Geography of India and Andhra Pradesh
What this domain tests
This domain covers India's physiography, climate, monsoon, rivers, soils, vegetation and resources, then applies them to Andhra Pradesh: coastal plains, Eastern Ghats, Rayalaseema plateau, river basins, ports and cyclone risk.
Core concepts
- India has Himalayan mountains, northern plains, peninsular plateau, coastal plains and islands.
- The southwest monsoon brings rain from June to September; the northeast monsoon brings rain to coastal Andhra and Tamil Nadu from October to December.
- AP's major rivers are the Godavari, Krishna, Pennar and Tungabhadra. The Godavari is the longest peninsular river.
- The Eastern Ghats are discontinuous and are cut by river valleys; they influence rainfall and drainage.
- Major ports include Visakhapatnam, Kakinada and Krishnapatnam. Cyclones form over the Bay of Bengal and affect the coast.
Worked example
Explain why Rayalaseema often receives less southwest monsoon rain than the coastal districts. Reasoning: moist winds from the Arabian Sea first hit the Western Ghats; Rayalaseema lies in the rain-shadow zone. Coastal Andhra faces the Bay of Bengal and receives both southwest and northeast monsoon rain. The northeast monsoon is therefore important for Rayalaseema's tanks and groundwater.
Traps that cost marks
Do not confuse the Godavari with the Krishna; do not treat the Eastern Ghats as a continuous wall; and do not assume black soil is confined to the Deccan. In AP, delta soils, red soils and black soils support different crops.
