The boulder is covered with a continuous layer of moss. Suggest hypotheses about the possible effect of moss cover on the rate of stone destruction.
The rate of destruction of a boulder covered with a layer of moss will be small, because moss retains moisture and prevents the sun from destroying the stone – in the sun the stone heats up, and moisture (temperature difference) destroys it. In winter, water stays in cracks and freezes; when it freezes, water expands and breaks the stone. Moss protects the stone from rapid destruction.
