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 ...
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.
Sediments underlying fluvial terrace exposed in cutbanks along the Manú River, Peru. In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp". The tread and the ...
Baymouth bar – low and narrow strip of alluvial land made from sand or pebbles; Beach – Area of loose particles at the edge of the sea or other body of water; Raised beach – Emergent coastal landform; Beach cusps – Shoreline formations made up of various grades of sediment in an arc pattern

A so-called "cathedral" mound produced by a termite colony. Structures built by non-human animals, often called animal architecture, [1] are common in many species. Examples of animal structures include termite mounds, ant hills, wasp and beehives, burrow complexes, beaver dams, elaborate nests of birds, and webs of spiders.
Dendritic happens to be the most common, occurring when the underlying stratum is stable (without faulting). Drainage systems have four primary components: drainage basin, alluvial valley, delta plain, and receiving basin. Some geomorphic examples of fluvial landforms are alluvial fans, oxbow lakes, and fluvial terraces.
The alluvial plain at piedmont is composed of Alluvial fans which can be found in this area, and which are located at the foot of the rocky mountains. [4] The size of this belt depends on the amount of runoff and weathering materials from the rocky mountains. [4] Old alluvial fans are covered with eolian loess. Further from the rocky mountains ...
