This document discusses the various agents of erosion that help shape landforms. The five main agents are running water, wind, glaciers, underground water, and sea waves. Running water creates V-shaped valleys and waterfalls through erosion. Wind erosion forms features like mushroom rocks and barchans. Glaciers leave behind glacial valleys and hanging valleys. Underground water erodes soft rock to form caves and sinkholes. Sea waves generate coastal landforms through erosion, deposition and other marine processes, including sea cliffs, sea caves, sea arches, and beaches.

2. EROSION

3. • The act of removing the rock
debris derived by the
weathering process of external
agencies is called erosion. It
helps to create new land
forms.

4. AGENTS OF EROSION
There are five agents of erosions.
1. Running water.
Running water create different landforms .V
shaped valleys and waterfalls are some of
them.

5. RUNNING WATER

6. A. V SHAPED VALLEYS.
The inclined surface on either sides of
the river are called valleys. Some valleys
become v shape due to the action of
erosion

7. V SHAPED VALLEY

8. B. WATER FALL.
• Water fall creates erosion in the
area which they fall. It falls
vertically down from steep places
in the hilly regions.

9. WATER FALL

10. 3. WIND
Another agent of erosion is the
wind erosion is more in dry areas.
It create mushroom rocks and
barchans.

11. MUSHROOM ROCKS

12. 3 GLACIERS
• Moving masses of ice or thick snow is
called glaciers. It create glacial valleys and
hanging valleys.

13. UNDERGROUND WATER
• Underground water produces the
erossional and depositional
landforms in those areas made of
soft rocks like limestone.

14. UNDERGROUND WATER

15. SEA WAVES
Strong sea waves cause changes on
the shore through the erosional and
depositional processes. The factors
influencing the erosional activity.
• The size and strength of waves
• Position of rocks on shores

16. SEA WAVE

17. A. SEA CLIFF
• Due to the force of the waves
cracks occur to the rocks which
are situated near to the shore.
This cause shore pieces fall away
into the ocean and sleep slopes
to form on the shores are called
sea cliffs

18. SEA CLIFF

19. B. SEA CAVES
Due to erosion by the waves weak
rocks by the side of the sea are
carved out and sea cave are
formed.

20. SEA CAVE

21. SEA ARCHERS
A sea arch is a natural opening eroded
out of cliff face by marine processes.
Some arches appear to have
developed from surge channels. The
support roof of the arch is know as
the keystone.

22. BEACHES
Beach is a land form alone coast of an
ocean or the edge of a lake or river. It
is a shore of a body of water,
especially when sandy .
