  • What happens when granite is weathered?

    Weathered rock fragments are one of the constituents of soil. (See section on SOIL). What happens after this? o Quartz grains may be eroded, becoming sediment. The quartz in granite is sand- sized; it becomes quartz sand. The quartz sand will ultimately be transported to the sea (bed load), where it accumulates to form beaches.

  • 8.5 Weathering and Soil Formation Physical Geology

    The types of weathering that take place within a region have a major influence on soil composition and texture.

  • Sand - Wikipedia

    Sand is a granular material composed of finely divided rock and mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt . Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. Sand dunes in the Idehan Ubari , Libya. Depiction of

    Oct 26, 2000· Sedimentary rocks are classified on the basis of the texture (grain size) of the rock, and composition. The basic classification only concerned texture, using the Wentworth size scale.But any full rock name must specify both texture and composition. Thus, an arkose sandstone is a rock of sand sized particles, with a high percentage of those particles being feldspar.
