RESPONSE:

Let's take a closer look through discussion and example, which you can draw on of your final copy.

1. Describe the movement of sand within a beach environment. Include those factors, both natural and human-induced, that affect sand movement.

A beach is a geological formation consisting of loose rock particles such as sand, gravel, shingle, pebbles, cobble, or even shell along the shoreline of a body of water. Thus, beach environments are deposition landforms, and are the result of wave action by which waves or currents move sand or other loose sediments of which the beach is made as these particles are held in suspension. Alternatively, sand may be moved by saltation (a bouncing movement of large particles). Beach materials come from erosion of rocks offshore, as well as from headland erosion producing deposits of scree, which later erodes to sand (comprising particles or granules ranging in size from 0.0625 (or 1⁄16) to 2 millimeters). A coral reef offshore is a significant source of sand particles that is moved onto the beach in the above movements. http://en.wikipedia.org/wiki/Beach#How_beaches_are_formed

Coastal lands and sediments are constantly in motion. Breaking waves move sand along the coast, eroding sand in one area and depositing it on an adjacent beach. Tidal cycles bring sand onto the beach and carry it back ...
