Physical Features of India

Himalayan rivers receive water from glaciers and rain so they are more perennial. For exams remember the difference in sources.

Western Ghats block moist winds and the leeward side receives less rainfall. For exams remember windward and leeward terms.

Coastal plains are useful for ports due to sea contact and flat land. For exams remember coast and trade relation.

Eastern coast has large river deltas and western coast is narrow due to Western Ghats. For exams remember this comparison.

Bhabar is a pebbly porous foothill belt of the Himalayas not a marine marsh. For exams keep Bhabar and Rann of Kachchh separate.

Himalayas are young fold mountains and the Peninsular Plateau is an ancient stable block. For exams remember comparison of geological age.

Bhabar is a pebbly and gravelly porous belt in the Himalayan foothills. For exams keep it separate from Terai.

Narmada flows westward through a rift valley into the Arabian Sea. For exams remember Narmada and Tapi as special west flowing rivers.

Godavari and Krishna are east flowing rivers that form deltas on the eastern coast. For exams remember Bay of Bengal.

Sundarbans is the tidal saline mangrove region of the Ganga Brahmaputra Delta. For exams identify this clue quickly.

Antecedent rivers keep cutting their old course even after mountain building. For exams remember deep gorges of Indus and Brahmaputra.

Young fold mountains are geologically more active. For exams link the Himalayas with seismic zones.

Glaciers of Himadri feed many rivers. For exams remember the glacier and perennial river link.

The loose sedimentary structure of Shiwalik can make slopes unstable. For exams remember Shiwalik as Outer Himalaya.

Dun valleys occur between Shiwalik and Lesser Himalaya. For exams keep Dehradun as an example.

Bhabar is porous while water is near the surface in Terai. For exams remember the Bhabar Terai sequence.

Near surface water and high moisture in Terai support vegetation. For exams remember Terai as a moist foothill belt.

In flat plains river velocity decreases and deposition increases. For exams link river landforms with plains.

Bhangar is older alluvium deposited earlier by rivers and is generally found on relatively higher parts of the floodplain. Khadar is newer alluvium deposited repeatedly in the lower floodplain near rivers and is considered more fertile. Option A reverses these features. Exam tip: remember Bhangar as ‘old-higher’ and Khadar as ‘new-lower’.

A doab is fertile alluvial land between two rivers. For exams take Ganga Yamuna Doab as an example.
