2. The act of removing the rock debris derived
by weathering process of external agencies is
called Erosion.
The removing the rock debris and deposited
elsewhere is called deposition
3. Factors influencing Erosion
Amount of water
Speed of the flowing water
Hardness of rock
Slope of the land
4. The inclined surface on both side of the river
are called valleys
The down cutting of the river is faster than
lateral cutting
Valley take v shape

6. Canyons are very long narrow valley
It found in Arizona in United states of

10. During the monsoon season ,when the river
overflow its banks there is flooding. As a
result of this , there is a deposits of silts on
the banks. This evolve as flood plains
11.
12. The speed of the river decreases when it
reaches the flood plains so the river twist and
turns which occur thus are called meanders
13. A crescent shape lake formed when a
meander of a river or stream is cut off from
the main stream
Changing course of river
14. When rivers brings materials along with it
which gets deposited near to the mouth of
the rivers the formations of a delta.
It look like the Greek letter delta (Δ)
Eg. Sunderban delta in India
