How many choices does a dichotomous key provide?

A dichotomous key is an outline of a classification system that seeks to identify common organisms (usually trees, flowers, birds or other groups of similar organisms) by systematically evaluating individual characteristics. The name is derived from what it does - provides the instructions (key) for separating organisms into two ("di") groups and then subdividing those groups into two until only one organism is left in the group.

Why not have trichotomous instead of dichotomous?

Many things in life can be analysed in terms of two alternatives. Either we will see this movie or we won't. You could analyse it in terms of three alternatives if you wish. We might see the movie in a movie theater, we might not see the movie in a movie theater, or we might wait for it to come to television. Even then, those are not the only alternatives. We might also buy the movie on DVD. We might read the novel upon which the movie was based. We might want to film our own version, in a different language. And so forth. The number of choices you want to make is up to you. Nonetheless, it is frequently convenient to narrow things down to two choices, in which case you have a dichotomy. If you prefer a trichotomy, that is your privilege.


How can a dichotomous key be used to identify rocks?

A dichotomous key is a tool used to identify many things in the Sciences ranging from rock types to leaf/tree species to living organisms such as bacteria. You can google many such keys. It is simply a numbered list of questions, each with a "yes" or "no" answer for each one. Your answer will direct you to the next question in the key until you arrive at the identity of the rock, leaf/tree or bacteria. Many rock identification keys will ask you questions about colour, crystal size, hardness( can it scratch glass or can it be scratched by a nail ), magnetism and its reaction to acid( usually vinegar ). Good luck!
