Gravel occurs naturally on Earth as a result of sedimentary and erosive geological processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments
Rock mechanics is a theoretical and applied science of the mechanical behavior of rocks and rock masses. [1] Compared to geology, it is the branch of mechanics concerned with the response of rock and rock masses to the force fields of their physical environment.

Parking lots are highly impervious.. Impervious surfaces are mainly artificial structures—such as pavements (roads, sidewalks, driveways and parking lots, as well as industrial areas such as airports, ports and logistics and distribution centres, all of which use considerable paved areas) that are covered by water-resistant materials such as asphalt, concrete, brick, stone—and rooftops.
