Physical Features of India

Correct answer: A. They kept cutting their pre uplift courses

Antecedent rivers continue cutting their old courses even after mountain uplift. For exams remember deep gorges of Indus and Brahmaputra.

Correct answer: B. It is geologically active and landslide prone

Young fold mountains have steep slopes and higher geological activity. For exams link the Himalayas with earthquakes and landslides.

Correct answer: C. They feed perennial rivers that deposit sediments in plains

Glaciers of Himadri feed rivers and those rivers bring alluvial deposits to plains. For exams remember the Himalaya river plain link.

Correct answer: D. Slope erosion and landslides

Shiwalik is an outer Himalayan range made of loose deposits so erosion may be high. For exams link Shiwalik with unstable slopes.

Correct answer: A. Because they lie between mountain ranges

Dun valleys are sedimentary valleys formed between Shiwalik and Lesser Himalaya. For exams remember Dehradun as an example.

Correct answer: B. Water sinks in Bhabar and returns near surface in Terai

Bhabar is a porous pebbly belt and in Terai water is near the surface. For exams remember the Bhabar Terai sequence.

Correct answer: A. High water table and high moisture

In Terai the water table remains near the surface causing moisture and marshes. For exams remember Terai as a moist foothill belt.

Correct answer: C. Gentle slope and slow flow

In flat plains river speed decreases and winding courses form. For exams link meanders with plains.

Correct answer: D. Development of older alluvial deposits

Bhangar is linked with older alluvial areas where kankar deposits may occur. For exams remember Bhangar old Khadar new.

Correct answer: A. New alluvium is deposited during river floods

Khadar is the new flood belt of rivers where fresh alluvium arrives. For exams remember Khadar as more fertile.

Correct answer: B. Alluvial land between two rivers

The direct answer is B, alluvial land between two rivers. “Doab” comes from two words meaning two and water bodies or rivers. In physical geography, it is the land lying between two rivers, usually formed largely from river-deposited alluvium. Step by step: identify two rivers; locate the area between their channels; recognize its alluvial, often fertile deposits; this is a doab. A, a pass between two mountains, is a mountain pass, not a doab. B is correct. C, an island between two seas, is a different coastal landform. D, salt between two deserts, has no accepted physical meaning for doab. The Ganga–Yamuna Doab is the standard example. Memory cue: doab = do (two) + ab (water).

Correct answer: C. Heavy silt deposition and channel shifting

Brahmaputra brings heavy silt and can shift channels which forms river islands. For exams remember Majuli.

Correct answer: D. Due to heavy silt deposition at the mouth

Silt deposition at the mouth divides the river into many distributaries. For exams link delta with deposition.

Correct answer: A. In tidal saline marshy water

Sundarbans is a mangrove area developed in a tidal saline delta. For exams remember tide salinity and mangroves.

Correct answer: B. It is made of ancient hard igneous and metamorphic rocks

The Peninsular Plateau is a stable landmass made of old hard rocks. For exams remember it as older than the Himalayas.

Correct answer: D. Rift valley system of central India

Narmada Valley between Vindhya and Satpura shows a rift valley route. For exams see this order on a map.

Correct answer: A. Many large rivers flow toward Bay of Bengal

Due to Deccan's eastward slope rivers like Godavari Krishna and Kaveri flow east. For exams study slope and river direction together.

Correct answer: B. From layered basaltic lava flows

Deccan Trap is step like land made from layers of basaltic lava. For exams link the word trap with step like form.

Correct answer: C. Shrink and swell capacity

Black soil swells with moisture and shrinks on drying. For exams remember black soil Deccan and cotton link.

Correct answer: D. Ancient hard plateau rocks

Chotanagpur is an ancient rocky plateau and famous for mineral resources. For exams remember coal and iron ore.

Correct answer: A. Ganga Brahmaputra Plain

Meghalaya Plateau is a northeastern extension of Peninsular Plateau but appears separated by plains. For exams remember Garo Khasi Jaintia.

Correct answer: B. It is a very ancient and eroded range

Aravalli is an ancient mountain range eroded over a long time. For exams remember Aravalli as older than Himalaya.

Correct answer: C. Moist winds hit the Ghats rise upward then rainfall occurs

Moist winds of the Arabian Sea branch hit Western Ghats and cause rainfall. For exams remember windward slope.

Correct answer: D. Mahanadi Godavari Krishna Kaveri

East flowing peninsular rivers cut the Eastern Ghats and reach Bay of Bengal. For exams remember Eastern Ghats as fragmented.

Correct answer: A. Junction of Western and Eastern Ghats

Nilgiri is linked with the contact zone of Western and Eastern Ghats in South India. For exams see the southern mountain map.
