LONGSHORE DRIFT ESSAY

Minehead has more people employed, as tourism is its main source of income. Waves are biggest and have the most energy when the wind is strong and has been blowing for a long time. However, the soft rock is less resistant to the effects of weathering. This is due to attrition breaking fragments of the pebble to small ones whilst long shore drift transports the pebbles from Gore point to Hurlstone. Attrition and abrasion erosion makes the pebbles rounder and smaller as it travels through its journey from west to east. Minehead attracts tourists to the area because it is near to the coast and has lovely beaches. Below is a list:.

Red Marl is an example of a soft rock. Longshore Drift littoral drift Longshore drift is a process responsible for moving significant amounts of sediment along the coast. This is illustrated in the photograph below where a large rock groyne at Mappleton stops the supply of new beach material. We visited Gore Point which is west of Porlock Bay. As the result longshore drift transports material from the beach to the south of the groyne and is not replenished. This is due to attrition breaking of parts of pebbles to make it rounder, smoother and smaller at Hurlstone while long shore drift transports the pebbles.

The population of minehead is 14 Pebble shape will become more rounded going from west to east — due to longshore drift the pebbles will hit the longhore bed 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 pebbles are distributed evenly at Gore Point due to abrasion breaking up bigger rocks to form smaller ones. Bays and headlands are formed after esssay erosion and they are situated along the coast where there is both hard and soft rock.

Porlock Bay is in the rdift of Somerset and Bristol is the nearest major city. In my investigation, I could have improved the way i collected the data or how i could have further investigated coastal processes at Porlock Bay. We recorded all the measurements down.

We measured the pebbles using systematic sampling. You can see that both Hurlstone and Ddrift Point both have the first highest facet. This usually occurs in one direction as dictated by the prevailing wind. The amusement park, Butlins drives some of the economy and attracts many tourists to the area. The video below shows the movement of beach sediment at Mappleton, Holderness Coast.

The crack become big and is eroded longzhore form a cave due to hydraulic action, attrition and abrasion. This is because it is dangerous as if the stones hit someone, they could be seriously ddift.

This is illustrated in the photograph below where a large rock groyne at Mappleton stops the supply of new beach material. Red Marl is an example of a soft rock. Waves are biggest and have the most energy when the wind is strong and has been blowing for a long time. If i took measurements from points between Gore Point and Hurlstone, I would have got a more wide range of results which would make my results more accurate.

Is porlock bay affected by longshore drift?

The headland has faults and cracks due to coastal erosion occurring longhsore all times. However, the soft rock is less resistant to the effects of weathering.

I measured 30 pebbles in total, picked 1 pebble at every one meters for 30 meters. I have presented my class results on a bar graph. This is due to attrition and abrasion breaking fragments of pebbles as they travel from West to East due to the process of long shore drift. The backwash then brings the material back down.
