INTRODUCTION
• The act of removing the rock debris derived
by the weathering processes of external
agencies is called erosion
• Factors like running water ,wind, glaciers ,sea
waste all aid in erosion process.

“V” SHAPED VALLEYS
• The inclined surface on either sides of the river are called valleys. The down cutting of the rivers is faster than the lateral cutting of the valleys and due to this, the depth of the river increases. They cause the valleys to take the “V” Shape.

WATER FALL
• Water falls vertically down from steep places in the hilly region. This kind of flow of the rivers is called water falls.

GRAND CANYON
• The Grand Canyon is situated in Arizona in the United States of America. This was formed by the erosive action of Colorado river.

FLOOD PLAINS
• During monsoon, when the river overflows its banks there is flooding. As a result of this, there is a deposit of silt on the banks. This evolves as flood plains.

CONCLUSION
• Erosion refers to the actions of exogamic
processes which remove soil and rock from
one location on the Earth's crust
then transport it to another location where it
is deposited. Eroded sediment may be
transported just a few millimeters, or for
thousands of kilometers.
