Te mechanizmy of Coastal Erosion

Erosion is the removal and transport of rock and sediment by thee action of waves, currents, tides, wind, and weathering. Along coastride lines, wave energy is thee dominant erosive agent, but thee specific mechanisms vary witch rock type, wave climate, and tidal range. Understanding these processes is fundamentamental to prediting how a coast will respond to ching condititions.

Erosional Coastal Landforms

Te type and rate of erosion determinate thee specific landforms that develop. Hard, resistant rocks (np., granite, basalt, quartesite) tend to produce steep, rugged cliffs, while softer rocks (np., clay, shale, faul) erode more rapidly to form gentle slopes or bays.

This happens wherever there a reduction in energy - behind headlands, in sheltered bays, at river mouths, or where water depth progress elare highly dynamic. Depositionional landforms are generally compose of sand, build, or shingle (pebbles / cobbles) and are highly dynamic, shifting shape with every storm tide.

Today, global mean sea level is rising at an akcelerating rate due to climaty change, but local and regional variations are influenced by tectonic movements, glacial isostatic addistment, and oceain dynamics.
