The rock and minerals process

  • What is the difference between a rock and a mineral?

    A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.

    Chemical weathering can only act on the surface of a rock or mineral or where a crack allows air and water into the mineral/rock. Therefore, more chemical weathering happens if and where the rocks have first been mechanically weathered. Mechanical weathering physically breaks a rock into smaller pieces of the same rock or minerals in that rock.
