Explain the major glacial landforms created due to immense mass movement of glaciers.
Introduction
Glaciers move slowly but due to immense mass create unique landforms.
11 words
Main Body
EROSIONAL LANDFORMS:
1Mountain Home - is headward erosion from three sides
2U-shaped valleys - is due to glacial erosion → glacier meets → U-shaped valleys life
3Unique - bowl shaped indentation
4Hortic Sign - card between two glaciers
DEPOSITIONAL LANDFORMS:
1Moraine - glacial materials built up end of glacier
2Esarine - silt glacial stream - water
3Alewomen - is front, flat end of glacier
4Glacial lakes & ponds - tarn lakes
Factors contributing to variability:
1Pressure gradient & temperature - by SJ weak, less variety of Tibetan plateau's jet monsoon
2Indian ocean dipole - difference in sea surface temperature between western & Indian ocean. Positive IOD - good example. Negative IOD - poor example
3ENSO - periodic warming of sea surface temperature amidst western Pacific - off coast of Peru - late rainfall
4Jet stream - withdrawn of westerly subtropical jet causes burst of monsoon
5Topography - North Cool - trap rain clouds
Multidimensional Impact:
1Lifetime of agriculture - almost 15L of Indian agriculture depends
2Recharge of aquifers, rivers & dams to store water for stressed 1 days
3Dams construction (Bhakra kept & Beas)
4Surface on implicater - poor rainfall can cause greater valuable price levels of vegetables & grain products
5Higher prices of tomatoes @ 100₹/kg
11Reduces temperature - case pressure of arriving temperature of May & June is flood productivity
8North Coast monsoon - good for mango, plantation (TN), coffee (Kerala)
