Weathering Wikipedia

Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.Weathering occurs in situ (on site), that is, in the same place, with little or no movement, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice

Understanding How Granite Slabs Are Made

After granite has first been mined out of the earth, it will be in a very rough form. After the mining process is complete, the granite will be sent to a workshop to be transformed into slabs. A technician will use milling machines to cut and polish the granite. Once milling has been completed, the slab will be between 7 and 9 feet long.
