The subject of geologic shoreline features encompasses a wide range of important elements. 12 Coastlines – An Introduction to Geology. Shorelines are divided into five primary zones—offshore, nearshore, surf, foreshore, and backshore. The offshore zone is below water, but it is geologically active due to flows of turbidity currents that cascade over the continental slope and accumulate in the continental rise. 12.2: Shoreline Features - Geosciences LibreTexts. From another angle, many different erosional and depositional features exist in the high energy of the coast. The coast or coastline includes all parts of the land-sea boundary area that are directly affected by the sea.
In this context, this includes land far above high tide and well below normal wave base. Geologic Shoreline Features - YouTube. Instructional video showing examples and discussing the formation of the following: spits, baymouth bars, sea arches, sea stacks, tombolos, wave-cut platform... Coastal Geology: Shorelines – Geology 101 for Lehman College (CUNY).
As the coastal cliffs collapse, the shoreline recedes inland. The speed at which this happens depends, in particular, on the strength of the surf, the height of the cliff, the frequency of storm surges and the hardness of the bedrock. In this context, beaches and Coastal Landforms - Geology (U.S.
National Park Service). A variety of factors—including wave energy, tidal range, sediment supply, beach materials, continental-shelf slope and width, and past geologic history (e.g., glaciation, volcanism, and plate movement)—characterize coastal environments. Furthermore, shoreline Features - CliffsNotes. Wave action eventually straightens and smoothes the coastline.
The headlands receive the greatest force of the waves, and the bays are the most sheltered. Building on this, the headlands are broken down more quickly than the bays, and the eroded material is deposited in the coves. Reading: Shorelines | Geology - Lumen Learning. These geomorphic features compose what is called the beach profile.
Additionally, the beach profile changes seasonally due to the change in wave energy experienced during summer and winter months. Chapter 17 Shorelines – Physical Geology – 2nd Edition. Explain why some coasts are more affected by erosion than others and describe the formation of coastal erosional features, including stacks, arches, cliffs, and wave-cut platforms Geology of Shorelines | US Environmental Protection Agency. Building on this, shorelines can vary dramatically in their forms and compositions. Some shorelines are narrow with beaches formed from rounded or flattened cobbles and pebbles; some are wide and covered in a layer of sand or broken shell fragments; and still others are steep cliffs with no beach at all.
