Answer 1

What are the five properties that make mineral a mineral?

A mineral is a natural substance, of defined chemical composition, normally solid and inorganic, and that has a certain crystalline structure.

•All minerals are solid.

•The minerals have formed naturally.

•All minerals have a unique and specific chemical composition.
All minerals have a crystalline structure.

•All minerals are organic compounds

How do the rocks and minerals differ?

A mineral is different from a rock because rocks can be an aggregate of minerals or non-minerals and does not have a specific chemical composition.

How igneous rocks form?

Igneous rocks are formed by the cooling and solidification of molten rock matter, magma. Depending on the conditions under which magma cools, the resulting rocks may have coarse or fine granules.

How do the extrusive and intrusive rocks form, one example of each kind.

Plutonic or intrusive rocks were formed from a slow and deep cooling of magma. The rocks cooled very slowly, thus allowing the growth of large crystals of pure minerals. Examples: granite and syenite.

Volcanic or extrusive rocks are formed by rapid and surface cooling (or near it) of magma. They were formed by ascending molten magma from the depths filling cracks near the surface or by magma emerging through volcanoes. Subsequent fast cooling and solidification, resulting in the formation of fine-grained minerals or glass-like rocks. Examples: basalt and rhyolite.
