1. define the following.\n1. rocks\nare a solid aggregates composed of one or more minerals or mineraloids\n2. minerals\n3. list the properties used to identify minerals.

Answer

Brief Explanations:

  1. Rocks are defined as solid aggregates of one - or more minerals/mineraloids. Minerals are naturally - occurring, inorganic, solid substances with a definite chemical composition and a characteristic crystal structure. Properties used to identify minerals include color, luster, hardness, cleavage, fracture, specific gravity, and streak.
  2. Minerals are naturally - occurring, inorganic, homogeneous solids with a definite chemical composition and an ordered atomic arrangement.
  3. Color: The visible color of the mineral. Luster: The way a mineral reflects light (e.g., metallic, non - metallic). Hardness: Resistance to scratching, measured by Mohs scale. Cleavage: Tendency to break along smooth, flat planes. Fracture: The way a mineral breaks when it does not break along cleavage planes. Specific gravity: Ratio of the weight of a mineral to the weight of an equal volume of water. Streak: The color of the powder of a mineral when it is scratched across an unglazed porcelain plate.
