Scarp
An open pit mine, or quarry, is exposed on the surface.
When the exposed surface of water is larger the evaporation is faster.
It is the amount of surface of a solute that is exposed to the solvent. The smaller the pieces of the solute are, the larger the surface area that is exposed to the solvent.
ALL reactions (apart from Nuclear) take place on the surface. By crushing the solid you are increasing the surface area and also the SA/Volume ratio. This increased surface area increases the area available for the dissolution reaction.

The larger the exposed surface area - the faster evaporation occurs.

Sulfide rock create when exposed to rain and air on the surface sulfuric acid.
Sedimentary rocks, when exposed on the surface, is exposed to weathering.
"Hot liquid rock" exposed at or above the surface is called lava whereas if it is below the surface it is called magma.
retina
It is the area of the exposed surface. So if you take a cube, the surface area is the sum of the areas of each of the 6 faces. They are all the same in the case of a cube. In general, add up the surface area of each exposed surface and this is the total surface area.
unconformity
Ores near the surface will be quarried or opencast mined.
