      • swash
        • the rush of seawater up the beach after the breaking of a wave
    • longshore drift
      • the movement of material along a coast by waves which approach at an angle to the shore but recede directly away from it.
    • erostion
      • the process of eroding or being eroded by wind, water, or other natural agents.
    • Once the small pieces of rocks are changed or broken apart by weathering, they may start to be moved by wind, water, or ice. When the smaller rock pieces (now pebbles, sand or soil) are moved by these natural forces, it is called erosion
    • Formation of metamorphic rocks. Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form.
    • Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.
