Minerals are classified into groups based on _______.
Characteristics?
4 answers
Origin maybe? For example compressed from sediments or spewed from volcanos or risen from deep in the crust ? What does your book say?
Some of the answer choices are ionic, covalent, rock, mineral, melt, crystallize, characteristics, or color. I was thinking either characteristics or color, but color isn't really used to identify minerals, so I was leaning toward characteristics.
One of my daughters classified minerals by "prettyness". The question is very vague.
Maybe but I'm going to go with characteristics. It seems to be the most reasonable of my answer choices.
