These things are long and narrow accumulations of sediments, mostly sand, that lie parallel to and separate from the mainland.
To explain the formation of these things, Miles Hayes developed the transgressive-regressive interfluve hypothesis. Prograding examples of these things have the characteristic shape of a drumstickin the sense of a chicken leg. Retrograding examples usually undergo "rollover," which creates a washover terrace and causes them to migrate. In New England, a majority of these things originated from the elongation of (*) spits. These things occur in chains separated by tidal inlets and can shelter lagoons, marshes, and estuaries. These things are long and narrow accumulations of sediments, mostly sand, that lie parallel to and separate from the mainland. For 10 points, name these offshore environments whose examples include the Outer Banks.
