Are coastal zones narrow and dynamic

Geography Studies, Coastal Zones

Coastal zones may be described as narrow and dynamic. Coasts are the dynamic relationship of water, air, and land. Wind and waves, tides and currents, migrating sand dunes and mangrove swamps, and a variety of plant and animal life, all combine to form our ever-changing coasts. The dynamic nature of our ever-changing coasts is what gives it their great diversity. Narrow coastal zones tend to be more subject to natural erosion, which makes it easily visible. Narrow coastal zones have little sand on their beaches to be carried away and deposited so the seasonal changes that occur in summer and winter are very noticeable.

Coastal lands and sediments are always in motion, constant breaking waves move sand along the coast, eroding sand in one area and depositing it on another beach up or down from the eroded area. Tidal cycles bring sand onto the beach and carry it back into the surf, during the seasons of summer and winter constructive (summer) and d...
