Posing usually indicates more concentration and time than can be achieved "in the air"; nevertheless, posing [somehow] in the general vicinity of a sandy beach can be loosely characterized as 'pose in the sand', since sandy beaches involve plenty of sand, in which people may pose.


Consider the statement "A group of young people posing in the air on a sandy beach.". Based on this "A group of people pose in the sand." a true statement? Yes, no, or I don't know?
