The Coastal Plains and Islands

Correct answer: D. Northern young fold mountains

The correct answer is D, northern young fold mountains. Coastal Plains are relatively narrow, low-lying strips of land along a coast. India has a Western Coastal Plain beside the Arabian Sea and an Eastern Coastal Plain beside the Bay of Bengal, so A, B, and C are useful identification clues. D points to the Himalayas, which are young fold mountains located along northern India. They are a mountain system, not a coastal plain. A correctly describes the low and level land beside the sea. B reminds us that India has eastern and western coastal sections. C identifies the two water bodies bordering those plains. Common confusion: “coastal” describes a position beside the sea, whereas “northern young fold mountains” describes the Himalayan relief and location.

Correct answer: A. Western Coastal Plain — Bay of Bengal

The correct answer is A. The Western Coastal Plain lies beside the Arabian Sea, not the Bay of Bengal, so this option reverses the correct water-body match. The Eastern Coastal Plain lies beside the Bay of Bengal, making B correct. Lakshadweep is an island group in the Arabian Sea, so C is correctly matched. The Andaman and Nicobar Islands are in the Bay of Bengal, so D is also correct. To solve the question, first divide India’s coast into west and east: west corresponds to the Arabian Sea, and east corresponds to the Bay of Bengal. Then check the island groups separately. Memory cue: west = Arabian Sea; east = Bay of Bengal. Do not confuse Lakshadweep with Andaman and Nicobar.

Correct answer: A. Because the Western Ghats run close and parallel to the sea

The Western Ghats run close to the Arabian Sea so the plain is narrow. Exam tip: link mountain position with plain width.

Correct answer: A. Because the Eastern Ghats are comparatively farther from the coast

The Eastern Ghats lie away from the coast giving the plain more space. Exam tip: remember the position of the ghats.

Correct answer: A. Mumbai and Goa

Konkan is the northern part of the western coast from Mumbai to Goa. Exam tip: learn the three western coast divisions in order.

Correct answer: A. The middle part from Goa to Mangaluru

The direct answer is A: the Kannad plain is the middle part of the western coastal plain, extending broadly from Goa to Mangaluru. India’s western coastal plain is commonly divided from north to south into the Konkan coast, the Kannad or Kanara plain, and the Malabar coast. The reasoning is: first locate the western coastal plain between the Western Ghats and the Arabian Sea; then remember the north-to-south order; Konkan lies in the north, Kannad lies in the middle, and Malabar lies farther south. Option A is correct because Goa to Mangaluru identifies the central Kannada/Kanara coastal section in the school-level division. Option B is wrong because Mumbai to Goa represents the northern Konkan section, not Kannad. Option C is wrong because Mangaluru to Kanniyakumari represents the southern Malabar section. Option D is wrong because the Ganga Delta belongs to the eastern coastal region around the Ganga–Brahmaputra system, not to the western coastal plain. The memory cue is the north-to-south sequence: “Konkan, Kannad, Malabar.”

Correct answer: A. Southern western coast from Mangaluru to Kanniyakumari

Direct answer: A, the southern western coast from Mangaluru to Kanniyakumari. The western coastal plain lies between the Western Ghats and the Arabian Sea. Its southern section is called the Malabar Coast and includes much of Kerala, extending broadly from the Mangaluru area toward Kanniyakumari. A is correct. B, Mumbai to Goa, describes the Konkan section, not Malabar. C is wrong because the Ganga plain is an inland northern plain, not a coastal division. D is wrong because the Terai is a foothill belt along the Himalayas. Option A also fits the important Kerala association, but the coastal-range description is the main reason. Memory cue: western coast from north to south—Konkan, Kannad, Malabar.

Correct answer: A. Eastern coastal plain

Northern Circars are the northern part of the eastern coastal plain. Exam tip: learn eastern coast divisions from north to south.

Correct answer: A. On the south-eastern coast

The Coromandel Coast is located along the south-eastern side of India. It forms the southern part of India’s eastern coastal plain and faces the Bay of Bengal. The coast mainly extends along the shoreline of Tamil Nadu and nearby parts of the southeastern coast. Its location is associated with important rivers, deltas, and seasonal rainfall from the northeast monsoon.

The south-eastern coast is the only option that identifies the correct region. The north-western coast faces the Arabian Sea and is not the Coromandel Coast. The Himalayas and the Thar Desert are inland physical regions with entirely different locations. Therefore, option A is correct. Remembering its connection with the Bay of Bengal helps distinguish it from the western coastal plains.

Correct answer: A. Large east-flowing rivers deposit more silt

Large rivers deposit silt on the gentle eastern coast forming deltas. Exam tip: connect deltas with deposition.

Correct answer: A. Eastern coastal plain

The Mahanadi meets the Bay of Bengal and forms a delta on the eastern coast. Exam tip: link Mahanadi with Odisha and the eastern coast.

Correct answer: A. Eastern coast

These rivers fall into the Bay of Bengal and form deltas on the eastern coast. Exam tip: remember the eastern coast as a delta coast.

Correct answer: A. Eastern coast of Odisha

Chilika Lake is a famous lagoon on the Odisha coast. Exam tip: connect it with the eastern coastal plain.

Correct answer: A. Arabian Sea

Lakshadweep lies in the Arabian Sea to the south-west of India. Exam tip: treat Lakshadweep as the western sea island group.

Correct answer: A. Bay of Bengal

Andaman and Nicobar lie in the Bay of Bengal to the south-east of India. Exam tip: remember them as the eastern island group.

Correct answer: A. Coral deposits

Answer: A, coral deposits. Lakshadweep is a group of coral islands in the Arabian Sea. Coral organisms build hard calcareous structures in warm, shallow marine waters, and the accumulation of these materials can form reefs and coral islands over long periods. B is wrong because glacial deposits are produced by moving or melting ice and are not the characteristic origin of Lakshadweep. C is wrong because river alluvium is deposited by rivers, whereas Lakshadweep is an island group in the sea. D is wrong because desert sand is a land-based aeolian deposit, not the main origin of these islands. Memory cue: Lakshadweep is famous for coral islands; the Maldives are another well-known coral-island example.

Correct answer: A. Lakshadweep

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

Correct answer: A. Andaman and Nicobar Islands

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

Correct answer: A. Andaman and Nicobar Islands

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

Correct answer: A. Delta formation by rivers

On a level gentle slope rivers deposit silt and form deltas. Exam tip: connect level coasts with deposition.

Correct answer: A. Because the slope is steep and the coastal plain is narrow

Steep slope and narrow plains reduce the formation of large deltas. Exam tip: remember the western coast as a narrow coast.

Correct answer: A. Due to ports fishing and trade

Coastal plains are important for ports trade fishing and settlement. Exam tip: connect coasts with marine economy.

Correct answer: A. Western coastal plain

Direct answer: A, Western Coastal Plain. India’s coastal plain beside the Arabian Sea is called the Western Coastal Plain. It lies between the Arabian Sea on the west and the Western Ghats on the east. A is correct because it directly names this physical region. B, Eastern Coastal Plain, lies beside the Bay of Bengal, not the Arabian Sea. C, Ganga Plain, is a large inland alluvial plain in northern India. D, Deccan Plateau, is an elevated interior region south of the Narmada and is not a narrow sea-margin plain. The adjoining sea is the quickest clue: Arabian Sea means western coast, while Bay of Bengal means eastern coast. Memory cue: west equals Arabian Sea; east equals Bay of Bengal.

Correct answer: A. Eastern coastal plain

The eastern coastal plain extends along the Bay of Bengal. Exam tip: remember Bay of Bengal with the eastern coast.

Correct answer: A. Western coastal plain

All three are subdivisions of the western coastal plain. Exam tip: remember their order from north to south.
