What is Erosion ? THE COMBINED ACTION OF TRANSPORTATION AND BREAKING DOWN OF ROCKS IS KNOWN AS EROSION .

INDEX

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

Agents of Erosion

INDEX

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

A Waterfall…

INDEX

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.

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.

Mushroom Rocks…

INDEX

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.

Marine Erosion…

INDEX

Man- Made ErosionMan 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..
