GEOG 2051 : Final Exam Review Geog 2051
Document Summary
Primary coasts: coasts that have been formed from terrestrial (land). Fiords: glacial erosion produces long, narrow, deep bays. Secondary coasts: marine processes cut or altered the coastline. A wave cut notch turns into a wave cut platform. Beach cycle: waves enter shallow water which carries sediment onto the beach. The backwash is slower, until the up rush is steeper, which creates equilibrium. The waves bring sediment up onto the beach. Storm-fairweather profile changes: fair weather/swell conditions occur only in the spring and summer. They have long waves, which have longer periods inbetween, lower wave heights, they push sediment onshore, have wider beaches, and shorter, and steeper foreshore. They have relatively short, but rather high waves, the net offshore transport is greater, the beach is narrower, the foreshore is longer, and flatter, and more energy is produced and used. Spits: extensions of the general trends of the shoreline such as sandy hook!
