Erosion: The White Cliffs of Dover

Erosion: The White Cliffs of Dover | Geography Education |
Thousands of tons of chalk from the famous White Cliffs of Dover have collapsed into the sea following a huge rockfall.


An excellent example of erosion and the processes that have shaped an iconic landscape.  The accompanying article has numerous pictures from a variety of angles that truly tell the story.

The White Cliffs of Dover serve as an natural icon for England. The cliffs are composed of chalk, giving them their white milky appearance. During the Cretaceous period, calcium carbonate from small coccolithophores and other phytoplanktons deposited on the bottom of the ocean and over time turned into chalk. While these cliffs have stood the test of time, it is important to remember that landscapes are always changing, especially now with drastic climate change. With increased amounts of erosion, weather anomalies, and acid rain, it will be interesting to see how some of these iconic landscapes are affected.
