Playing his 250th game, Taylor Walker booted 10 goals in a game in the Eagles 27.12 (174) to 8.4 (52) defeat.
Walker's feats helped Adelaide (seven wins, six losses) climb into the top eight and boost their percentage by 11.3.
West Coast remains at the bottom of the ladder with one victory from 12 matches heading into the mid-season bye.
There were few positives for the Eagles, aside from the continued strong form from emerging ruck Bailey Williams and mid-season rookie draftee Ryan Maric's impressive debut.
Williams worked into the game strongly after the Crows started fast, and finished with 20 disposals, a clever snapped goal, six clearances and 35 hit-outs.
The Crows win by more than 100 points!
