A crystal structure is the repetitive patterns in a mineral form. Cleavage is the ability of a mineral to break into flat surfaces. A fracture is a term used for an irregular way a mineral breaks apart.
Study of the mineral and the crystal structure.
- The underlying internal architecture of a crystalline substance, or its crystal structure, is expressed in a mineral's outward morphology. The three-dimensional regular (or ordered) arrangement of chemical units (atoms, ions, and anionic groups in inorganic materials; molecules in organic substances) that make up a crystal structure is reproduced in different ways via translational and symmetry operations and are referred to as motifs.
- The term "cleavage" describes the way some minerals fracture along specific structural lines of weakness. Mica is a wonderful example since it breaks along flat planes that are very closely spaced apart and produces thin "sheets."
- A mineral can fracture when it splits in an irregular pattern without any smooth, plane surfaces.

Answer:
nationalism is pretty much going with the flow or majority. identification with one's own nation and support for its interests, especially to the exclusion or detriment of the interests of other nations.
and then sectionalism is like when you are just in favor of one half of your country instead of all of it. restriction of interest to a narrow sphere; undue concern with local interests or petty distinctions at the expense of general well-being.
An example would be:
if half of the country wants free ice cream for dinner, and half of the country wants free brownies for lunch, a nationalist would pick what most of the nation wanted, but a sectionalist would pick what his side of the nation wanted. Hope this helps you and pls mark me brainliest.
