Answer:
Minerals.
Explanation:
Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
<em>Hence, inorganic, crystalline substances found naturally within earth are known as minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc. </em>
