The document discusses erosional and depositional landforms formed by sea waves. It describes how factors like wave size/strength, shore slope/height, and rock position influence erosional activity. Erosional landforms formed include sea cliffs, sea caves, arches, and stacks, which are the result of wave cracking, erosion of cracks, and the joining/collapsing of sea caves. Depositional landforms include beaches, which are temporarily formed by waves depositing sand and soil. In conclusion, sea waves cause significant morphological changes along shorelines through both erosional and depositional processes.

2. SEA WAVES
EROSIONAL AND DEPOSIONAL LANDFORMS

3. SEA WAVES
Undulations on the surface of sea
water .
By the actions of wind

4. FACTORS INFLUENCING EROSIONAL ACTIVITY
 The size and strength of the sea waves
 Height and slope of the shore
 Position of the rock on the shore

5. EROSIONAL LAND FORMS
 Sea cliff
 Sea caves
 Arches
 stacks

6. SEA CLIFF
 By the action of waves cracks occurred rocks
near shore
 Later cracks becomes larger and pieces fall
away
 Steep slope form called sea cliff

8. SEA CAVES
Formed due to erosive action of waves
Sea side are carved out form a hole
Hole is called sea waves

10. ARCHES
 Erosive and weathered activity by sea
waves
Sea caves are closed to each other
Joined together form arch shapes

12. STACKS
 The roof of the arches will collapsed
 By the continuous erosonal processes of
waves
 Remaining structure called stacks

14. DEPOSIONAL LANDFORMS
BEACHES
It is formed by the depositional work
of the waves
Sand and soil temporary deposited to
form beaches

16. CONCLUSION
By the action sea waves many
morphological changes are occurred on
the sea shore
It forms erosional and deposional land
forms like seacliff,sea and beaches ….etc.
