The Coastal Plains and Islands

Northern Circars and Coromandel are main parts of the eastern coast. Exam tip: connect both with the eastern coast.

Lakshadweep is located in the Arabian Sea. Exam tip: remember Lakshadweep west and Andaman Nicobar east.

A river may deposit silt before meeting the sea and form a delta. Exam tip: remember silt and delta together.

The Kaveri meets the Bay of Bengal and forms a delta on the eastern coast. Exam tip: connect Kaveri with the eastern coast.

Wide deltaic plains of the eastern coast are useful for farming. Exam tip: treat deltas as fertile areas.

The Andaman and Nicobar Islands form a long north-south chain. Exam tip: understand their extension from the map.

Lakshadweep is a small-area group of coral islands. Exam tip: remember its small size and coral origin.

To understand coastal regions one must identify seas directions and locations. Exam tip: map-based questions are common.

Large rivers form deltas on the eastern coast near the Bay of Bengal. Exam tip: identify deposition in situation-based questions.

The western coast is narrow and appears more dissected due to the nearby Western Ghats. Exam tip: remember the narrow nature of the western coast.

The Coromandel coast in the southern eastern coast is associated with Tamil Nadu. Exam tip: connect Coromandel with the south-eastern coast.

Direct answer: A, Konkan. India’s western coastal plain is divided into named sections from north to south. The coastal stretch around Mumbai and extending southward to Goa is called the Konkan coast. Step by step: locate Mumbai on the west coast; move south toward Goa; identify this section as Konkan. Option A is correct. Option B, Malabar, refers mainly to the Kerala coastal region farther south, noted for lagoons and backwaters. Option C, Coromandel, is on the southeastern or eastern coast, chiefly along Tamil Nadu. Option D, Northern Circars, is another eastern coastal section, mainly along Andhra Pradesh and nearby areas. Thus the clue is the exact west-coast location, not merely the word ‘coast’. Memory cue: Mumbai–Goa means Konkan; Kerala means Malabar.

The stretch from Goa to Mangaluru is the middle western coast called the Kannad plain. Exam tip: remember the boundaries of the three parts.

The stretch from Mangaluru to Kanniyakumari is the southern western coast called Malabar. Exam tip: connect Malabar with the south-western coast.

Deltas are formed by deposition of material brought by rivers. Exam tip: remember the word deposition for deltas.

Coastal plains are plain areas along the margins of Peninsular India. Exam tip: connect them with the peninsular region.

There is a major difference in width between the two coastal plains. Exam tip: remember western narrow and eastern wide.

The eastern coastal plain is famous for large river deltas. Exam tip: connect delta rivers with the eastern coast.

Direct answer: A, Konkan, Kannad and Malabar. The Western Coastal Plain is commonly divided from north to south into the Konkan Coast, Kannad Coast and Malabar Coast. A lists all three western-coast divisions, so it is correct. B lists Northern Circars and Coromandel, which are divisions of the Eastern Coastal Plain beside the Bay of Bengal. C, Mahanadi delta, is a feature of the eastern coast, not a complete western-coast division. D, Kaveri delta, is also an eastern-coast feature in the Tamil Nadu region. Thus the key is to recognise the group, not just one place. Memory cue: west-coast sequence is Konkan–Kannad–Malabar; east-coast names include Northern Circars–Coromandel.

The correct answer is Lakshadweep. Lakshadweep is a group of small islands in the Arabian Sea, off the southwestern coast of India. Most of these islands are formed from coral deposits and reefs. Coral reefs develop from the hard remains of tiny marine organisms in warm, shallow seas. Thus, the two clues in the question—coral origin and the Arabian Sea—fit Lakshadweep together.

Andaman and Nicobar are in the Bay of Bengal, although they also contain islands formed through different geological processes. Chilika is a lagoon lake in Odisha, not an island group in the Arabian Sea. Reading both clues together is important: “coral islands” identifies the origin, while “Arabian Sea” identifies the location. Therefore, option A follows.

Barren Island in the Andaman region is famous for an active volcano. Exam tip: treat active volcano as a clue for Barren Island.

Chilika Lake, on the Odisha coast, is a brackish-water lagoon. A lagoon is a shallow coastal water body that remains connected to the sea but is partly separated from it by a sandbar or coastal barrier. Therefore, option A is correct. A glacial lake is formed by glacier-related processes, whereas Chilika is a coastal lagoon. Exam tip: remember Chilika as the lagoon on the Odisha coast.

The eastern coast is wide and gently sloping while the western coast is narrow. Exam tip: understand river forms through physical structure.

Lakshadweep lies west in the Arabian Sea and Andaman Nicobar lies east in the Bay of Bengal. Exam tip: direction is very useful.

Access to the sea makes ports possible for trade and transport. Exam tip: connect ports with sea access.
