The Coastal Plains and Islands

Lagoons are partly separated brackish water areas near the coast. Exam tip: connect lagoons with coastal water and backwaters.

On the eastern coast, large rivers deposit sediments on a gentle slope and form big deltas. Exam tip: connect deltas with river deposition.

The nearby Western Ghats make the plain narrow and the slope steep. Exam tip: remember narrow coast and fewer deltas together.

Deltas contain alluvial soil deposited by rivers. Exam tip: treat deltas as fertile depositional areas.

Lakshadweep is a group of small coral islands in the Arabian Sea. Exam tip: use coral and Arabian Sea as clues.

Their location near sea routes gives them strategic importance. Exam tip: connect island location with importance.

The Coromandel Coast is linked with the southern part of the eastern coastal plain. Exam tip: associate it with the Tamil Nadu region.

The direct answer is B: Konkan, Kannad, Malabar, from north to south. The western coastal plain lies beside the Arabian Sea and is divided into named sections. Konkan is the northern section, mainly along Maharashtra and Goa; Kannad, also called Karnataka Coast, lies farther south; Malabar lies still farther south, mainly along Kerala. Therefore the sequence moves correctly downward on the map: Konkan → Kannad → Malabar. Option A reverses this order and starts with the southern Malabar. Option B is correct because all three names are western-coast divisions and their north-to-south order is right. Option C names eastern-coast divisions such as Coromandel and Northern Circars, so it is not a western-coast sequence. Option D begins with Kannad and places the northern Konkan last, so it is wrong. Memory cue: “K-K-M” means Konkan, Kannad, Malabar, moving north to south.

The direct answer is C: the landform is a delta. A delta forms where a river reaches a sea or lake, loses speed, and deposits sediment such as silt, sand, and clay. Step by step: the river carries sediment downstream; at the mouth, the water becomes slower and spreads into the receiving water body; the sediment settles; repeated deposition builds low land; the river divides into distributaries that flow around the deposits. A wide, silty mouth divided into distributaries is therefore a strong sign of a delta. Option A, a waterfall, is a steep drop in a river channel, not a sediment-built branching mouth. Option B, a glacier, is a mass of moving ice, not a river-mouth landform. Option C is correct because it matches both deposition and distributaries. Option D, a pass, is a route or low gap through mountains and is unrelated to a river mouth. Exam cue: river mouth plus deposited silt and distributaries usually means delta.

Northern Circars form the northern part of the eastern coastal plain. Exam tip: connect Northern Circars and Coromandel with the eastern coast.

Chilika is a famous lagoon on the eastern coast of Odisha. Exam tip: connect Chilika with Odisha and lagoon.

The Kaveri flows eastward and forms a delta near the Bay of Bengal. Exam tip: link Kaveri with the eastern coast.

The Mahanadi forms a delta on the eastern coast in the Odisha region. Exam tip: associate Mahanadi with the northern eastern coast.

Barren Island in the Andaman region is famous for an active volcano. Exam tip: connect active volcano with Barren Island.

The western coast is narrow because the Western Ghats are close to the sea. Exam tip: compare it with the eastern coast.

Long rivers deposit silt on a gentle slope and form large deltas. Exam tip: check both river length and slope.

Northern Circars and Coromandel are major parts of the eastern coast. Exam tip: keep them separate from western coast divisions.

Indira Point is India's southern point in the Nicobar Islands. Exam tip: connect it with India's southern limit.

Godavari and Krishna enter the Bay of Bengal and form deltas on the eastern coast. Exam tip: include them among delta-forming rivers.

Kavaratti is the administrative centre of Lakshadweep. Exam tip: remember Kavaratti and Lakshadweep as a pair.

The direct answer is C: Lakshadweep. Begin by matching each clue. “Small area” fits a group of small islands. “Coral origin” means the islands were formed mainly from coral deposits and reefs. “Arabian Sea” places the group off India’s south-western coast. Together these three clues identify Lakshadweep. Option A, Andaman Islands, lies in the Bay of Bengal and is not the expected answer for the Arabian Sea clue. Option B, Nicobar Islands, also lies in the Bay of Bengal and is part of the Andaman and Nicobar group. Option C is correct because Lakshadweep is a small coral-island group in the Arabian Sea. Option D, Sundarban, is a delta and mangrove region around the Ganga-Brahmaputra delta, not a coral island group. Exam reasoning should use all clues together rather than noticing only the word “island.” Memory cue: Arabian Sea + coral islands = Lakshadweep.

Sea contact makes ports possible for trade and transport. Exam tip: connect ports with maritime access.

India’s western coastal plain lies between the Western Ghats and the Arabian Sea. It includes coastal stretches such as the Konkan, Kannad, and Malabar coasts. The eastern coastal plain, in contrast, lies beside the Bay of Bengal. Therefore, option A correctly pairs the Arabian Sea with the western coastal plain. Option B reverses the coast, option C places the Bay of Bengal beside the wrong plain, and option D names a sea that is not beside India’s coastal plains.

To answer, identify the sea on each side of the peninsula. The Arabian Sea is west of mainland India, so the plain along that side is called the western coastal plain. The Bay of Bengal is east of India and borders the eastern coastal plain. This simple west–west and east–east matching leads to option A. The supplied answer and explanation accurately describe the geographical relationship.

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

Andaman and Nicobar are considered a mountainous and volcanic chain in the sea. Exam tip: distinguish them from coral Lakshadweep.
