Major Physiographic Divisions

The Indian Desert is linked with low rainfall west of the Aravalli. Exam tip: study Aravalli and Thar together.

The Luni is regarded as the largest river of the Indian Desert. It rises in the Aravalli region, flows westwards, and its water becomes saline in the lower course before reaching the Rann of Kachchh. Therefore, it is neither a perennial Himalayan river nor a river of the Ganga Plain. Exam tip: associate the Luni with the Thar Desert and saline water.

Lakshadweep is linked with western sea region and Andaman-Nicobar with eastern sea region. Exam tip: remember island groups with water bodies.

Lakshadweep is linked with coral-nature islands. Exam tip: connect Lakshadweep with Arabian Sea and coral.

Andaman-Nicobar are in Bay of Bengal and Lakshadweep is in Arabian Sea. Exam tip: do not reverse water-body clues.

India's six physiographic divisions show different origins and landforms. Exam tip: remember the whole integrated framework.

In general location, Himalaya comes in north, then plains, then plateau and coastal areas. Exam tip: understand spatial order.

Northern Plains are identified by alluvial deposits and local belts. Exam tip: study formation and local forms together.

The Indian Desert is a sandy arid region, not coral islands. Exam tip: keep desert and island clues separate.

Himadri is a mountain range while Khadar is an alluvial belt of plains. Exam tip: identify name category first.

These clues are linked with the Bhabar belt. Exam tip: connect coarse deposits and Himalayan foothills with Bhabar.

The correct answer is Terai. South of the Bhabar belt in the Himalayan foothills, streams re-emerge at the surface, making the region moist, marshy, and rich in vegetation. Himadri is the northernmost and highest Himalayan range, not a marshy belt south of Bhabar. Exam tip: remember the foothill sequence from north to south as Bhabar followed by Terai.

Bhangar is the higher part linked with old alluvium of Northern Plains. Exam tip: connect Bhangar with old alluvium.

Khadar is the newer alluvial deposit found in the floodplains of rivers. Rivers regularly bring and spread fresh layers of fine sediment during floods, so Khadar is generally renewed more often and is usually more fertile. It is found in the lower areas near active river channels. This idea helps distinguish it from Bhangar, which is older alluvium lying on relatively higher terraces.

The clues are “new alluvium,” “flood plain,” and “Northern Plains.” All three point directly to Khadar, so option A is correct. Bhangar would be the suitable term if the question referred to older alluvium and a higher surface. Himadri is a Himalayan range, and the Eastern Ghats are a hill system, so neither is connected with these alluvial divisions.

The correct fact is that plateau is made of old rocks and plains of alluvial deposits. Exam tip: do not reverse formation bases.

Large deltas form on the eastern coast and western coast is narrow. Exam tip: combine width and delta clues.

Godavari is a major river forming a delta on east coast. Exam tip: study east-flowing rivers and deltas together.

Narmada flows westward into Arabian Sea. Exam tip: treat Narmada-Tapi as west-flowing examples.

Western Coastal Plains are linked with Arabian Sea, not Bay of Bengal. Exam tip: match coast and water body.

This option correctly links direction, formation and example. Exam tip: verify combined clues separately.
