The water remains in the left cylindrical part, it is called
cylindrical lake. Sometimes the river
seems to flow out of its banks. The
result is the deposition of silt and other substances in nearby areas. These are called flood plains. This forms a flat fertile floodplain, when large
silt-soil deposits on both sides of the river form several long and low
elevation patterns, called natural embankments.
The flow of the river slows down until the sea reaches the formation of
a cylindrical lake Nagakar Sarovar. And
the river splits into several streams which are called branch flood
plains. Here the speed of the river
slows down It happens that it starts to
deposit silt, sand, clay and other objects that have been brought with it. Each branch forms its own mouth.
The amount of deposition of all the mouths
forms the flood plain and embankment of the delta. Function of ocean waves: The erosion and
deposition of ocean waves form the landforms of the coast. The waves of the ocean constantly collide
with the rocks causing cracks. Periodically
it becomes larger and wider. It is
called Samudrigufa. As the caves get
bigger, only the roof remains. Which
forms the coastal (arch) arch. The
constant downpour also breaks down the roof and leaves only the walls. This wall-like terrain is called a
'stack'.
The high rocky shores that rise
almost above sea level are called seawalls.
Sea waves form deposits on the shore to form sea pulleys. Glacier Function: Glaciers form glaciers in
glacial mountainous areas. Glaciers
erode round clay and rocks from the lower solid rocks to form a distinctive or
globular terrain, forming a U 'shaped valley through glacier erosion. The melting glaciers form a tarn in the
ravines in the mountainous areas.
Glacier-like objects such as small and large rocks, sand and gravel are
deposited to form a hilly ‘drumlin’ land in the middle of its flow. Wind function: In desert, wind is the main
factor of erosion and deposition, the wind settles the lower part more easily
than the upper part of the rocks, hence the base of such rocks is narrow and
the head is large. The desert has
terracotta-shaped cliffs, commonly called terrestrial rocks. This form of land is called Bhuchatra Khadak,
which carries sand from one place to another with the speed of wind. When this type of sleep is found in the
deserts of Rajasthan, it is carried away, when these soil particles are
deposited in a large area, it is called ‘loess’. Large loess deposits are found in China. DARO sand dunes
