 The rising land beside the coast, between the valley and the eastern cliffs, is known as'The Downs' (no relation to the North or South Downs). This area has been named a Site of Scientific Interest and a Special Protection Area for Birds. The whole of the north east Kent coast has been designated a Site of Special Scientific Interest. The geology of the town consists mainly of London Clay, overlaid with brickearth in the west. The sand and clay of The Downs are subject to landslips.
