landform. These factors all contribute to create distinctive landforms. This essay will be identifying the ways in which these coastal landforms have been made Headlands and bays such as Beachy head on the south coast of England. Headlands and bays are often found on the same coastline. A bay is surrounded by land on three sides‚ whereas a headland is surrounded by water on three sides. This because the formations are caused by bands of resistant and weak rock which when in contact with the discordant

constructed to protect the headland from further wave erosion and to ensure the pedestrian pathway stayed open for access to the headland. The wall is ____________metres long and was built in _________. * Processes affected: The main processes affected are wave refraction‚ wave erosion and coastal transportation. The waves refract around the headland and attack the sides of the headland. Because of the sea wall the waves can no longer attack the side of the Otakimiro Headland. This means the waves

Coastal Erosion‚ Coastal Transportation and Coastal Deposition. The elements that interact to produce natural processes are wind‚ waves and tides. Each phenomenon at Muriwai’s coastal geographic environment has been produced by interaction. Coastal Erosion is a process at Muriwai that gradually wears away the rock particles of the earth’s surface‚ transporting them to another location. There are many types of processes that cause erosion at Muriwai such as wave erosion‚ wind erosion

geomorphology has been influenced by tectonic processes (rocks)‚ alluvial processes (water) and climatic processes (weather). Hydrological Processes Hydrological Processes refer to water. Waves are continually affecting Otakimiro Point (i.e. the Headland). At Muriwai‚ waves are responsible for shaping the coast everyday (and night!). Hydrological Vocab * The movement of waves back down the beach. * The movement of waves up on to the beach. * These occur on shores with a steeply angled

waves approach an irregular coastline Hydraulic Action - An erosion process - where air becomes trapped and compressed in a joint / crack in a rock by a breaking wave‚ gradually breaking rock apart. Abrasion - An erosion process where cliffs are worn away by rocks and boulders thrown against them by the waves Solution - An erosion process where acids in the sea water gradually dissolve minerals in rocks. Wave Pounding - An erosion process where the shear force of the waves constantly hitting

coast where the geological sequence has produced distinctive coastal landforms. At Old Harry/Ballard Point and at Durlston Head are outcrops of rocks resistant to erosion. The chalk escarpment which bends from St Oswald’s Bay eastwards to Old Harry increases in width to produce steep 60 metre cliffs. Erosion at the chalk headland of Ballard Point has produced stacks‚ wave cut platforms‚ notches‚ caves and arches. The more resistant Portland limestone has also produced vertical

than others‚ making waves stronger and more powerful. I think wind is the most important factor. 3. I think the steepest beach will be Hurlstone because it’s the end of the beach where pebbles will be at their smallest and roundest due to erosion. 4. I think the gentlest beach will be gore point because it’s at the beginning of the beach where the pebbles will be at their largest and more angular.
