Question 1

Mineral

Answer 1

A mineral is a naturally occurring substance that is solid and inorganic representable by a chemical formula, usually abiogenic, and has an ordered atomic structure. It is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition.

Question 2

Rock

Answer 2

the solid mineral material forming part of the surface of the earth and other similar planets, exposed on the surface or underlying the soil or oceans.

Question 3

Element

Answer 3

a part or aspect of something abstract, especially one that is essential or characteristic.

Question 4

Compound

Answer 4

a thing that is composed of two or more separate elements; a mixture.

Question 5

Crystal

Answer 5

Question 13

Ore

Answer 13

a naturally occurring solid material from which a metal or valuable mineral can be profitably extracted.

Question 14

Metallic minerals

Answer 14

Minerals are naturally occurring substances that are solid and amorphous. They are described by different physical properties such as crystal structure, luster, hardness, color, fracture and more. Metallic minerals are minerals that contain metallic elements.

Question 15

non-metallic minerals

Answer 15

These are also called industrial materials and are typically some form of sediment. Non-metallic minerals are not malleable.

Question 16
