Holderness and erosion

Holderness and erosion


Eustatic change is when sea level changes through external factors. A well-known one happened at the end of the ice age. Where Glacial Valleys melted to form Rias and Fjords and sea levels rose.

Isostatic change on the other hand is when land itself rises due to many factors. At the end of the ice age the ice that caused parts of the earth to sink has melted allowing that part of the earth to rise again whilst the other part now faces flooding and sinking. (Think of it as a slow seesaw.)



Many factors have led to and increased erosion in Holderness. The factors include: Fetch, the type of soil and regular geology.

Holderness has a gigantic swell, ranging from the northern sea to the Atlantic. For this reason Holderness is subjected to powerful waves hitting its shores. Other factors add to it. Those being the depth of the sea floor and the fact that Holderness coast is deeply enclosed preventing waves from dissipating their energy.

Also the type of rock affects the stretch of Holderness. Holderness has 3 types of soil:

-boulder clay.



Withernsea for instance has an abundance of boulder clay soil which erodes two meters per year . Hornsea and Mappleton have chalk which forms stacks and heads.

Factors that have caused those to erode are:


-Hydraulic action.

As well as other range of Physical, Chemical and Biological weathering.

On the other hand there are also a range of other factors such as the Eustatic and Isostatic changes.
