geologist, larry coates, hangs a mile above the river of the grand canyon and finds evidence of past ______.
forest creatures
humans
river creatures
sea creatures

Explanation:

The Grand Canyon's geological history includes periods when the area was covered by seas. Geologists studying its rock layers often find evidence of sea - dwelling organisms. Forest creatures are land - based and not typically associated with the Grand Canyon's geological past in this context. Humans are a relatively recent species and not what a geologist would find evidence of in the context of the Grand Canyon's ancient past. River creatures are from the current river, not the past geological record in the same way as sea creatures. So the most appropriate answer is sea creatures.

Answer:

D. sea creatures
