Frequently Asked Questions
What is the difference between the Peninsular Plateau and the Himalayan mountains in terms of age and structure?
The Peninsular Plateau is an ancient, stable landmass made of hard crystalline rocks, whereas the Himalayas are young, unstable fold mountains formed by ongoing tectonic activity.
Why are the Eastern Ghats discontinuous compared to the Western Ghats?
The Eastern Ghats have been eroded and cut across by several major east-flowing peninsular rivers like the Godavari, Krishna, and Mahanadi, making them much more discontinuous than the unbroken Western Ghats.
How does the physiography of Andhra Pradesh influence its climate and agriculture?
Andhra Pradesh features the Deccan Plateau, the Eastern Ghats, and fertile coastal plains along the Bay of Bengal, which support diverse agricultural patterns ranging from deltaic paddy farming to dryland crops.
