Topic: Minerals and their Properties 1) How does streak differ from color? 2) How does cleavage differ from a fracture? 3) Give one mineral and their property thet makes it unique; e.g. magnetite is magnetic.
Streak is the color of a mineral's powder. Streak is a more reliable property than color because streak does not vary. Minerals that are the same color may have a different colored streak.
Cleavage is the property of a mineral that allows it to break smoothly along specific internal planes (called cleavage planes) when the mineral is struck sharply with a hammer. Fracture is the property of a mineral breaking in a more or less random pattern with no smooth planar surfaces.
Magnetite is best known for its property of being strongly attracted to magnets. ... Commonly known as Lodestone, this magnetic form of Magnetite is the only mineral that is a natural magnet. Due to the magnetism of Lodestone, small iron particles are often found clinging to its surfaces.
