DAILY CURRENT AFFAIRS QUIZ – 22 November 2024

Ans. c

Explanation:

Factors Influencing Temperature Variations:

1. Location in Relation to the Sea

• Influence on Temperature: A location’s proximity to the sea significantly impacts its temperature. Compared to land, the sea undergoes a slower heating and cooling process, resulting in less temperature variation. Areas near the sea benefit from the moderating effects of sea and land breezes, which help regulate temperature fluctuations.

2. Effects of Air Masses

• Impact on Temperature: Temperature is also influenced by the movement of air masses. Areas affected by warm air masses typically experience higher temperatures, whereas those affected by cold air masses record lower temperatures. Similarly, coastal regions influenced by warm ocean currents exhibit higher temperatures than areas influenced by colder ocean currents along the coastlines.

Ans. d

Explanation:

Winds with Distinct Characteristics:

1. Mistral

• Description: Mistral, a cold and dry powerful wind in southern France, blows from the north along the lower Rhône River valley towards the Mediterranean Sea. It sustains for extended periods, averaging approximately 74 km/h (45 miles/h), primarily prevalent and most forceful in winter, sometimes leading to significant crop damage.

2. Pampero

• Description: Pampero, a cold and dry wind occurring in the Pampas region (Argentina) during winter, results from a burst of cold polar air sweeping westward, southwestward, or southward over the pampas across South American countries like Brazil, Argentina, Uruguay, Paraguay, and Bolivia. Associated with a passing cold front of an active low, it intensifies into a squall line, causing a noticeable temperature drop. In Buenos Aires, these storms during summers serve as a welcomed relief from high humidity and extreme heat.

3. Simoon

• Description: Simoon, a scorching, arid, suffocating, and dust-laden wind, ravages African deserts, notably impacting regions like Arabia, Syria, and neighboring countries. Generated by extreme desert heat, it carries dust and sand, reshaping deserts and sand dunes during late Spring and Summer. Despite its brevity, lasting around 20 minutes, it can result in whirlwinds, predominantly due to low-level thermic heating, significantly impacting desert landscapes.

Ans. a

Explanation:

Cumulonimbus Cloud Characteristics:

1. Cloud Structure and Height

• Description: Cumulonimbus clouds stretch extensively upwards in towers or plumes, commonly recognized as thunderclouds due to their unique ability to generate hail, thunder, and lightning.

2. Distinctive Features

• Appearance: These clouds typically exhibit a flat base, accompanied by a dark, wall-shaped structure hanging beneath. The cloud base might be positioned just a few hundred feet above the Earth’s surface.

3. Formation and Convection

• Origin and Development: Cumulonimbus clouds originate from convection processes. They can also form along cold fronts, specifically due to forced convection, where warmer air is compelled to ascend over incoming cold air masses.

Ans. d

Explanation:

Tropical Cyclones: Characteristics and Factors

1. Nature and Impact

• Description: Violent storms originating over tropical oceans, causing significant devastation upon reaching coastal areas due to fierce winds, intense rainfall, and storm surges.

2. Wind Movements in Tropical Cyclones

• Statement 1 (Incorrect): Wind patterns within tropical cyclones run counterclockwise in the northern hemisphere and clockwise in the southern hemisphere, attributed to the Coriolis Force.

3. Conditions Favorable for Formation

• Statement 2 (Correct): Favorable conditions for tropical cyclone genesis include expansive warm sea surfaces with temperatures surpassing 27°C, sufficient Coriolis force to generate a cyclonic vortex, minimal fluctuations in vertical wind speed, presence of a pre-existing weak low-pressure zone, and upper-level divergence over the sea.

4. Characteristics of the ‘Eye’

• Statement 3 (Correct): The ‘eye’ represents a circular region within a severe tropical cyclone, characterized by relatively calm winds and fair weather. It typically lacks precipitation and occasionally displays clear skies or star visibility. The eye denotes the area with the lowest surface pressure and highest temperatures at upper levels.

Answer D

Current Account Deficit (CAD):

• Definition: The current account deficit (CAD) occurs when the value of a country’s imports of goods and services is greater than its exports.
• Significance: CAD, when combined with fiscal deficit, forms twin deficits that can impact the stock market and investors.

2. Fiscal Deficit:

• Definition: Fiscal deficit is the gap between the government’s expenditure requirements and its receipts. It represents the money the government needs to borrow during the year.

3. Implications of CAD:

• Economic Impact: CAD significantly affects the economy, stock markets, and people’s investments.
• Investor Sentiment: A lower CAD can boost investor sentiment and make the country’s currency more attractive to investors.
• Surplus in Current Account: A surplus in the current account indicates money flowing into the country, boosting foreign exchange reserves and the local currency’s value.

4. Recent Status of India’s CAD:

• CAD in 2022-23: The CAD for the first half of 2022-23 was 3.3% of GDP. However, the situation improved in Quarter 3:2022-23 due to lower commodity prices and moderated imports.

5. Negative Effects of CAD on Economy:

• Weaker Currency: When a country’s imports exceed exports, it can lead to a weaker currency value (depreciation), affecting demand for the currency.
• Inflation Impact: Weaker currency makes imports more expensive, contributing to higher inflation and a reduction in purchasing power.
• Debt Accumulation: Inability to finance CAD with foreign investment may lead to borrowing, increasing debt levels and potentially harming the economy.
