The three houses each accommodate three AIRs and a Headlands Intern. Sea caves are formed by the power of the ocean attacking zones of weakness in coastal sea cliffs. Soft rock bands, such as clay and sand, are weaker, so they can be quickly eroded. Broadly, the coastal landforms can be divided into two groups, those formed due to erosion and those formed due to deposition. The ocean's "dynamic" topography tells oceanographers the speed and direction of ocean currents in the same way that maps of atmospheric pressure are used by meteorologists to calculate the speed and direction of winds. Differential erosion creates headlands and bays, in which rocks along the coast are formed in alternating bands of various rock types, such as sandstone and clay, that meet the coast at right angles.
