multiple - choice question why is slate monominerallic? it contains many minerals it contains only one…

Brief Explanations:

The term "monominerallic" means a rock is composed of only one mineral. Slate is mainly composed of clay - minerals that recrystallize during metamorphism, often dominated by mica - like minerals but not just mica. However, it is considered monominerallic because it is dominated by one type of mineral - like material. The option "It contains many minerals" is incorrect as monominerallic implies the opposite. The option "It contains only one mineral called mica" is an over - simplification as it's not just mica and there can be other minor components, but the key is the dominance of one mineral - like group.

Answer:

Neither of the provided options is entirely correct, but if we must choose based on the concept of monominerallicity, the idea that it is dominated by one type of mineral (even if not just mica) is the key. If we assume the closest meaning to the correct concept among the options, the second option "It contains only one mineral called mica" is closer in the sense of emphasizing a single - mineral composition (though inaccurate in naming only mica), while the first option "It contains many minerals" is wrong for a monominerallic rock.
