Question : 1
Basaltic lava is found in the
a) Indo-Gangetic Plain
b) Deccan Trap
c) North-Eastern Hills
d) Himalayas
Answer »Answer: (b)
The Deccan Traps are a large igneous province located on the Deccan Plateau of west-central India (between 17°–24°N, 73°–74°E) and one of the largest volcanic features on Earth.
They consist of multiple layers of solidified flood basalt that together are more than 2,000 m (6,562 ft) thick and cover an area of $500000 km^2$ (193,051 sq mi) and a volume of $512000 km^3$ (123,000 cu mi).
The term “trap”, used in geology for such rock formations, is derived from the Swedish word for stairs and refers to the steplike hills forming the landscape of the region.
Question : 2
The Mohorovicic (Moho) Discontinuity separates
a) Sima and Nife
b) Outer core and Mantle
c) Crust and Mantle
d) Inner and Outer core
Answer »Answer: (c)
The Mohorovicic discontinuity usually referred to as the Moho, is the boundary between the Earth’s crust and the mantle. Named after the pioneering Croatian seismologist Andrija Mohorovicic, the Moho separates both the oceanic crust and continental crust from the underlying mantle.
The Moho mostly lies entirely within the lithosphere; only beneath mid-ocean ridges does it define the lithosphere-asthenosphere boundary.
Question : 3
Which one of the following is a Sedimentary Rock?
a) Basalt
b) Granite
c) Arkose
d) Charnockite
Answer »Answer: (c)
Arkose is a detrital sedimentary rock, specifically a type of sandstone containing at least 25% feldspar.
It is commonly coarse-grained and usually either pink or grey (depending on the colour of feldspar).
Question : 4
The topography of the plateau is ideal for
a) mining
b) cultivation
c) generation of hydro power
d) forestry
Answer »Answer: (c)
The prospect of producing electricity from the hydrological resources of the Plateau region lies not, as has been suggested, in the ‘region’s fast-flowing rivers'. The flow rate of most rivers in the region is relatively slow.
However, the sloped topography of the plateau itself provides enormous capacity to generate electricity. All existing and planned hydropower projects in the region are based on the simple engineering principle of utilizing gravity to generate energy from the region’s rivers. The steep escarpments found in the south-eastern portion of the region provide the natural topographical mechanism to subject the region’s water resources to the energy-producing force of gravity.
Question : 5
The Pennines (Europe), the Appalachians (America) and the Aravallis (India) are examples of
a) Block mountains
b) Young mountains
c) Fold mountains
d) Old mountains
Answer »Answer: (d)
Question : 6
Desertification can be checked by
a) contour ploughing
b) plugging gullies
c) forming shelter belts
d) checking over-grazing
Answer »Answer: (d)
Overgrazing is the major cause of desertification worldwide. Plants of semi-arid areas are adapted to being eaten by sparsely scattered, large, grazing mammals which move in response to the patchy rainfall common to these regions.
Early human pastoralists living in semi-arid areas copied this natural system. They moved their small groups of domestic animals in response to food and water availability. Such regular stock movement prevented overgrazing of the fragile plant cover.
