The Peninsular Plateau

The Peninsular Plateau is a stable region made of old hard rocks. Exam tip: link it with the ancient base of India.

Due to the eastward slope, many Peninsular rivers flow east. Exam tip: study slope and river mouths together.

Narmada and Tapi are major west flowing Peninsular rivers. Exam tip: remember them as exceptions to the general eastward flow.

The Deccan Trap is formed from layered lava flows. Exam tip: link Trap with step like lava relief.

East flowing rivers cut the Eastern Ghats at many places. Exam tip: connect discontinuous Ghats with river cutting.

Continuous Western Ghats lift moist winds and cause orographic rain. Exam tip: understand Western Ghats as a monsoon barrier.

A rift valley is related to a fault like structure in the crust. Exam tip: connect Narmada with rift valley and westward flow.

Black soil forms from weathering of basaltic lava in the Deccan Trap. Exam tip: remember origin and soil together.

Old rocky structure is linked with mineral wealth. Exam tip: remember Chotanagpur as a mineral region.

Slope influences the direction of river flow. Exam tip: link Central Highlands with drainage direction.

These plateaus are considered separated north eastern extensions of the Peninsular landmass. Exam tip: remember the north eastern plateau parts.

Rajmahal Hills are considered linked with the eastern plateau extension. Exam tip: link them with Peninsular extension.

The direct answer is A: the Aravalli is a very old mountain range. A mountain range that has been exposed to weathering and erosion for a very long geological period gradually becomes lower, narrower and more broken. The Aravalli Range is among the ancient geological mountain systems of India and is much older than the young, high Himalayas. The reasoning is: strong erosion over immense time removes material; removal reduces height and sharpness; therefore a highly eroded range generally indicates great age, although erosion alone should not be used as the only possible geological evidence. Option A is correct because it gives the conclusion supported by the Aravalli’s worn-down appearance. Option B is wrong because the Himalayas are the young fold mountains, whereas the Aravalli is not a newly formed Himalayan chain. Option C is wrong because sea tides do not build a long inland mountain range of this kind. Option D is wrong because the Aravalli is not part of the Ganga Delta; a delta is a depositional landform made near a river mouth. The memory cue is: “Aravalli is ancient and worn; Himalaya is young and high.”

The direct answer is C, the Narmada. A rift valley is a long, depressed zone formed when the crust is faulted or pulled apart. Rivers flowing through such valleys often follow a relatively straight structural trough. In India, the Narmada flows westward between the Vindhya and Satpura ranges through a rift valley and enters the Arabian Sea. The reasoning is: identify westward flow; identify the rift-valley clue; match both features with the Narmada. Option A, Godavari, is wrong because it generally flows eastward across the Deccan Plateau into the Bay of Bengal and is not the standard rift-valley answer. Option B, Kaveri, also flows generally eastward into the Bay of Bengal and is not associated with this classic rift-valley description. Option C is correct because Narmada is the well-known west-flowing rift-valley river. Option D, Mahanadi, generally flows eastward to the Bay of Bengal and is not the expected river here. The exam cue is: Narmada and Tapi are important west-flowing peninsular rivers; Narmada is especially linked with a rift valley.

East flowing rivers form deltas with more deposition, while Narmada Tapi form estuaries. Exam tip: remember mouth types.

Nilgiri is the meeting area of both Ghats. Exam tip: see it as an important junction of southern plateau structure.

Anai Mudi is a major high peak of the Western Ghats. Exam tip: link it with major heights of South India.

Doda Betta is a major peak of the Nilgiri Hills. Exam tip: remember peak and hill region pairs.

Hard rocks and height differences create waterfalls in plateau rivers. Exam tip: connect waterfalls with relief.

The direct answer is A: Jog Falls is associated with the Sharavathi River. A waterfall forms where river water descends steeply over a resistant rock step, escarpment, or other sharp height difference. Jog Falls is a major waterfall in Karnataka on the Sharavathi River. The reasoning is: identify the named waterfall; recall its river association; match Jog Falls with Sharavathi. Option A is correct because Sharavathi creates the famous Jog Falls, also called Gerosoppa Falls, in the Western Ghats region. Option B, the Ganga, is wrong because Jog Falls is not on the Ganga; the Ganga is a major Himalayan river system of northern India. Option C, the Brahmaputra, is wrong because it is another Himalayan river flowing through the north-east, not the river connected with Jog Falls. Option D, the Jhelum, is wrong because Jhelum is associated with the Kashmir region and does not form Jog Falls. The question tests a factual river-and-waterfall pair, not a general definition of waterfalls. Memory cue: Jog Falls—Sharavathi; keep this pair together for map and matching questions.

The moisture retention capacity of black soil is useful for cotton. Exam tip: remember black soil and cotton together.

The direct answer is A: the name “Ganga of the South” highlights Godavari’s large and important river system in South India. A nickname does not mean that Godavari originates in the Himalayas or is physically the same river as the Ganga. It expresses comparative importance, size and influence within southern India. The reasoning is: Godavari rises in the Peninsular Plateau, flows generally eastward across the Deccan region, receives tributaries, supports agriculture and settlements, and reaches the Bay of Bengal through a delta. These features make it a major river system. Option A is correct because it explains the geographical meaning of the nickname. Option B is wrong because Godavari does not rise in the Himalayas; its source is in the Western Ghats area of Maharashtra. Option C is wrong because Godavari is not the river flowing in the westward rift valley; that description is associated mainly with Narmada and Tapi. Option D is wrong because Godavari reaches the Bay of Bengal and forms a delta, not an estuary in the Arabian Sea. The exam cue is: “Godavari—major east-flowing Peninsular river, Bay of Bengal, South India’s Ganga.”

These rivers flow eastward into the Bay of Bengal. Exam tip: group rivers by their direction of flow.

Peninsular rivers vary seasonally because they are rain fed. Exam tip: distinguish them from Himalayan rivers.

A high western edge and eastward slope make many rivers east flowing. Exam tip: connect height and slope with flow.
