|The White Cliffs in Dover, England|
Its chalk cliffs are stretching for several hundred meters along the coast in the English county of Kent. White Cliffs of Dover are located at the narrowest point of the English Channel and it is only in 34 kilometers away from France. Locals say that during the good weather one can see solid white line of chalk hills of Dover.
This fact proves that in the past the UK was easily accessible from the surface of the sea to continental Europe. And the White Cliffs of Dover were long time ago a powerful protection against unexpected enemies. That’s why the historical value of these mountains is huge. For seafarers, these rocks have always been a guide indicating the approach of the English coast.
Mountains consist mainly of soft white chalk fine structure, hence the snow white cliffs. It consists of calcium carbonate - the remains of plankton and algae. In the Cretaceous period millions of tiny creatures living in the shells, died and remained lying on the seabed. Thousands of such layers are compressed slowly, thus creating a continuous white platform.
After many, many years the water was gone, it left the mighty cliffs of white color which we are now able to enjoy. By the way black specks in the rocks – are nothing like a flint.
But the power of water cannot be beat. It gradually destroys cliffs force of the waves. Bringing water sand, pebbles and stones, eroding cliffs, forming cracks and depressions, the sea water causes irreversible damage to the rocks Duvra.
The cliffs are composed of soft chalk - just a brittle material, notwithstanding strong "attacks" of water and wind.
In 2001, a huge white boulder fell into the deep from giant mountain. And in March 2012, it took a new breakaway that hit in the Strait of Pas-de-Calais. Now the rains were the perpetrators of this destruction.
So hurry, while we are living in the time when there are still so many natural wonders remaining you are lucky to see.
