    Study Notes

    Coastal Features: Erosional and Depositional Shores

    • Longshore currents along the coast move either southward or northward, depending on the location.
    • The California current is an eastern boundary cold current that moves southward along the Pacific coast.
    • The Gulf Stream is an open ocean current that moves in a northward pattern along the Atlantic coast.
    • Erosional shores, found on the west coast, have well-developed cliffs due to tectonic uplift.
    • Depositional shores, found on the east coast, are gradually subsiding and made up of unconsolidated sediment.
    • Erosional shores feature headlands, sea arches, coves, sea caves, sea stacks, blow holes, sea cliffs, marine terraces, and wave cut benches.
    • Marine terraces are former wave cut benches that have been uplifted due to tectonic activity.
    • Depositional shores feature barrier islands, bay barriers, spits, and tombolos.
    • Barrier islands are long offshore sand deposits parallel to the coastline.
    • Tombolos are exposed areas behind sea islands that are typically only visible during low tide.
    • Popular Florida beaches such as Clearwater, Miami Beach, and Fort Lauderdale are located on barrier islands.
    • Deltas are depositional features formed by the deposition of sediment from rivers into the ocean.
