Costal Features Along Maracas Bay

Tides often determine the range over which depository is deposited or eroded. Areas with high tidal ranges allow waves to reach farther up the rim, and areas with reduce tidal ranges produce deprossosition at a smaller elevation interval. The tidal range is influenced by the size and shape of the brinkline. Tides do not typically cause erosion by themselves however, tidal bores can erode as the waves surge up river estuaries from the naval. 3 Waves erode coastline as they break on shore releasing their aptitude the larger the wave the more(prenominal) energy it releases and the more sediment it moves.Coastlines with longer shores have more room for the waves to disperse their energy, turn coasts with cliffs and short shore faces give little room for the wave energy to be dispersed. In these areas the wave energy breaking against the cliffs is higher, and air and piss are compressed into cracks in the rock, forcing the rock apart, breaking it down. Sediment deposited by waves comes from eroded cliff faces and is moved along the coastline by the waves. This forms an abrasion or cliffed coast. Sediment deposited by rivers is the dominant influence on the amount of sediment located on a coastline. 4 Today riverine deposition at the coast is often blocked by dams and other human regulatory devices, which eliminate the sediment from the stream by causing it to be deposited inland. Like the ocean which shapes them, coasts are a dynamic environment with constant change. The Earths natural processes, curiously sea level rises, waves and various weather phenomena, have resulted in the erosion, accretion and reshaping of coasts as well as flooding and creation of continental shelves and drowned river valleys
