Natural+Processes

Remember when you write about a process you need to illustrate the series of events that make it a process. That means that if you are looking at coastal erosion and you are talking about corrasion for instance then you would need to talk about the fact that sediment gets suspended in the water and when the waves crash against landformsd then so does the sediment breaking small particles off it which in turn gets washed away by the water. This illustrates that coastal erosion in the form of corrasion is not just a thing but a series of related events and hence a process.

The Columnar Basalt is a rather unique landform that exists at Karitane because of the processes that created it. Can you remember the three processes that have created this landform and in what time frame? This would be a really good landform to look at when comparing it with other landforms like the 'Mother & Child' stacks. Don't just think about how it got there, but what is happening to it right now to change what is there? Click for a revision poster.





With stop two you had quite a lot of work to do. This is really useful to mention in a questions about spatial variations. Why were the angles of the beach different, what about the sand profiles? Click for a [|revision poster].



The cliff is a good example of a phenomena that brings all three natural processes together easily. So, when you look at this picture think about what eveidence you can see of coastal erosion, coastal deposition and transportation all operating and what elements caused them. This site provides a very simple visual representation of how cliffs erode.



The 'Mother & Child' stack is one of the most notable landforms (or phenomena) that exists at Karitane. It shows evidence of coastal erosion by at least two main elements. At the same time there is evidence that this is not rapid - can you work out why?

If you are given a question on temporal variations the ''Mother & Child' is a good example to use because you can see (especially at low tide) how it might have looked before all the erosion happened. Also remember that in this question you can also talk about how all this material got there in the first place, you might even speculate what will happen to the phenomena in the future.

The 'Twistie' stack is a good penomenon to contrast with the 'Mother & Child' stacks for several reasons. The first being that they are so close and this gives a good spatial variation - they are similar landforms, but are quite different to look at.

The sediment of the two landforms is quite different. The 'Twistie' shows signs of corrosion as well as other methods of coastal erosion. This phenomenon is also not as exposed to the southerlie winds that plague the coast as well. Does this influence the erosion that does take place?

Here is a great video by David Rogers that does a wonderful job of explaining longshore drift and how to draw a really useful diagram about it.

Designed for students sitting their GCSE, this site gives some general notes about coastal processes and then there is an opportnity to test yourself to see how well you have done.
