    Sand Quartz Feldspar Water and Grains JRank Articles

    Sand formed by weathering is termed epiclastic. Where fragmentation is rapid, granite crumbles before its feldspar has fully decayed and the resulting sand contains more feldspar. If fragmentation is slow, the resulting sand contains less feldspar. Fragmentation of rock is enhanced by exposure to fast-running water, so steep mountains are often source areas for feldspar-rich sands and gentler terrains are often source areas for feldspar-poor sands.

    Clays, rust, and sand that go into making soil beneath them, and ions that wash away. During chemical weathering, sodium is released as dissolved ions and transported to the ocean, where Most of it stays in the water for a while, making the water salty.
