A series of terraces along a river. The oldest terraces (T1) are higher standing than the younger terraces (T3). The present floodplain (T4) will soon become the youngest terrace surface as the river incises. Terraces can be formed in many ways and in several geologic and environmental settings. By studying the size, shape, and age of terraces ...
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 ...
Fluvial terrace – Elongated terraces that flank the sides of floodplains and river valleys; Gorge – Deep chasm between cliffs; Gully – Landform created by running water and/or mass movement eroding sharply into soil; Levee – Ridge or wall to hold back water; Marsh – Low-lying and seasonally waterlogged land
Nested fill terraces: Nested fill terraces are the result of the valley filling with alluvium, the alluvium being incised, and the valley filling again with material but to a lower level than before. The terrace that results for the second filling is a nested terrace because it has been “nested” into the original alluvium and created a terrace.
The marine terrace's "ecological staircase" of Salt Point State Park is also bound by the San Andreas Fault. Along the coasts of South America marine terraces are present, [44] [54] where the highest ones are situated where plate margins lie above subducted oceanic ridges and the highest and most rapid rates of uplift occur.
