Bay-mouth bars may extend partially or entirely across the mouth of a bay; bay-head bars occur at the heads of bays, a short distance from shore. In emergent coasts, wave energy, wind, and gravity erode the coastline. Communities thus affected attempt measures to keep their harbor open. D. Siberia, 66) A Fjord is Even though the percentage is low, the volume is large, so melting the glaciers away will raise sea level and flood the coastlines of the world. Tidal flats are mostly submerged during ebb tides. Along these lines, they most usually happen across counterfeit narrows and stream passages because of the deficiency of motor energy in the current after wave refraction. Tombolos are sometimes referred to as "tied islands", because it seems to tethered to the coast.
