How do I turn this..(look below).. into a Proverb?

A detached fragment of the terrestrial lithosphere, whether of igneous, sedimentary, or metamorphic origin, and whether acquiring its approximation of sphericity through hydraulic action or other attrition, when continually maintained in motion about its temporary axis and with its velocity accelerated by an increase in the angle declivity, is, because of abrasive action produced by the incessant but irregular contact between its periphery and the contiguous terrain, effectively prevented from aculating on its external surface an appreciable amount of the crytogamous vegetation normally propagated in umbrageous situations under optimum conditions of undeviating atmospheric humidity, quiescence, and comparative sequestration from corrosive-erosive agencies.
