Why do rocky coasts exist?

Rocky coasts (high and low relief) result from resistant geology (to the erosive forces of sea, rain and wind), often in a high-energy environment, whereas coastal plain landscapes (sandy and estuarine coasts) are found near areas of low relief and result from supply of sediment from direct terrestrial and offshore …

What is zonation in rocky shores?

Zonation….. the variation in the distribution of organisms caused by differences in both biotic and abiotic conditions along an environmental gradient.
