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.
