What property causes the mineral galena to break into tiny cubes?
The property of cleavage.
What mineral has cubic cleavage?
An example of rhombic cleavage would be siderite and rhodochrosite. Remember that this is basically a "partically squashed box." Essentially, the direction of deformation in a rhombohedron occurs in one of the three diagonals that run from one corner of the cube to the other. Calcite is not a particularly fabulous example of a rhombohedron, because it is considered to be cubed.
Which mineral had 4 directions of cleavage?
I think Calcite. Calcite is 3 on the hardness scale and sometimes you can break it into cubes. The difference between Calcite and Quartz is that Calcite is a milky white.
The source of lead?
The main source of lead is an ore called galena. Galena is a crystalline form of lead sulphide (PbS), is grey and forms cubic crystals (or sometimes shaped like cubes with their corners sliced off) and occurs abundantly in many countries. Near where I live in the UK (in the Mendip Hills) are remains of lead mines that were worked 2000 years ago by the Romans. If you look carefully you can still see small amounts of galena on the surface of the ground even today.
What is a mineral that has a colorless chunk that breaks apart into cubes it has no luster and is soft enough to be scratched by fluorite?
Halite, a colorless chunk that breaks apart into cubes and has no luster and is soft enough to be scratched fluorite, and when it gets wet it starts to dissolve. Did that help you?
What property causes the mineral galena to break into tiny cubes?
The property of cleavage.
What mineral breaks easily into cubes?
Galena, i thinx
What mineral has a nonmetallic luster and can have the shape of little cubes?
galena, pyrite, fluorite, perovskite, or halite cubes
What mineral is metallic silver very dense and an ore of lead?
Galena is an interesting ore of lead (lead sulfide). It can form in isometric crystals and has perfect 4 direct cleavage forming cubes.
Is ice cubes an mineral?
no
Why are ice cubes not a mineral?
Ice cubes are not naturally-occurring in the cube form, they are man-made. But ice itself is a mineral.

Which of the mineral has non-metalic luster and can have the shape of the little cubes?
Halite.
When is water a mineral?
Water as a solid, in the form of ice, is considered a mineral when it is naturally occurring. Ice in snow banks is considered a mineral but ice cubes you make in your freezer are not a mineral.
What does galena look like?
Galena crystals are cubic or octahedral and are in the isometric (cubic) crystal system.
