[MISSION 2024] RTM(Revision through MCQs)- 23 November 2023

Ans: (b)

Explanation:

• Context: Tantalum, a rare metal, has recently been discovered in the Sutlej River by an IIT Ropar team
• Tantalum is often used in the production of high-performance alloys due to its excellent corrosion resistance and high melting point. These alloys find applications in aerospace, particularly for manufacturing components in aircraft and missiles.

Ans: (a)

Explanation: What is Near Space ?

• Near space is the region between 75,000 feet (23 km) and 62.5 miles (100 km). It’s also defined as the area between airspace Flight Level 600 (18 km) and 160 km above sea level.
• Near space is too thin for planes to fly in, so military planes avoid it.

Ans: (a)

Explanation:

• A cyclone, commonly known as a low, is an area of low pressure where air masses meet and rise. An anticyclone, commonly known as a high, is an area of high pressure where air moves apart and sinks.
• Cyclone typically indicates bad weather, like rain and clouds whereas anticyclone indicates fair weather.

Ans: (b)

Explanation

• Most cyclones are forced to weaken post landfall as they detach from the sea.
• Cyclones are formed between the tropics while western disturbances are formed in the mid-latitudes. When the two interact, they influence each other. When cyclones come under the influence of western disturbances, it can retain its intensity even after entering land.
• Cyclone Tauktae in 2021 came under the influence of western disturbances, it slowed down as it was crossing over to land. This slow progress over the coast ensured that the cyclone continued to get sufficient moisture supply from the sea. Hence it did not weaken, but rather retained its intensity even 24 hours after coming over land.
• The Bay of Bengal and the Arabian Sea generate only 7 per cent of the world’s cyclones. However, their impact are huge as some of the most densely populated regions of the world, including some mega-cities, are susceptible.

Ans: (c)

Explanation

• Tropical cyclones can relieve drought conditions as they often carry moisture laden winds.
• In addition to strong winds and rain, tropical cyclones are capable of generating high waves, damaging storm surge, and tornadoes.
• They typically weaken rapidly over and where they are cut off from their primary energy source. For this reason, coastal regions are particularly vulnerable to damage from a tropical cyclone as compared to inland regions.
• Heavy rains however, can cause significant flooding inland, and storm surges can produce extensive coastal flooding up to 25 miles from the coastline.
• They also carry heat energy away from the tropics and transport it toward temperate latitudes, because they are large wind systems that absorb the frontal conditions of the area they flow in.
• Finally, due to the high speed they blow in, they also act as the earth’s filter system by cleansing the air of toxins and pollutants out of the atmosphere.
