It is likely the area around the surviving lighthouse was inhabited in the early medieval period as archaeologists have found a Saxon cemetery here, and the church of St Mary in Castrowas built next to the lighthouse in the 10th or 11th century. These canyons formed over millions of years by water erosion slicing deep into the rock layers. Some birds nest in the cliffs due to the absence of predators in such rugged landscapes. By hydraulic action and abrasion, and the other processes of coast erosion, the base of the cliff is undercut to form a wave-cut notch.

Where cliffs are made from more resistant rock, wave-cut platforms are often formed. Waves striking these cliffs may have been formed hundreds of miles away and can be both huge and powerful. With global warming, the glacier began moving across the earth. Continuous lapping of water against the adjacent rocks leads to the formation of a vertically cut feature. The cliffs consist mainly of beds of Namurian shale and sandstone, with the oldest rocks being found at the bottom of the cliffs. A bluff is a steep cliff overlooking a plain or body of water, It may be composed of beach sand, or soil or a rock formation.

Located on Baffin Island in Arctic Canada, the cliff stands at 1370 meters (4500 feet). Weathering happens when natural events, like wind or rain, break up pieces of rock. When the rock above is left without any support, it collapses under its own weight, forming cliffs and stacks. They were formed over a 100 million years ago after layers of pulverized skeletons of tiny sea plants were deposited on the bottom of the ocean in a fine gray mud. It was established in 2000; it covers 458 square miles (1,186 square km) and has a range of elevations from 3,100 to 7,100 feet (945 to 2,165 metres). 3. Igneous rocks such as granite and basalt also often form cliffs. It is formed when the water rises along a slight but important slope due to some net shoreward transport of water when the waves move towards the beach. Cliffs and wave-cut platforms A wave-cut platform is formed when the following occurs: The sea attacks the base of the cliff between the high and low water mark. The major processes involved in the formation of a cliff are discussed below. Continuous erosion and weathering cause the cliff to enlarge and retreat more into the land. Especially common in cliffs occurring along coasts or large lakes, the repeated lapping of water against rocks as waves gradually wears the rock down, which can form cliffs over many thousands of years. The main contributors to sedimentary rock formation are erosion, precipitation, or natural weathering; as well as lithification and dissolution. Scientists have established that as the cliff agents invade an area, some rocks known as the sedimentary rocks become resistant to weathering. Weather weakens the cliffwhich causes it to collapse.
