[Mission 2022] QUIZ – 2022: INSIGHTS STATIC QUIZ, 16 May 2022 – Geography – INSIGHTSIAS

Solution: c)

Shipki La is a mountain pass and border post on the India-China border. The river Sutlej enters India near this pass. The road is an offshoot of the ancient Silk Road.

Solution: a)

• Dendritic pattern:This pattern develops where the river channel follows the slope of the terrain. The stream with its tributaries resembles the branches of a tree, thus the name dendritic.
• Trellis pattern:A river joined by its tributaries, at approximately right angles, develops a trellis pattern. A trellis drainage pattern develops where hard and soft rocks exist parallel to each other.
• Rectangular pattern:A rectangular drainage pattern develops on a strongly jointed rocky terrain.
• Radial pattern: It develops when streams flow in different directions from a central peak or dome-like structure.

Solution: c)

Solution: b)

The North-eastern Plateau:

In fact it is an extension of the main Peninsular plateau. It is believed that due to the force exerted by the north-eastward movement of the Indian plate at the time of the Himalayan origin, a huge fault was created between the Rajmahal hills and the Meghalaya plateau. Later, this depression got filled up by the deposition activity of the numerous rivers.

Today, the Meghalaya and Karbi Anglong plateau stand detached from the main Peninsular Block. The Meghalaya plateau is further sub-divided into three: (i) The Garo Hills; (ii) The Khasi Hills; (iii) The Jaintia Hills. An extension of this is also seen in the Karbi Anglong hills of Assam. Similar to the Chotanagpur plateau, the Meghalaya plateau is also rich in mineral resources like coal, iron ore, sillimanite, limestone and uranium. This area receives maximum rainfall from the south west monsoon. As a result, the Meghalaya plateau has a highly eroded surface. Cherrapunji displays a bare rocky surface devoid of any permanent vegetation cover.

Solution: b)

A characteristic feature of the cold weather season over the northern plains is the inflow of cyclonic disturbances from the west and the northwest. These low-pressure systems, originate over the Mediterranean Sea and western Asia and move into India, along with the westerly flow.

They cause the much-needed winter rains over the plains and snowfall in the mountains. Although the total amount of winter rainfall locally known as ‘mahawat’ is small, they are of immense importance for the cultivation of ‘rabi’ crops.
