What are the major effects of the physical separation of group members? how can distance, in some cases, be beneficial to groups and teams?

One of the major effects of physical separation would be it can be difficult to be able to have a bond with the members since they have less connection. Another is understanding members can be difficult as body language and facial expressions cannot be seen. However, distance can also be beneficial as members can work independently and can then gain trust from each other as they are from different places or timezones.
