The largest and most common caves are those formed by chemical reaction between circulating groundwater and bedrock composed of limestone or dolomite. Depending on climate, topography, and amount of snowfall over time, tidewater glaciers may periodically experience rapid retreat, creating many large icebergs. Softer rocks wear away more quickly than harder rocks. Where headlands and bays form the coastline is discordant. Eventually sea caves may form in less resistant, easily erodible bedrock located on promontories. Kenai Fjords National Park in Alaska is a perfect example of rocky coasts. This leaves a section of land jutting out into the sea called a headland. Waves approach the shore at some angle so the inshore part of the wave reaches shallow water sooner than the part that is further out. There is a range of landforms of erosion found along the coast. There are four types of erosion by waves: Abrasion - waves carry material which thrashes against the cliff and progressively disintegrate it. Headlands are formed when the sea attacks a section of coast with alternating bands of hard and soft rock. During these weathering events, the sediment is washed away by the rain or wave action.

Thus, the wind has a direct and indirect effect on the formation of coastal landforms. Another type of weak zone is formed where dissimilar types of rocks are inter-bedded and one is weaker than the other. There is also erosion by wind, weathering, sub-aerial processes, and mass movement. Wind acts both as an element that erodes the rocks and a force that determines the direction of the waves. Coastal landforms can be formed either by erosion or by deposition. Why does Keith Lemon wear bandages on his hands. Rocky coastlines have many spectacular features. Sea caves are formed by the power of the ocean attacking zones of weakness in coastal sea cliffs. According to NationalGeographic.com, bays are formed through various ways, such as plate tectonics, overflowing of the ocean to a coastline and the slicing of a glacier through a bedrock.

Will you still be able to buy Godiva chocolate? Sandy beaches are usually found in shallow bays with fewer waves and shallow water. There are four types of erosion by waves: The longshore currents are created when waves are refracted while entering into shallow water. The detached rock can also get accumulated at the base of the cliff as debris. Plate tectonics, which involves continents drifting together and rifting apart, is responsible for the formation of numerous large bays. Rias are formed by rivers and have more gradual slopes. Discordant coastlines form where geology alternates between bands of hard and soft rock (see image below). As the waves erode the coastline, the soft rock will be eroded quicker. strips that are resisent rock (hard rock) in between each other, Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. If icebergs drift into nearby shipping lanesespecially those containing oil tankers, for example, in Alaskasuch recession can be catastrophic. Waves cut arches and sea stacks that jut into the water. The areas of softer rock retreat, forming bays, while hard rock is eroded slower, resulting in headlands. Bays are usually formed where weaker rocks like clay and sand .
