Non foliated rocks, such as marble, form from limestone, a common type of sedimentary rock. Foliated rocks form from metamorphic or igneous rocks. Non Foliated rocks are more brittle than foliated rocks making them more susceptible to breakage.
whatis the flat part of the seafloor called?
Water contains distilled water which gives it taste. In disstilled water, these minerals are missing causing it to taste flat.
It would be important because cleavage is a tendency of some minerals to break along smooth, flat surfaces.
It breaks along its foliation, which consists of microscopically flat grains of clay
cleavage
this breaking point is called cleavage.
This property is called cleavage.

A short answer is:GraphiteA longer answer is:There are many minerals that break along flat surfaces. Probably the one that you would be most familiar with is "graphite". Graphite is a mineral formed from carbon atoms and it is used to make up the lead in pencils.Because of the structure of graphite, it tends to break cleanly in parallel, "flat" surfaces. It is not as evident in a pencil, because the piece of graphite is so small, but if you had a very large piece of graphite and broke it, you would see it break into flat flakes or plates.
Minerals do have zones of weakness. They are known as cleavage planes. It is the tendency for minerals to break along flat, parallel surfaces. They come in a variety of categories, but it is ultimately where the mineral will break if struck. It cal be basal, prismatic,cubic, rhombohedral, octahedral, or dodecahedral.
Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars. Cleavage is the result of the minerals' crystal structure that has weaker chemical bonds aligned in planes.
Minerals can have a cleavage plane, multiple cleavage planes, or no cleavage plane. A cleavage plane is an area of weakness in the crystalline structure where the mineral is prone to splitting.
When minerals break along certain planes, it is known as cleavage. Typically, the pieces will be the same form and be bounded by smooth, flat surfaces. Cleavage is determined by the number of cleavage directions and the angle(s) between them.If the mineral breaks in an irregular, jagged or splintered edge, it is said to have a fracture.
