bar magnet not show the shape of the magnetic field?
Chalk dust (calcium carbonate) is not magnetisable.
If Jacques Cousteau recognized that coral reef exoskeletons were composed of calcium carbonate dissolved CO2 production then why not marine biologists of 2014?
Jacques-Yves Cousteau recognized that coral reef exoskeletons were composed of calcium carbonate dissolved CO2 production, thanks to his research in the underwater world, field not covered by marine biologists.
How could a geologist use acid to get a pyrite fossil out of limestone?
Hydrochloric acid is used by geologists in the field to test if a rock contains carbonate minerals and to further distinguish between calcium and magnesium carbonate rocks. When acid is poured onto a non carbonate rock sample there will usually be no reaction. However calcium carbonate (limestone) will react by fizzing vigorously and magnesium carbonate (dolomite) will also react or fizz, but much more slowly. If the geologist suspects the sample in question is marble he will attempt to crush or powder part of the specimen using his geological hammer. When the acid is poured onto powdered marble, this will also react by fizzing. Some other sedimentary rocks, for example sandstones, may have mineral cements that are carbonates. As such acid can also be used as an aid in the identification of the cementing material. The "fizzing" is caused by the reaction of the acid with the carbonate rocks to produce carbon dioxide gas. The reaction takes the following form: HCl(aq) + CaCO3(s) = CaCl2(aq) + CO2(g) + H2O(l) Where: HCl = hydrochloric acid CaCO3 = calcium carbonate CaCl2 = calcium chloride CO2 = carbon dioxide H2O = water If the sample still does not react with acid in any way after following the above steps, the geologist will most likely conclude that the sample is not a carbonate of any form. However they may also take the sample back to the laboratory for further study. Please see the related links.

Do you have facts about farmers field?
They can be really big and they are owned by men called farmers and most of the time they use them to grow crops pretty much. I have seen some deer in a farmers field before. it russles the farmers jimmys.

Is farmer a collective noun?
There is no specific collective noun for farmers, in which case a noun suitable for the situation can be used, for example a cooperative of farmers, a family of farmers, a field of farmers, etc.

How might a geologist use acid in the field to identify carbonate rocks such as anhydrite and gypsum?
If you put cold dilute Hydrochloric acid on a carbonate rock the acid dissolves the rock and you get bubbles of carbon dioxide in the acid. This reaction will only happen with carbonate rocks.
