Sedimentary rock and the processes that create it, which include weathering, erosion, and lithification, are an integral part of understanding Earth Science. This is because the majority of the Earth’s surface is made up of sedimentary rocks and their common predecessor, sediments. Even though sedimentary rocks can form in drastically different ways, their origin and creation have one thing in common, water.

Matter is made of atoms. Atoms consist of subatomic particles—protons, neutrons, and electrons.

it is essential to examine the fundamental unit of all matter, the atom.

Because of these discrepancies, the International Mineralogical Association in 1985 amended the definition to: “A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes.”

Calcite is quite often formed by organic processes but is considered a mineral because it is widely found and geologically important.

water and mercury are liquid at room temperature. Both are considered minerals because they were classified before the room-temperature rule was accepted as part of the definition

the classic definition of a mineral is: Naturally occurring Inorganic Solid at room temperature Regular crystal structure Defined chemical composition

metamorphic (rocks produced by alteration of other rocks by heat and pressure.

sedimentary (rocks made of products of mechanical weathering (sand, gravel, etc.)

igneous (rocks crystallizing from molten material)

A rock is a substance that contains one or more minerals or mineraloids.
