Erosion characterizes these high-energy environments, which are typically located on active margins with narrow continental shelves (on account of subduction). Spits - The Formation of a Spit - GCSE Geography - YouTube Headlands are formed from hard rock, that is more resistant to erosion, such as limestone, chalk and granite.
