The Coastal Plains and Islands

Long rivers bring more sediment and deposit it at their mouths. Exam tip: treat the eastern coast as deposition-dominated.

Narmada and Tapi form estuaries on the western coast. Exam tip: keep the difference between delta and estuary clear.

The Eastern Coastal Plain is broad and delta-dominated. Exam tip: identify the eastern coast by alluvial plains and large rivers.

These three names identify divisions of the Western Coastal Plain. Exam tip: remember the order Konkan, Kanara, Malabar.

The direct answer is option B, the stretch from Goa to Mangaluru. The Kanara, or Kannada, Coast is a section of India’s western coastal plain along the Karnataka coast. In the commonly taught north-to-south arrangement, the western coastal plain is divided into the Konkan Coast in the north, the Kanara Coast in the middle, and the Malabar Coast farther south. Option B is correct because Goa to Mangaluru represents the standard location of the Kanara Coast. Option A, Mumbai to Goa, is associated mainly with the Konkan Coast. Option C, Mahanadi to Krishna, describes a broad part of the eastern coastal plain, not the western Kanara section. Option D, Krishna to Cauvery, also refers to the eastern or southeastern coastal region and is not the Kanara Coast. Some geographical boundaries may be described slightly differently in detailed sources, but the textbook exam identification is Goa to Mangaluru. Memory cue: on the west coast, Konkan comes first, Kanara comes next, and Malabar is in the south.

Backwaters are calm water bodies behind coastal barriers. Exam tip: treat Kerala backwaters as a feature of the Malabar Coast.

The eastern coast is generally understood through Northern Circar and Coromandel parts. Exam tip: keep eastern and western coastal names separate.

Deltas like Godavari and Krishna show the alluvial nature of the eastern coast. Exam tip: remember these rivers as evidence of the eastern coast.

The Cauvery Delta is useful for agriculture due to alluvial soil and irrigation. Exam tip: link deltas with paddy farming.

Sundarbans is important for mangrove and deltaic ecology. Exam tip: connect it with both delta and conservation.

Chilika is a famous lagoon lake on the Odisha coast. Exam tip: treat lagoon as a lake partly separated from the sea.

A delta is low and has many distributaries. Exam tip: understand deltas as fertile but flood-prone areas.

Deposition dominates in a delta, while tidal influence is stronger in an estuary. Exam tip: identify the process at the river mouth.

Deep and indented coasts can provide safe places for ships. Exam tip: connect coastal shape with harbours.

Sediment deposition can make navigation channels shallow. Exam tip: remember the need for deep water for ports.

Lakshadweep is coral in origin while Andaman Nicobar has a different geological origin. Exam tip: keep origins of both island groups separate.

Coral reefs can be quickly affected by temperature and pollution. Exam tip: connect coral islands with conservation.

Deltaic plains attract settlement due to agriculture and water availability. Exam tip: link natural resources with population.

Coastal waters and coastline support many economic activities. Exam tip: understand coasts as multi-use resource regions.

Sediment deposition can make navigation channels shallow. Exam tip: remember the link between deposition and port problems.
