Morton said the breeze blowing to the Doug Wade Stand end was pivotal in helping Geelong gain a 44-point lead at the first break.
"I think the wind was very influential, especially early on in the game," he told melbournefc.com.au.
"They were kicking with the wind and we were trying to kick against it and our skill was terrible. By quarter-time we'd made a lot of clangers and we turned the ball over a lot.
"At the end of the day, when the winning margin is what the margin was at quarter-time, you look back and think about what was different in the first quarter and it was the wind."
Melbourne kicked the first three goals in the second quarter, resulting in a 10-zip start with majors booted to the Wade Stand end. During the second term, Morton said the wind had "died down".
"The unfortunate part was that we let them score in the second quarter and then for the rest of the game, it was pretty much goal for goal," he said.
"To be able to match it with Geelong in the second half was a credit to the boys. Letting them get away early in the match was our downfall today."
Still, Morton said the Demons were pleased to be able to match it with one of the best after quarter-time.
"We're all disappointed when we lose, but as a young developing club, you can only take the positives out of the game and the positives were that we almost matched it with the benchmark in the competition," he said.
"We probably let ourselves down with our skill level in the first quarter and they capitalised on our mistakes, but at the end of the day, going into the game review that'll be one of the big outcomes."
Morton, who finished with three goals and 18 touches after starting on the bench, said the reason he was beginning the game on the pine in the past few weeks was form-related.
"I haven't been playing my best footy and the coaches just want me to make an impact when I come on and last week the coaches wanted me to get my work-rate up," he said.
"I had 18 one-percenters last week and that's the highest I've ever got, so I was rapt with that and that gave me the confidence coming into this week."
"In the last quarter, I was isolated down in the goalsquare, which was a lot of fun. It reminded me of my youth, when I was playing club footy and luckily I got a couple of goals and it made it a good day, although they won and that's the disappointing thing."
