Gravity
The mass movements are: slump, creep, falls, slides, flows and avalanche.

gravity.
Yes, thermals do occur as a result of hot and cold air movements.
You didn't include the Movements in Question
Landslides, mudflows, slump and creep
if the steepness of a slope exceeds the stable angle, mass movements become more likely.

At plate boundaries.
People living on a day to day basis are a group unlikely to be recruited into mass movements for major changes in society. The goals of such people are to merely survive and any distractions such as mass movements, are a low priority.
