About this part of Britain was submerged by a shallow sea, the sea bottom was made of a white mud formed from the fragments of coccoliths (skeletons if tiny algae), then the m…ud became chalk
Because they are made from chalk (calcium carbonate) which is a white material. The truth is that they are really not that white. If you looked closely you would find that s…ome parts are absolutely full of plant growth and flint. The effect that causes them to be "so white" also has to do with reflection of light. The calcium carbonate form coccolith structures that can reflect light. The (south-)western orientation of the cliffs in combination with the rising sun generate the reflection and "light up" the cliffs.
There are at least seven white cliffs, known as the Seven Sisters.
Formed by coccolithophores: single-celled planktonic algae whose skeletal remains sank to the bottom of the ocean and, together with the remains of bottom-living creatures, fo…rmed sediments.
The white cliffs of Dover began eroding at the end of the last ice age, around 10,000 years ago. Before that they were part of a large system of rolling hills made of chalk.
The White Cliffs of Dover are on the southeast coast of England.
A cliff face in the county of Dover (England) where the rock underneath the grass is shown on the coastline. The rock is limestone.
Because they are chalk cliffs and coloured white
The white cliffs of Dover are so named because they are made of chalk.
On the southeast coast of England near the town of Dover.
The White Cliffs of Dover belong to the North Downs Formation along the English coastline. They face the Strait of Dover and France and are along the English Channel.
