what are the five characteristics of a rock?

Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

['Color : Bright Yellow.', 'Luster : It has a shine or glow.', 'Ductility : It can be beaten into extremely thin sheets of gold leaf.', 'Malleability : Capable of being shaped or bent.', 'Conductivity : Good electrical conductor.', 'Solubility : Solubility (ability to be dissolved)']

Part of Hall of Planet Earth. There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.

These include: color, streak, hardness, luster, diaphaneity, specific gravity, cleavage, fracture, magnetism, solubility, and many more. These physical properties are useful for identifying minerals. However, they are much more important in determining the potential industrial uses of the mineral.

Types of Rocks There are three basic types of rock: igneous, sedimentary, and metamorphic. Extremely common in the Earth's crust, igneous rocks are volcanic and form from molten material.

Electromagnetic Properties of Rocks and Minerals The physical properties of rocks, which affect the propagation of the electromagnetic field, are electrical conductivity, dielectric permittivity, and magnetic permeability.
