Rocks vs Minerals

Study Notes

Definition of Rocks

Rocks are naturally occurring solid aggregates of one or more minerals or mineraloids.
They are classified into three main types: igneous, sedimentary, and metamorphic.

Definition of Minerals

Minerals are naturally occurring inorganic solids with a definite chemical composition and a crystalline structure.
They are typically classified by their physical and chemical properties, such as hardness, color, and luster.

Formation of Igneous Rocks

Igneous rocks are formed through the cooling and solidification of molten magma or lava.
If cooling occurs beneath the Earth's surface, the rocks are termed intrusive or plutonic; if cooling happens on the surface, they are called extrusive or volcanic.

Characteristics of Igneous Rocks

Igneous rocks are characterized by their texture, which can range from coarse-grained to fine-grained, depending on the cooling rate.
Common minerals found in igneous rocks include quartz, feldspar, and mica.
Color can vary significantly, influencing the classification into light or dark igneous rocks based on mineral composition.

Composition of Minerals

Minerals are compounds, typically composed of two or more elements, bound together in specific ratios and structures.
Common elements found in minerals include silicon, oxygen, aluminum, iron, calcium, sodium, potassium, and magnesium.
