Is a topographic map or a geologic map most useful for drilling a water well

A geologic map would be most appropriate because it can represent various layers of Earth’s surface from a side view or cross section. Such a map would be helpful in drilling a water well because it would show the different layers of rock and their depths, and would reveal where groundwater was and how deep they would need to drill to reach it.

Explanation:

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
