The Peninsular Plateau

Plateau rivers form waterfalls due to hard rocks and height differences. Exam tip: connect waterfalls with plateau rivers.

Moist winds of the Arabian Sea branch strike the Western Ghats and cause rainfall. Exam tip: link this with orographic rainfall.

Western Ghats lift moist winds and increase rainfall on the windward slope. Exam tip: understand windward and rain shadow.

Peninsular rivers mainly get water from monsoon rainfall. Exam tip: remember the difference between rain fed and glacier fed rivers.

The direct answer is A: the Godavari, Krishna and Kaveri flow generally eastward and enter the Bay of Bengal. They are important Peninsular rivers, not Himalayan rivers. The basic reasoning is simple: their courses move across the Deccan region towards the eastern coast, and their lower ends, or mouths, reach the Bay of Bengal. Option A is correct because it states this shared direction and destination. Option B is wrong because these three are not the main west-flowing rivers entering the Arabian Sea. Option C is wrong because they rise in the Peninsular region and are not Himalayan rivers. Option D is wrong because sea currents are moving seawater, while these are rivers carrying freshwater over land. Exam cue: Godavari, Krishna and Kaveri are commonly remembered as east-flowing Peninsular rivers.

The direct answer is A: the Mahanadi drains towards the eastern coast and enters the Bay of Bengal. A river’s drainage direction means the direction in which its water flows and finally reaches a sea or ocean. The Mahanadi flows across eastern India and forms a delta before meeting the Bay of Bengal. Option A is correct because the river reaches the east coast. Option B is wrong because the Mahanadi is not a west-flowing river entering the Arabian Sea. Option C is wrong because the Northern Himalaya is a mountain region, not the coast or final sea into which this river drains. Option D is wrong because the Thar Desert is an inland desert and is not the Mahanadi’s outlet. Memory cue: Mahanadi is one of the important east-flowing Peninsular rivers.

East flowing rivers deposit sediments near the Bay of Bengal and form deltas. Exam tip: connect delta with river deposition.

These plateaus are geologically considered linked with the Peninsular Plateau. Exam tip: note the north eastern extension.

Rajmahal Hills are studied in the context of the eastern extension of the Peninsular Plateau. Exam tip: remember their north eastern plateau link.

The Aravalli Range is one of India’s oldest fold mountain systems. Long-term erosion has made its peaks relatively low and worn down. The Himalayas are young fold mountains, so option B is incorrect. Exam tip: remember the Aravallis as ancient, highly eroded fold mountains.

Long term erosion on old rocky surfaces forms such landforms. Exam tip: connect old plateaus with eroded landforms.

Old hard rock structures are associated with mineral resources. Exam tip: connect minerals with rock structure.

Direct answer: Option A, the Western Ghats form the high western edge of the Deccan Plateau. The Deccan Plateau lies south of the Narmada and is bordered on its western side by the Western Ghats, also called Sahyadri. These hills are generally higher and more continuous than the Eastern Ghats, so they form the plateau’s elevated western margin. Option B is wrong because the Western Ghats are not in the Ganga Plain. Option C is wrong because they are not the Himalayas’ highest range. Option D is wrong because a mountain range is not merely a river delta. Map cue: Deccan inside, Western Ghats along its west.

Eastern Ghats are generally lower and more broken than Western Ghats. Exam tip: remember both height and continuity.

Many east flowing Peninsular rivers form deltas in the Bay of Bengal. Exam tip: remember direction and mouth together.

West flowing Narmada and Tapi form estuaries due to relatively less deposition. Exam tip: distinguish them from delta forming eastern rivers.

Western Ghats act as a continuous barrier affecting monsoon and routes. Exam tip: study the effects of relief too.

River erosion on hard rocks creates valleys and waterfalls. Exam tip: understand the relation between rock and river landforms.

Both Ghats clearly mark the western and eastern edges of the Deccan Plateau. Exam tip: identify the Ghats on the map.

Peninsular rivers depend more on monsoon rainfall. Exam tip: understand the relation between river source and flood timing.

Soil and rainfall vary across the plateau. Exam tip: connect agriculture with physical factors.

Direct answer: Option A, drainage explains slope, river direction, and landforms. Drainage means the network and movement of rivers and streams. On a plateau, the direction in which rivers flow helps us identify the general slope. River courses also show valleys, resistant rocks, faults, and the way the surface has been shaped by erosion. Thus drainage is closely connected with relief and structure. Option B is wrong because population belongs to human geography. Option C is wrong because language regions do not explain physical landforms. Option D is wrong because drainage cannot remove or end a sea boundary. Cue: read rivers as clues to relief.

The Peninsular Plateau is identified by old rocks, minerals and plateau relief. Exam tip: remember all three features together.

In Deccan lava regions, weathering of basalt forms black soil. Exam tip: remember lava, basalt and black soil together.

The Peninsular Plateau is among the oldest landmasses of India and its rocks are hard. In exams, link it with ancient crystalline rocks.
