Black soil is favourable for the cultivation of
Answer: A
Black soil favours cotton.
Regur, formed from the weathering of Deccan lava, is clayey and retains moisture through long dry spells, which is exactly what a long-duration crop like cotton needs. It is rich in lime, magnesia and potash but poor in nitrogen.

The column of atmosphere is divided into five different layers namely:
Answer: D
The layers are troposphere, stratosphere, mesosphere, ionosphere and exosphere.
Temperature falls through the troposphere, rises through the stratosphere because ozone absorbs ultraviolet, falls again through the mesosphere, and rises steeply in the ionosphere or thermosphere. The lithosphere and pyrosphere are parts of the solid earth, not the atmosphere.

Which of these rivers does not flow into the Bay of Bengal?
Answer: B
Correct answer: The Narmada
The Narmada flows west into the Arabian Sea; the other three flow east into the Bay of Bengal. The reason is structural. The Deccan plateau tilts gently eastward, so almost every peninsular river - the Mahanadi, Godavari, Krishna and Kaveri - rises near the western coast and crosses the entire peninsula to the east, building a large delta at its mouth. The Narmada and the Tapi are the exceptions, and both flow through rift valleys - the Narmada between the Vindhya and Satpura ranges - troughs formed by faulting. They follow a fracture in the crust rather than the regional slope. That also explains a second difference: both form estuaries rather than deltas, because they carry little silt and discharge into a subsiding coast with strong tides. The Narmada is about 1,312 km long, rises at Amarkantak, and carries the Sardar Sarovar dam.

The narrow meandering bands of swift winds which blow in the mid-latitudes near the tropopause and encircle the globe are known as
Answer: A
These are the jet streams.
They are narrow ribbons of wind near the tropopause, 9 to 12 km up, blowing west to east at 100 to 400 km/h. The subtropical jet's seasonal shift north of the Himalayas triggers the burst of the Indian monsoon, and aircraft ride them to save fuel.

Answer: C
Kanyakumari lies north of the Equator.
It is at about 8°4′N, so it is north of the Equator and well south of the Tropic of Cancer, which crosses India at 23°30′N. The Tropic of Capricorn lies in the southern hemisphere and does not touch India at all.
