Question

Which landforms are formed due to the depositions of sediments carried by the river?
A. Flood leaves
B. Flood plains
C. Deltas
D. All of the above

Answer 1

Hint: Sediment is a solid material that moves to a new location and deposits, which can consist of rocks and minerals, remnants of animals and plants, and can be as small as a grain of sand or as large as a stone. Erosion is the removal and transport of rocks or soil.

Complete Answer:
Option A: Natural levees are found along the banks of major rivers, which are coarse, straight and parallel ridges along the riverbanks. The deposits of this channel are coarser than flood water deposits.
Option B: Deposition causes flood plains the way erosion causes valleys. A riverbed composed of river deposits is the active flood plain and the floodplain above the bank of the river is the dormant flood plain.
Option C: Delta is like alluvial debt, but develops in a different location: it is found in the estuary, the final location of sedimentary activity in the river. Coarser substances settle first and finer substances such as silt and clay are transported to the sea.
When a river is eroded and descends from a hillside with conveyed material to a level, without a slope/slope, the river loses energy to carry more of the conveyed material. Erosion, transportation, and sedimentation continue until the slope is almost completely flat, leaving a faint relief lowland.
Thus, the correct answer is Option D: All of the above.

Note: It must be noted that not all rivers form floodplains, levees, and deltas as the flow and speed of a river determine whether or not it will gather sediments and deposits. Fast flowing rivers do not gather silt and sediments, whereas slow moving rivers allow buildup.
