Frequently Asked Questions

How old are the white cliffs of Dover
The cliffs were formed by the erosion of chalk deposits from the Cretaceous. They have been estimated to be about 70 – 120 million years old.
Why are the white cliffs of Dover famous?
The White Cliffs of Dover are cliffs that form part of the coastline in England on the English Channel. They rise sharply out of the water, and you can see for miles either side of them. One reason why this area of coastline is so famous is that it often appeared in old war films. Dover has been used as a port since Roman times and especially since the Middle Ages when it became an important naval base.
What causes the white cliffs of Dover to be white?
These are made of skeletal remains of tiny planktonic algae that lived in the upper levels of the ocean. After the algae died, they sank to the bottom of the sea. Over millions of years, they were covered with more and more layers of rock. This squeezed them together until they were crushed into chalk. Over millions of years, the seabed was pushed upwards. The chalk was pushed up to where it is now on top of the sea. The chalk is made up of layers of white, flaky limestone rocks.
Can you walk along the white cliffs of Dover
