Question
Which statement describes the difference between crystal form and cleavage?
Question 4 options:
The crystal form is the tendency of some minerals to break along a flat, parrallel surface and the cleavage is color of a substance after it has been ground or scratched to make fine powder.
Crytal form is a description of how light reflects from the surface of a mineral where as the cleavage is a measure of the resistance to scratching.
Crystal form and cleavage are the same thing.
Crystal form describes the different geometric shapes in which a minerals crystal will grow to be, where as the cleavage refers to a weak plane of surface within a mineral in which the mineral will break.
Question 5
Plagioclase Feldspar tends to have striations (stripes across a cleavage surface) and Potassium Feldspar does not.

Explanation / Answer
1) Crystal form describes the different geometric shapes in which a minerals crystal will grow to be, where as the cleavage refers to a weak plane of surface within a mineral in which the mineral will break.
Crystal form is the group of faces which have like positions with respect to crystallographic axes. and cleavage is the plane of weakness along which the minerals will break easily
2) True. plagioclase minerals are charecterized by the presence of parllel lines called striations
