The Coastal Plains and Islands

Lakshadweep is linked with coral origin and the eastern coast is known for large deltas. Exam tip: remember separate features of islands and coastal plains.

The Western Ghats lie close to the sea, making the coastal strip narrow. Exam tip: link the position of ghats with coastal plain width.

Mahanadi, Godavari, Krishna and Kaveri form large deltas. Exam tip: remember long rivers with sediment deposition.

Narmada and Tapi flow westward and form estuaries. Exam tip: remember the link between western rivers and estuaries.

The Konkan Coast is a northern section of India’s western coastal plain. In the usual school-level geographical division, it extends roughly from the Mumbai area southward to Goa, along the Arabian Sea and west of the Western Ghats. Therefore, option A is correct. The stretch between the Krishna and Kaveri deltas belongs to the southeastern coastal region, the Odisha–Andhra coast is part of the eastern coastal plain, and Lakshadweep consists of islands rather than the mainland Konkan Coast.

To solve the question, locate the Konkan on the western side of the Indian peninsula. The coast north of Goa, especially around Maharashtra and the Mumbai–Goa stretch, is commonly called Konkan. This distinguishes it from Malabar farther south and from the Coromandel coast on the east. The option describing Mumbai to Goa therefore matches both the location and the standard regional name. The supplied answer A is correct.

Kanara coast is considered the middle part of the western coast. Exam tip: remember the order Konkan, Kanara and Malabar.

The Malabar Coast is the southern section of India’s western coastal plain, mainly along Kerala. Its important geographical feature is the chain of lagoons and backwaters, which are water bodies partly separated from the sea by narrow strips of land. Option B describes the Konkan Coast, while C and D refer to features of the eastern coast. Exam tip: remember the link Kerala—backwaters—Malabar Coast.

Distance of the Eastern Ghats and river sediments make the coast broader. Exam tip: link the eastern coast with deltaic plains.

Northern Circar is the northern part of the eastern coast. Exam tip: connect it with the Mahanadi Krishna region.

Option A is the best answer because the Coromandel Coast forms the southeastern coastal plain, broadly extending from the Krishna delta southward along the Tamil Nadu coast toward Kanyakumari. The Rann–Mumbai stretch belongs to the western coast, and Goa–Kochi is associated with the Konkan and Malabar coasts. Lakshadweep is an island group, not the Coromandel Coast.

The deltas of these rivers define the Eastern Coastal Plain. Exam tip: remember the major delta rivers in order.

Sundarbans is one of the large deltaic regions of the world. Exam tip: connect it with the Ganga Brahmaputra delta.

Chilika Lake is a large brackish-water lagoon on the Odisha coast of eastern India. A lagoon is a shallow water body separated from the sea by a sandbar, barrier, or narrow coastal strip, while remaining connected to the sea through one or more openings. Chilika has this coastal setting beside the Bay of Bengal, so it is an important example of a lagoon landform.

Option A correctly identifies Chilika as a lagoon lake of the eastern coast. It is not a glacial lake of the Western Ghats, a coral island of Lakshadweep, or an estuary of the Arabian Sea. An estuary is a different type of coastal water body where river water meets seawater. Therefore, option A is correct.

Backwaters help local economy and transport. Exam tip: treat them as a feature of the Malabar Coast.

Lakshadweep is a group of coral islands. Exam tip: connect it with the Arabian Sea and coral origin.

Their location is important for maritime connectivity and security. Exam tip: link island location with strategic importance.

Barren Island shows volcanic features in the Andaman Nicobar region. Exam tip: remember it as an active volcano.

Indira Point lies in the Nicobar Islands. Exam tip: connect it with the southernmost point of India.

The indented western coast supports some good harbours. Exam tip: connect coastal shape with harbours.

Deltaic plains are low and have many river branches. Exam tip: treat deltas as fertile but flood-prone areas.
