Before we discuss the other types of rocks (Sedimentary and Metamorphic) we need to have an understanding of the processes that cause the breakdown of rocks, either to form new minerals that are stable on the surface of the Earth, or to break the rocks down into smaller particles . This process is called weathering,

The environment is another factor that affects the weathering process, such as the given temperature of an area, and the amount of rainfall that the area receives. The concentration of the amount of material is also an important factor that influences weathering;

"In the engineered weathering process we have found a way to swap the weak carbonic acid with a much stronger one (hydrochloric acid) and thus accelerate the pace to industrial rates," Kurt Zenz House says.

Unlike the rocks of Earth, where there are many things which cause erosion, there are only two main weathering agents on Mars: wind and acid fog. Acid fog is very important, but because there is not a lot of water, the action of sand and wind is the most important thing to cause changes to the planet's surface.

Because of its wood content, natural color shifts do occur in Trex products. ... The weathering process may be accelerated in dry areas by periodically wetting down the deck using a garden hose. Areas in heavy shade, or vertical components such as posts and balusters, may take considerably longer to fade.
