Table sugar is not a mineral because?
lianna [129]

Answer:

<h3><em><u>It is not made by a geologic process</u></em></h3>

Explanation:

A geologic process is a process which occurs dynamically at earth's surface or land forms. For example, volcanic eruption, weathering, erosion etc.

Whereas minerals are the inorganic substances which are homogeneous and occur naturally with a definite shape.

Sugar comes from plants and therefore it an organic compound. Hence it is not a mineral.

A table sugar undergoes a number of refining processes. It is in crystal form and it is made of more than one element which doesn't relate sugar with minerals.

Thus, we can conclude that <u>table sugar is not a mineral because it is not made by a geologic process.</u>

<u></u>
