Answer:
The amount of water on the Earth is constant, or nearly so. Actually, the amount is increasing ever so slightly due to volcanic eruptions expelling water vapor into the atmosphere, but, for all practical purposes, the amount of water (as a gas, liquid and as snow and ice) can be considered to be constant.
Explanation:
Use the D = M/V equation, in which Density can be found by dividing <em>Mass/Volume</em>.
To solve, first find a rectangular prism tub that is filled to a certain level. Next, place the rock inside to find the amount of displacement (or how high the water level goes up.) In this way, you can find the <em>volume of the rock</em>.
Next, solve for the Mass. This can be found by dividing the total weight from the gravitational pull. This would give you the mass.
Finally, to find Density, divide the Mass found with the Volume. This would give you your final answer

Answer:
Minerals
Explanation:
Minerals are usually defined as naturally occurring inorganic substances, that are comprised of specific chemical composition as well as having a well organized internal structure of atoms.
Different mineral forms under different conditions and under different geological settings. These minerals combine with one another giving rise to the formation of rocks.
They are characterized by the presence of both physical as well as chemical properties.
Example of some minerals includes, Calcite, Fluorite, Quartz, and Feldspar.
