  3. Glacial landforms Masses of ice moving as sheets over the land are called Glaciers Movement is slow ; few centimetres a day U shaped valley Glaciers move basically because of the force of gravity. " Erosion is carried through the mechanism of abrasion and plucking e Large parts of well jointed rocks are detached by moving glaciers.That is called plucking


  4. Erosional landforms Cirque: most common of landforms in glaciated mountains. e Ho rse shoe shaped glacier depression e If this is filled with water it is called Tarn Lakes i.e cirque lake Arete: Narrow mountain peaks formed due to formation of a series of cirque on different sides of a hill


  5. Erosional landforms Horn: Ridge that acquires a horn' shape when the glacial activity cuts it from more than two sides. o Hanging valleys: Formed because of different rates of cHanging valleys: Formed because of di erosion The tributary valleys are left high above the main valley, hanging on the edges. . Fiords: Glacial troughs occupied by a sea. Eg: norway


  6. Depositional landfornm Depositional landforms Glacial deposits are unstratified called as Tills. Moraines: Ridge like depositional feature of glacial till. if deposited at the end - Terminal moraines if deposited at either side of glacier - lateral moraines if deposited at the internal margins of two glaciers Medial moraines e Drumlins: Inverted boat or egg shaped deposition of glacier eg: Ireland - basket of egg topography


  7. Depositional landfornm Depositional landforms Eskers: long narrow and steep sided ridges of stratified sand and gravel Deposited by sub glacier or melt water stream outwash Plains: plains at the foot of the glacial mountains # 1 silt sand and clay Formed in the terminal stage of a continent
