The Peninsular Plateau

Peninsular rivers are rain fed, so water volume changes seasonally. Exam tip: distinguish them from Himalayan rivers.

Continuous erosion in hard rocks can make valleys deep. Exam tip: connect plateau rivers with erosion.

The higher western edge and eastward slope make many rivers flow eastward. Exam tip: connect elevation with flow direction.

The Deccan Trap was formed by repeated outpourings of basaltic lava over a large region. Each flow cooled and hardened into a layer. Later flows covered earlier ones, creating a thick, layered volcanic sequence. The different layers may weather and erode at different rates, so their edges can appear as a series of steps or terraces. This is why the landform is called a trap, a term associated with step-like terrain.

Option A is correct because successive lava flows are the basic geological structure behind the steps. Rivers depositing alluvium would produce depositional plains, not the characteristic layered volcanic plateau. Glacial moraines require glacier action, which is not the main origin of the Deccan Trap, and corals cannot explain this extensive basaltic formation. The essential link is repeated lava flows followed by differential erosion.

Soil and rainfall vary across the plateau, so farming also varies. Exam tip: connect agriculture with physical factors.

The old rocky structure of the Peninsular Plateau is linked with mineral resources. Exam tip: connect minerals with geological structure.

The plateau has more unevenness due to height variation and rocky surfaces. Exam tip: understand the relief difference between plateau and plain.

The distance between Western Ghats and Arabian Sea is short and slope is steep. Exam tip: understand river nature through distance and slope.

East flowing rivers cut the Eastern Ghats and reach the Bay of Bengal. Exam tip: understand the relation between Eastern Ghats and deltas.

The direct answer is A: some rivers drain toward the north and north-east. A slope is the direction in which land surface becomes lower. Water generally flows downhill, so the slope of a plateau helps determine river-flow and drainage directions. The reasoning is: the Central Highlands have a general slope toward the north and north-east; surface water follows lower ground; therefore some rivers and streams flow or drain in those directions. Option A is correct because it expresses the actual meaning of the slope without claiming that every river behaves identically. Option B is wrong because not all rivers of this region flow to the Arabian Sea; several rivers drain eastward toward the Bay of Bengal, while rivers such as the Narmada and Tapi flow westward. Option C is wrong because the Central Highlands are elevated land, not an area under the sea. Option D is wrong because a sloping region does have drainage; slope generally helps water move and form channels. The concept is not that a slope forces every river into one exact route, but that relief influences the broad drainage pattern. Memory cue: higher land gives water a direction—water follows the slope.

The Peninsular Plateau is linked with India's ancient landmass. Exam tip: remember it as a very old landform.

Black soil is linked with basaltic rocks of Deccan Trap and is useful for cotton. Exam tip: remember the soil and crop pair.

Peninsular rivers flow through old hard plateaus and do not bring as much silt as Himalayan rivers. Exam tip: understand the effect of river source.

Black soil developed from weathering of basaltic lava in the Deccan region. Exam tip: connect origin with soil.

Direct answer: Option A, plateau rivers are influenced by steeper slopes and hard rocks. Plateau rivers usually cross ancient, resistant rocks and uneven relief. Their courses may be rocky, with rapids, waterfalls, narrow valleys, and relatively fixed channels. Plain rivers generally flow over softer alluvial deposits and often meander and deposit sediment. Option A is the best choice, although “steeper” is a general comparison, not true at every location. Option B is wrong because plateau rivers do flow. Option C is wrong because plain rivers commonly deposit alluvium. Option D is wrong because relief and rock create real physical differences. Cue: rocky plateau, uneven course; soft plain, meanders and deposits.

Western Ghats increase rainfall on windward slopes and create rain shadow inland. Exam tip: remember the Ghats' effect on monsoon.

Deltas receive silt deposited by rivers, creating fertile land. Exam tip: connect deltas with deposition and agriculture.

Long erosion of old rocky surfaces can form rounded hills and shallow valleys. Exam tip: connect ancient plateaus with eroded landforms.

The western and eastern margins of the Deccan Plateau are not identical. Exam tip: compare the structure of both Ghats.

East flowing rivers cut the Eastern Ghats at many places. Exam tip: understand river direction and Ghats' structure together.

Rocky and uneven relief affects route construction. Exam tip: also remember the effect of relief on human use.

These features are rooted in the plateau's old rocks and geological processes. Exam tip: connect different facts with the basic structure.

River flow indicates the slope and structure of the plateau. Exam tip: connect drainage with map and relief.

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

This plateau is made of old igneous and metamorphic rocks. In exams, link it with the ancient stable landmass of India.
