  • The Karakoram is situated in the disputed region of Kashmir. It has more than sixty peaks above 7,000 m (22,966 ft), including K2, the second highest peak in the world 8,611 m (28,251 ft). K2 is just 237 m (778 ft) smaller than the 8,848 m (29,029 ft) tall Mount Everest. The range is about 500 km (311 mi) in length and is the most heavily glaciated part of the world outside of the polar regions. The Siachen Glacier at 70 km (43 mi) and the Biafo Glacier at 63 km (39 mi) rank as the world's second and third-longest glaciers outside the polar regions.
  • Vavul Mela is the highest peak of Sahyadri.Nilgiris join Sahyadri near Gudalur and marks the junction of Eastern and Western ghats
  • Anai Mudi is the highest peak of Western Ghat
  • Highest range of the Aravallis is Mt Gurushikhar.Mt Abu, Piplighat are also its part

  • he Aravali Range is the oldest mountain range in India
  • The Thar Desert (also known as the Great Indian Desert) is world's seventh largest desert;[15] it forms a significant portion of western India and covers an area of 238,700 km² (92,200 mile²).[15] The desert continues into Pakistan as the Cholistan Desert

  • Monsoon does not occur in Aravalli as it lies parallel to the air flow
  • Indian monsoon is orographic in nature
  • P Koteswaram-Worked on Monsoon
  • Southern Oscillation Index= Pressure in Tahiti-Pressure in Darwin.When there is Low pressure in Darwin, thus a positive SO Index,India gets maximum rainfall whereas low pressure in Tahiti causes negative SO Index and less rainfall in India.This is known as Walker phenomenon
  • Jet Stream Theory first given by M.T.Yin.The height of it is 12 km,it is in the troposphere.
  • Arabian sea branch of South West Monsoon causes more rainfall tha Bay of Bengal branch because of more volume of water and because India does not get full part of the Bay of Bengal branch of Monsoon
  • India's major areas in terms of height from the sea level in ascending order Calcutta-Chennai-Mumbai-Trivandam-Delhi-Jodhpur-Nagpur-Bangalore-Shillong-Leh
  • India's major areas in terms of rainfall Leh- Jodhpur-Delhi-Bangalore-Nagpur-Chennai-Calcutta--Trivandam-Mumbai-Port Blair-Shillong
