Which is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure? A. fossil B. metal C. mineral D. rock

C. mineral

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;

1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

Mineral is the classification of any naturally occurring solid inorganic 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.

Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
