When drops of water evaporate on porous materials, they can leave behind minerals and impurities present in the water. As the water evaporates, these minerals are deposited on the surface, creating spots or stains. This is more prominent on porous materials because the minerals can penetrate deeper into the surface, making the spots harder to remove.

Water can penetrate the small pores in gritstone cliffs. When the temperature drops, the water freezes and expands, putting pressure on the rock and causing cracks to form.
