You are walking on a beach and see a split. Explain how a split could have formed from a rocky headland.
kirza4 [7]

Hello, Lindaparker, a spit  could form from a rocky headland where prevailing winds would blow at an angle to the rocky headland, gradually depositing sand and shingle at that place. A spit is a permanent land form resulting from marine deposition and wind deposition. It is usually a long and narrow accumulation of sand or shingle with one joined to the land and the other end projecting at   a narrow angle out into the sea. Salt marshes sometimes form on the sheltered side of a spit.
