Crest is the top line of a hill, mountain, or wave whereas trough is a narrow depression (as in the earth or between ocean waves or in the ocean bed).
Crest is the highest or extreme point of something (usually a mountain or hill) whereas trough is a channel along the eaves or on the roof; collects and carries away rainwater.
