which statement is an example of an observation a scientist would make to classify a rock? a rock is larger…

Brief Explanations:

An observation for classifying a rock should be about its physical - related characteristics. Location of discovery can be an important factor in rock classification. The first option is a relative size comparison not specific to classification. The third option is about formation process which is more of an inference. The fourth option is about a post - event change. Finding a rock in a stream gives information about its possible transport and depositional environment which helps in classification.

Answer:

A rock was found in a stream.
