3. What is Erosion ? The combined action of Transportation and Breaking down of Rocks is known as Erosion . INDEX

4. Some Agents of Erosion Some common agents of Erosion are :- Action of Running Water. Action of Moving Ice. Action of Wind. Action of Waves. Man-Made Erosion INDEX

5. Agents of Erosion INDEX

6. Action of Running Water… Water is the Most Powerful Agent of Erosion. Both Surface and Groundwater act as Agent of Erosion. Groundwater creates underground surfaces like-Caves. Water running on land surfaces creates land surfaces like- Deltas. INDEX

7. A Waterfall… INDEX

8. Action of Moving Ice… Ice is also a Powerful Agent of Erosion. A large mass of Moving Ice is called Glacier . When they move they carve their own valleys .i.e. U-Shaped and V-Shaped valley. Like Rivers, Glacier break and carry away Rock Fragments. INDEX

9. A Glacier….. INDEX

10. Action of Wind… Like ice and water , Wind too erodes , transports and deposits rocks materials. The Action of Wind is more prominent in Arid and Semi-Arid regions. The flow of Wind can change the shape and size of Rocks . INDEX

11. Mushroom Rocks… INDEX

12. Action of Waves… In Coastal areas, Sea is constantly eroding old landforms and creating new ones. The Marine Erosion is also a type of Wave Erosion. The Marine Erosion creates landforms such as- An Arch, A Sea Cave, etc. INDEX

13. Marine Erosion… INDEX

14. Man- Made Erosion Man is also responsible for erosions. Today man is the strongest agent of erosion . We see several examples in our daily life. Cutting mountains and big rock bodies for road making, building construction and to make farmland etc. Mining for precious metals like gold, silver, copper etc., precious minerals like diamond, garnet etc and construction material like marble, granite etc is also done..
