The breaking waves erode, or wear away, the rock at sea level bit by bit, forming sea stacks. Sea arches form when powerful waves pound into the rock from both sides of the headland. The waves eventually break right through the headland, creating an arch. Deposition is the process by which sand and sediment is transported to the coast, often times a spit is created as sediments is moved in a zigzag pattern from long-shore current and prevailing winds.
A seismic interpretation s needed to understand the data that is generated from the earthquake waves to understand the subsurface observations. The seismic attributes like the amplitude, phase, wave frequency are used in interpretation but most of them are based on attributes of amplitudes.
Instantaneous frequency is used to determine the thickness in beds and recognition through the Subtle faults and the Stratigraphic pinch outs.
Seismic stratigraphy is another field that is based on the depositional bedding planes of the earth's rocks mass fixed in there geologic history. Various types of techniques exist in this framework <u>like flooding surfaces maximum flooding surfaces and the erosion surfaces.</u>
