Aerial drone footage of chalk cliffs on the Isle of Wight, UK. The chalk was formed in the Cretaceous period, and is made up of the shells of tiny marine plankton, laid down at the bottom of the sea. The chalk beds were uplifted and deformed during the Alpine Orogeny, some 30-20 million years ago. During this process the horizontal beds were rotated so that they were nearly vertical, which accounts for the dramatic steep cliffs these coastal cliffs. They extend to The Needles sea stacks to the west. | |
