Where the direction of the shore inland re-enters, or changes direction, for example at a headland, the longshore current spreads out or dissipates. The rocky Maine coastline is emergent because the land isrising faster than sea level. Waves that arrive in a direction other than obliquely along the spit will halt the growth of the spit, shorten it, or eventually destroy it entirely.[4]. When does a spit cross a bay it forms a bay?
