17 July Static Quiz 2021 (Geography)

Solution: D
Justification: Parts of Saurashtra are prone to drought, and irrigation water is also a politically sensitive issue in this region. SAUNI stands for Saurashtra Narmada Avtaran Irrigation, a project launched in 2012. SAUNI envisages filling several major dams of the arid Saurashtra region by diverting floodwaters overflowing from the Sardar Sarovar Dam across the Narmada in south Gujarat. Unlike traditional irrigation projects, SAUNI is technically a ‘linking’ project, where the water will be filled in irrigation dams that are already equipped with canal network. This network of canals will then help channel water into farms. Also, SAUNI project involves making pipe canals instead of the conventional open canals. The pipelines in the SAUNI project are underground, which means that no land needs to be acquired.

Solution: C
Justification: This is the rough irrigation map of India.

You can clearly note that central India lacks good irrigation facilities. Not all regions in India have high levels of irrigation. Apart from the riverine plains, coastal regions in our country are well-irrigated. The eastern and northern belt have good canal irrigation facilities. In contrast, plateau regions such as the Deccan plateau have low levels of irrigation. Of the total cultivated area in the country a little less than 40 per cent is irrigated even today. In these areas, farming is largely dependent on rainfall.

Solution: A
Justification: Statement 1: Kazakhstan and Turkmenistan have abundant oil and natural gas reserves and Uzbekistan’s own reserves make it more or less self-sufficient.
Statement 2: Kyrgyzstan, Tajikistan and Uzbekistan all have gold reserves and Kazakhstan has the world’s largest uranium reserves.
Statement 3: Fluctuating global demand for cotton, aluminium and other metals (except gold) in recent years has hit Tajikistan hardest, since aluminium and raw cotton are its chief exports − the Tajik Aluminium Company is the country’s primary industrial asset. In fact in 2014, it announced the government’s intention to reduce the acreage of land cultivated by cotton to make way for other crops. Uzbekistan and Turkmenistan are major cotton exporters themselves,

Solution: D
Justification: Kerala State is endowed with a number of occurrences/deposits of minerals such as Heavy Mineral Sands ( Ilmenite, Rutile, Zircon, Monazite, Sillimanite) ,Gold, Iron ore, Bauxite, Graphite, China Clay, Fire Clay, Tile and Brick Clay, Silica Sand, Lignite, Limestone, Limeshell, Dimension Stone (Granite), Gemstones, Magnesite, Steatite etc. However, mining activities on large scale are confined mainly to a few minerals – Heavy Mineral Sands, China Clay and to a lesser extent Limestone/Limeshell, Silica Sand and Granite. In fact, Heavy mineral sand and China Clay contribute more than 90% of the total value of mineral production in the State

Solution: B
Justification: Limestone is a sedimentary rock consisting primarily of calcium carbonate in the form of the mineral calcite. Aragoniteis also found which is a different crystal form of calcium carbonate (CaCO3). The only mineral found of importance is Lead. The process of chemical weathering of bedrock in which the combination of water and acid slowly removes mineral compounds from solid bedrock and carries them away in liquid solution makes it difficult for limestone to host minerals.
