Study Notes
Kerala and the Western Ghats
- Kerala's Ghats consist of isolated mountains, allowing rain-bearing winds to pass over the leeward side without precipitation.
- Slope gradient influences precipitation; gentle slopes in Karnataka facilitate cloud formation through the collision-coalescence process.
- A gradual slope allows more sunlight absorption and heating, enhancing convection compared to steeper slopes in Maharashtra and Kerala.
- Continuous mountain ranges, like those in Karnataka, create more barriers to rain-bearing winds than isolated mountain formations in Kerala.
- Heavy rainfall areas can be located up to 50 km away from mountain summits due to increased moisture depth at mountain foot.
Karnataka’s Administrative Divisions
- Bengaluru Division: 49,697 sq km, 36.8% population, 52 taluks.
- Belgavi Division: 54,513 sq km, 24.21% population, 49 taluks.
- Gulbarga Division: 44,108 sq km, 18.46% population, 31 taluks.
- Mysuru Division: 43,473 sq km, 20.55% population, 44 taluks.
- Overall Karnataka: 191,791 sq km, population of 61,130,704, comprising 176 taluks.
Geographic Relief Features of Karnataka
- Mysuru Plateau spans a large part of Karnataka, extending into Tamil Nadu and Andhra Pradesh.
- Northern Karnataka features part of Maharashtra Plateau, showcasing diverse topography from coastal plains to elevated Malnad regions.
- Eastern Karnataka is predominantly a monotone plateau, with rolling hills in the southern areas.
- The state has varying elevation levels, typically ranging from 300 to 1,350 meters above sea level.
Key Peaks and Geography
- Mullaiyyangiri is the highest peak at 1,913 meters in Chikkamagaluru district; Kuduremukh follows at 1,892 meters.
- The Western Ghats display vertical cliffs along the coastal plain while eastern slopes are gentler, merging with the maidan region.
- The Western Ghats are primarily an upthrown block; the western coastal area is a downthrown block characterized by undulating plains.
Geological Origin
- The Western Ghats originated from normal faulting and are linked with volcanic activity in the region.
- Historically, the igneous rocks and separate landforms resulted from the drift of the Indian subcontinent towards the northeast.
- The Miocene period marked significant geological action, leading to the distinct escarpment along India's western margin due to marine erosion and later regression.
- Coastal plains have developed into wave-cut platforms, with westerly drainage patterns emerging over time and capturing eastern drainage rivulets.
