The video explores marine processes that shape coastlines, including hydraulic action, abrasion, attrition, and solution. It begins with an introduction to the power of the sea, followed by detailed explanations of how waves impact cliffs through hydraulic action and quarrying. The video then covers abrasion, where rocks erode the cliff, and attrition, which smooths and rounds these rocks. Finally, it discusses the solution process, where seawater dissolves soluble particles, aided by acids in the water.
