The term weathering is used in the Earth Sciences to denote the in situ breakdown and alteration of rocks and
minerals. In the near surface environment, pressure, temperature and water availability differ significantly from
those prevailing at the crust’s interior. Because of this disequilibrium, exposed rocks are easily attacked,
decomposed and eroded by various chemical and physical surface processes. The term weathering conveys, as
well, a close linkage with atmospheric conditions (i.e., weather). At any rate, weathering involves a set of
processes that prepare rock material for transport, and such movable debris or regolith is defined as “the mantle of
in situ and transported material that covers the landscapes across the world” (Scott and Pain, 2009).
