Yes, but each team has a chance of finishing the survey for the planet for all of the teams. If you have a good survey team, it will find more stuff normally than half a dozen mediocre teams, it just will take longer.
Each team has a chance of finishing the survey based on its team survey score. The higher the score the lower the chance it will be finished. If you have multiple teams working the same site then each team will be checked on each 5 day cycle. In addition the experience gets spread out so each team does not improve as much as a single team working the site.

While this is an 8 month old post, I just had to comment on it because THIS IS IMPORTANT INFO.
I have simply been assuming this whole time that the survey score merely determined how long it takes - ie, higher means shorter is better.. Never did I assume it actually is THAT important. This was a simple sentence in the wiki that just did not stand out enough in importance.
WOW. This changes everything.
I had a period where I had too many officers, so I decided to make them do some good by putting teams on all the planets in my colonies systems. I had 3 teams with scores of 120, 140, and 190. I put a bunch of NOBODIES on my future colony planets. If I had known better I would have shipped them out to the asteroids to do their work while I saved the colonial planets for my ubergeologists.
