This leads to a lack of beach material and therefore protection for the soft, boulder clay cliffs. Porlock has its own visitor centre and is only seven miles away from Minehead which is a popular tourist attraction in the county of Somerset. Every time a wave breaks the material is shifted up the beach in the direction of the prevailing wind. For example if the clinometere read 0 degrees on the tallest persons forehead, that must be noted and pointed at the persons forehead for every facet which was measured. I could have improved my investigation into coastal processes at Porlock bay by using more precise measuring equipment. Due to the geology at Porlock bay the resistant rock, red marl, is eroded quicker than the non resistant rock which is quartzite.
The headland has faults and cracks due to coastal erosion occurring at all times. Somerset The Coastal features in the Swanage area Minehead: Essays Plag Checker Hire Writer. The backwash then brings the material back down. For example if the clinometere read 0 degrees on the tallest persons forehead, that must be noted and pointed at the persons forehead for every facet which was measured. Swash carries the material up the beach at an angle.
In my investigation, I could have improved the way i collected the data or how i could have further investigated coastal processes at Porlock Longhore. I predicted that the pebble size at Hurlstone point will be smaller than at Gore point. Waves are longsjore and have the most energy when the wind is strong and has been blowing for a long time. The material will be eroded from Gore point which will make the beach smaller and transported by longshore drift to Hurlstone which will make a bigger beach.
This happens when the waves are full with energy. Hydraulic action also breaks off angular rocks of the cliff which is gathered on to the beach.
Longshore Drift – A Level Geography
Abrasion — This is when breaking waves hit the rocks and pebbles against the cliffs, which eventually wears away the land. Spurn Point — a coastal spit formed by longshore drift. I predicted that the pebbles lohgshore become smoother and rounder at Hurlstone point than at Gore Point due to attrition.
Coastal erosion eventually will erode down landforms and cliffs. We could have used a ranging pole instead of clinometeres which could have given a more accurate result of the facet gradient. View the coasts menu. Notice how the swash moves up the beach at an oblique angle then the backwash retreats at a right angle to the coast.
For example if the clinometere read 0 degrees on the tallest persons forehead, that must be noted and pointed at the persons forehead for every facet which was measured.
Somerset The Coastal features in the Swanage area Minehead: The size and energy of the wave will depend on the speed and the amount of time the wave has been moving. The backwash then brings the material back down. Attrition and abrasion erosion makes the pebbles rounder and smaller as longshoee travels through its journey from west to east.
Essay Sample – Is porlock bay affected by longshore drift? – OzEssay
The longshorf bit of my investigation was to find out if the pebble shape becomes rounder as it goes from the West to East. The swash moves beach material along the beach and the backwash, under gravity, pulls the material back down the beach at right angles to the coastline. The prevailing wind causes the waves to break the beach at an angle. This is illustrated in the photograph below where a large rock groyne longshkre Mappleton stops the supply of new beach material.
Quartzite is an example of a hard rock. As part of our geography coursework project we had to travel to somerset, Nettlecombe on the 9th July The Beginning of Marketing.
Pebble shape will become more rounded going from west to east — due to longshore drift the pebbles will hit the sea eseay as it travels so it will make the pebbles more rounded as the sharp, rough edges will chip off as it smashes against the sea bed. The national park is called Exmoor national park.
What has been the dominant direction of longshore drift in the past along Deal beach?
During the weekend we also carried out a study at Minehead to analyse the coastal management. For example, the prevailing wind along the Holderness Coast is north-easterly. This leads to a lack of beach material and therefore protection for the soft, boulder clay cliffs. As the pebbles from Gore Point are moved to Hurlstone Point by long shore drift, erosion is happening.
Pebble sizes are going to get smaller going from Gore point to Hurlstone point longshord due to longshore drift, the pebbles are going to hit the sea bed as it travels from West to East so parts of the pebble will chip off making the pebbles smaller as it gets to Hurlstone.
When the waves move back, pressure is released causing the water to expand.
Is porlock bay affected by longshore drift?
The headland has faults and cracks due to coastal erosion occurring at all times. The material was eroded from Gore Point and deposited at Hurlstone. During our stay in Somerset we visited many places, which include Porlock Bay, Hurlstone point lonbshore Porlock Weir where. However, the soft rock is less resistant to the effects of weathering.
