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 landform 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.
New crust typically forms from separating plates, so it would be A: divergent boundary.

Erosion, cause it causes only negative consequences
