QUIZ – 2020: INSIGHTS STATIC QUIZ, 16 June 2020 – Geography

Solution: c)

Oil palm growers in Andhra Pradesh are facing big trouble as plantations in the northern part of the State, particularly in East and West Godavari districts, have been hit by white fly infestation.

Vast stretches of oil palm plantation in the State have been hit by white fly, which reportedly crossed over from infected coconut groves in the vicinity. The attack left the farmers poorer by 35-40 per cent in yields last year.

Andhra Pradesh accounts for the bulk of oil palm fruit production in India. Of the two lakh hectares under oil palm cultivation in the country, Andhra Pradesh accounts for 1.5 lakh acres.

Whitefly sucks out all the nutrients from the leaves, resulting in yield losses.

“Oil palm doesn’t require much water. It consumes much less water than paddy and sugarcane. But what it requires is timely supply of water,”

While Malaysia and Indonesia, which dominate the world’s oil palm production, grow the crop in rain-fed conditions, India grows it on irrigated land. This disadvantage sees India having to settle for far lesser yields.

“In Malaysia, you see oil palm plantations spread over hundreds of acres. But in India, we are saddled with small holdings, making it difficult to increase the acreage and operationalise the holdings,”

Solution: b)

Submergent Coasts are those that have been flooded by ocean waters because of a relative rise in the elevation of sea level at that location. The rise in sea level can be either the result of an increase in the volume of water in the ocean basins or the result of the land surface sinking, both of which create an apparent rise in the elevation of sea level. Features of a submergent coastline are drowned river valleys or rias and drowned glaciated valleys or fjords.

Estuaries are often the drowned mouths of rivers.

The Western Coastal Plains of the Indian subcontinent are examples of submergent coastline.

Emergent coasts are a result of local tectonic uplift of the land surface or a fall in the elevation of sea level because of a reduction in the water volume of ocean basins. Quite often, emergent coasts have rocky coastlines with cliffs and nearly flat platforms that extend inland where older coastal plains have been tectonically raised and are now elevated above the modern land and water interface.

The emergent coastline may have several specific landforms:

• Raised beach
• Wave cut platform
• Sea cave

Solution: c)

Most of the metallic minerals in India occur in the peninsular plateau region.

The North-Eastern Plateau Region: This belt covers Chhotanagpur (Jharkhand), Odisha Plateau, West Bengal and parts of Chhattisgarh. It has variety of minerals viz. iron ore, coal, manganese, bauxite, mica.

The South-Western Plateau Region: This belt extends over Karnataka, Goa and contiguous Tamil Nadu uplands and Kerala. This belt is rich in ferrous metals and bauxite. It also contains high grade iron ore, manganese and limestone. This belt packs in coal deposits except Neyveli lignite. This belt does not have as diversified mineral deposits as the north-eastern belt. Kerala has deposits of monazite and thorium.

The North-Western Region: This belt extends along Aravali in Rajasthan and part of Gujarat and minerals are associated with Dharwar system of rocks. Copper, zinc have been major minerals. Rajasthan is rich in building stones i.e. sandstone, granite, marble. Gypsum and Fuller’s earth deposits are also extensive. Dolomite and limestone provide raw materials for cement industry.

The Himalayan belt is another mineral belt where copper, lead, zinc, cobalt and tungsten are known to occur.

Solution: d)

The cryosphere is those portions of Earth’s surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground.

Snow has high albedo.
