The strata have been so heavily folded during the Alpine Orogeny that the chalk is near vertical. This chalk outcrop runs through the centre of the Island from Culver Cliff in the east to the Needles in the west, and then continues under the sea to the Isle of Purbeck, forming
Guglielmo Marconi Edouard Branly and used in Lodge's experiments, that changed resistance when exposed to radio waves. In the summer of 1894, he built a storm alarm made up of a battery, a coherer, and an electric bell, which went off when it picked up the radio waves generated by lightning. Late one night, in December 1894, Marconi demonstrated a radio transmitter and receiver to his mother, a set-up that made a bell ring on the other side of the room by pushing a telegraphic button on a bench. Supported by his father, Marconi continued to read through the literature and picked
