The Peninsular Rivers

Correct answer: B. The general slope of the peninsular plateau is eastward

The slope of the peninsular plateau carries many rivers toward the Bay of Bengal. Exam tip: connect river direction with slope.

Correct answer: C. They flow westward through rift valleys

Narmada and Tapi are west-flowing rivers running through rift valleys. Exam tip: remember both direction and valley together.

Correct answer: A. Deposition of river sediment at the mouth

A delta forms by deposition of sediment brought by a river. Exam tip: link delta with deposition.

Correct answer: D. Because their course is short and slope is relatively steep

A short and steeper course gives less chance for large delta formation. Exam tip: connect Narmada and Tapi with estuaries.

Correct answer: A. It is a large and major river system of South India

Godavari is the longest peninsular river and has a large basin. Exam tip: link Dakshin Ganga with Godavari.

Correct answer: B. Their water mainly depends on monsoon rainfall

Peninsular rivers are rain-fed so their flow changes with seasons. Exam tip: connect seasonal flow with monsoon.

Correct answer: C. Western Ghats

Krishna rises in the Western Ghats and flows eastward. Exam tip: remember both source and flow direction.

Correct answer: A. It plays an important role in irrigation and water supply

Kaveri is an important water source for agricultural areas of South India. Exam tip: connect river use with region.

Correct answer: C. Mahanadi flows eastward and deposits sediment in the Bay of Bengal

The direct answer is C: Mahanadi flows eastward and deposits sediment in the Bay of Bengal. A delta forms near a river’s mouth when the river slows down and leaves behind sediment such as sand, silt and clay. The Mahanadi flows across central and eastern India toward the east coast, enters the Bay of Bengal and builds a delta along the Odisha coast. Option C is correct because it gives both the direction and the process that explain the delta. Option A is wrong because the Mahanadi does not flow westward into the Arabian Sea. Option B is wrong because it does not rise in Tibet or flow through Assam; those details are associated with Himalayan river systems, not the Mahanadi. Option D is wrong because the Mahanadi is not a northern tributary of the Ganga; it is an important east-flowing Peninsular river. The chain is: eastward flow, lower speed near the coast, sediment deposition, delta formation, Odisha coast. Memory cue: Mahanadi means Odisha, east coast, Bay of Bengal and delta.

Correct answer: A. They flow through old hard plateau terrain

River courses change less in old stable terrain. Exam tip: link peninsular rivers with old plateaus.

Correct answer: B. It is a west-flowing peninsular river

The direct answer is B: Narmada is a west-flowing peninsular river. The reasoning has two parts. First, Amarkantak is the source region from which the Narmada rises. Second, the river travels west across central India and reaches the Arabian Sea. It is therefore classified as a west-flowing river of the Peninsular drainage system. A is wrong because an east-flowing river does not match Narmada's direction, even though some peninsular rivers form deltas. C is wrong because Narmada is not a tributary of the Brahmaputra; the Brahmaputra belongs to the northern drainage system. D is wrong because the Bay of Bengal lies to the east, whereas Narmada drains westward into the Arabian Sea. The source and outlet together make B certain. Memory cue: Narmada—Amarkantak to Arabian Sea, westward.

Correct answer: C. Both are west-flowing peninsular rivers

Tapi and Narmada both flow westward into the Arabian Sea. Exam tip: remember their direction pair.

Correct answer: A. East-flowing peninsular river

Godavari rises near the Western Ghats and moves toward the Bay of Bengal. Exam tip: identify a river by source and mouth.

Correct answer: A. It is a South Indian river linked with the Western Ghats region

Kaveri is a major east-flowing river of South India. Exam tip: remember Brahmagiri with Kaveri.

Correct answer: A. They travel a longer distance from the Western Ghats to the eastern coast

Because Western Ghats are near the west coast, east-flowing rivers get a longer course. Exam tip: link distance with source and coast.

Correct answer: B. They divide river water into drainages flowing in different directions

A water divide decides into which river system water will flow. Exam tip: connect Western Ghats with drainage direction.

Correct answer: C. Hard rocky surface and sudden change in slope

A waterfall forms where a river suddenly descends from a higher level to a lower level. In many parts of the Peninsular Plateau, layers of hard rock resist erosion while softer rock is worn away more quickly. Differences in rock resistance, together with a sudden break or steep change in the river’s slope, create a vertical drop. Continued erosion can make the drop more distinct over time.

Option C is correct because it identifies both important topographical conditions: a resistant rocky surface and an abrupt change in gradient. High sea waves do not normally create waterfalls in an inland river channel. Permanent glaciers are not the general cause of waterfalls in Peninsular India, and desert-sand deposition usually produces gentle landforms rather than a sharp drop. The supplied answer C is accurate.

Correct answer: B. It is a famous waterfall associated with the Kaveri River

Shivanasamudra is a major waterfall on the Kaveri River. Exam tip: remember the correct waterfall-river pair.

Correct answer: A. It is a major tributary of Godavari

Pranhita enlarges the drainage area of Godavari. Exam tip: link each tributary with the correct main river.

Correct answer: A. It is a major tributary of Krishna

Tungabhadra adds water and drainage area to the Krishna system. Exam tip: identify Krishna's tributaries separately.

Correct answer: B. Kaveri river system

The direct answer is B: the Kaveri river system. Kabini is a major tributary of the Kaveri. A river system means the main river together with its tributaries and drainage area. Kabini rises in the Western Ghats, flows through Karnataka, and joins the Kaveri at Tirumakudalu Narasipura in Karnataka. Therefore, when studying Kabini, connect it with the Kaveri basin and southern India. Option A, the Indus system, is incorrect because the Indus and its tributaries belong mainly to north-western India and Pakistan; Kabini does not join the Indus. Option B is correct because Kabini joins the Kaveri and contributes water to its river system. Option C, the Brahmaputra system, is incorrect because the Brahmaputra is a separate river of north-eastern India and Tibet. Option D, the Narmada system, is incorrect because Narmada is a west-flowing peninsular river and Kabini is not its tributary. Memory cue: Kabini and Kaveri are both linked with Karnataka and southern India.

Correct answer: A. They flow westward toward the Arabian Sea region

Mahi and Sabarmati are west-flowing rivers of western India. Exam tip: remember smaller west-flowing rivers separately.

Correct answer: A. It generally does not reach the sea through a clear flow

Luni is linked with inland drainage in the dry region of Rajasthan. Exam tip: connect Luni with arid regions.

Correct answer: B. They developed for a long time in old and stable plateau terrain

River valleys mature over time on old stable plateaus. Exam tip: connect geological age with valley form.

Correct answer: C. Identifying their direction and final outlet

Direction and mouth are the simplest bases of river classification. Exam tip: trace source to mouth on a map.
