Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
Marine geology also has many applications on the subject of offshore energy development. [55] Offshore energy is the generation of electricity using ocean-based resources. This includes using wind, thermal [clarification needed], wave, and tidal movement to convert to energy. [56]
Coastal sediment transport takes place in near-shore environments due to the motions of waves and currents. At the mouths of rivers, coastal sediment and fluvial sediment transport processes mesh to create river deltas. Coastal sediment transport results in the formation of characteristic coastal landforms such as beaches, barrier islands, and ...
Coastal sediment transport (a subset of sediment transport) is the interaction of coastal land forms to various complex interactions of physical processes. [1] [2] The primary agent in coastal sediment transport is wave activity (see Wind wave), followed by tides and storm surge (see Tide and Storm surge), and near shore currents (see Sea#Currents) .

As well as dominant drift direction, spits are affected by the strength of wave-driven current, wave angle and the height of incoming waves. [7] Spits are landforms that have two important features, with the first feature being the region at the up-drift end or proximal end (Hart et al., 2008).
A marine terrace represents the former shoreline of a sea or ocean. It can be formed by marine abrasion or erosion of materials comprising the shoreline (marine-cut terraces or wave-cut platforms); the accumulations of sediments in the shallow-water to slightly emerged coastal environments (marine-built terraces or raised beach); or the bioconstruction by coral reefs and accumulation of reef ...
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
Ocean attrition causes shorelines to retreat and ocean depths are increased to the depth of the wave base. [23] Attrition erosion of the coast in Langeland, Denmark, shows how high impact energy of sediment particles affect ocean-land contact points. The rising of sea levels has led to an increase in coastal erosion. This causes concern to ...
