How has the landscape developed along the coastline between Prawle Point & Start Bay in Devon?

Introduction

How has the landscape developed along the coastline between Prawle Point & Start Bay in Devon? Introduction During my trip to Devon, I stayed at Slapton village, where I hiked and observed different points of Devon's coast such as Gammon Head, Prawle point, Lange stone point, sharper's head, start point, hall sands ect..., and analysed how the physical and human processes have changed the landscape along the coastline between prawle point, and Start Bay. My aims for this coursework are: * To describe & explain how the landscape has been affected by geomorphic processes between Prawle Point & Start Bay. * To describe & explain how the landscape has been affected by human activity between Prawle Point & Start Bay. Location of both Slapton, and Barkingside I was asked to compare Slapton village to Barkingside, where I live. After going to the Devon, I now know about both towns. Slapton village is based in south west Devon, which is located in south west England, The nearest city is Plymouth which is 29.2 miles - about 52 minutes away from Slapton. Whereas Barkingside is Based north east London, Which is located in South east England. The nearest city is London which is 13.9 miles - about 36minutes from Barkingside. Comparing the population of Devon(Slapton) and Essex(Barkingside) From going to Slapton village, I noticed that the population was very sparse, which means there were not many people there. Barkingside, on the other hand, has a very dense population. I can compare the two populations by showing a population structure for each region. Devon Essex Total Population 704493 Total Population 1310835 As we can see from these population pyramids, the two regions show some similarities, with them both having the same shape of population. We can see that theirs is low infant mortality, as the numbers of 0-4's hardly drop, from 5-9 ECT.... We can also see a clear distinction in both population pyramids in that; it is the most around '35-39' - '55-59'. ...read more.

There were also many hills, which tells us that the relief was also high, therefore making the relief as a whole in Slapton uneven. Because of the many hills in Devon, this makes it good for pastoral farming, which is sheep grazing, which may be a reason why Slapton has so many cattle. However, arable farming wouldn't be suitable for Slapton, as the rain water would leech the nutrients out of the soil, while running down the hill, making it harder to grow crops. Also, because of its hills on the coast, it makes it a bad place to build on, as over time the coast would erode the land, and eventually the buildings would fall into the water, as the cliff's break However in Barkingside, the relief is very even, with roads with few slopes. The land is very flat and low lying. This is why Barkingside has many buildings, as flat low lying land is good for building on. It also would make it good for arable farming, as the flat low lying land would be good for growing crops, as the nutrients could not be drained away by the rain water. I can now draw relief Diagrams for both Slapton, and Barkingside. As we can see from the Relief graphs, there is a clear difference in the relief of the 2 locations. We can see that Slapton's relief peeks at 120 metres above sea level, and its lowest point of relief is at 0, therefore we can say the relief from Slapton is jagged, and un-even. However, we can see from the relief of Barkingside, that it peeks at 40 metres above sea level, and has its lowest point of relief at 20, therefore we can say that Barkingside's relief is smooth, and even. Comparing the climate of Devon (Slapton), and London (Barkingside) I can now compare the types of climate in both regions, by displaying Climate graphs, and explaining them. ...read more.

Conclusion

Over time the cliff becomes top-heavy, and breaks off, and falls into the sea, due to lack of support. A wave-cut platform is created. Over time, due to the ice age the sea levels have dropped; causing langerstone point to look like it is today. Where the abandoned cliff was now, was once a raised beach, as the sea levels covered everything else. If sea levels were to rise, due to ice caps melting, from global warming, then the wave cut platform would be part of the sea bed, the raised beach would then become a wave-cut platform, and then abandoned cliff would become a cliff again. Hypothetically, everything would go down a level. However, if the sea levels were to drop again; from another ice age, in contrast, everything would go up a level, so the wave cut platform would then become a raised beach, and the sea bed would then be exposed to erosion, which would over time, cause it to become the new wave-cut platform. Sharpers Point We then went to Shaper's head (Grid reference - 78, 8, 35, 8 - from the south Devon OS explorer map - it is located to the right of Langerstone point), and looked at how the landscape has formed due to physical processes. In Sharpers head, lies Sharpers cove, which is a very unstable cliff, formed from due to deposition. This deposition happened at the end of the last ice age, hence the term ice age cliff, which is what sharpers cove is. Large and small rocks were carried in ice, which was transported over seas, by meltwater. The rocks were then deposited when the meltwater met the sea. The cliff is entirely made up of sediment rock, hence why it is so unstable, and the rocks can easily be pulled out the cove, as they were deposited. The rocks also all point in the same direction, which shows us that they all came from the same direction, which was from the sea. ...read more.
