DAILY CURRENT AFFAIRS QUIZ – 5 May 2025

Answer C

Igneous Rocks or Primary Rocks

1. Formation of the First Rocks:
   • The first rocks on Earth were formed through the solidification of magma.
2. Definition of Igneous or Primary Rocks:
   • Rocks formed from the solidification of magma (molten rock below the surface) and lava (molten rock above the surface) are known as igneous or primary rocks.
3. Unfossiliferous Nature:
   • Igneous rocks have their origin under conditions of high temperatures, and as a result, they are unfossiliferous.
4. Examples of Igneous Rocks:
   • Some examples of igneous rocks include granite, gabbro, and basalt.
5. Types of Igneous Rocks Based on Cooling:
   • There are three types of igneous rocks based on the cooling of the molten matter: plutonic rocks, volcanic rocks, and intermediate rocks.
6. Types of Igneous Rocks Based on Acid-Forming Radical:
   • Igneous rocks are also categorized into acidic rocks and basic rocks based on the presence of acid-forming radical, silicon.
7. Intrusive Igneous Rocks (Plutonic Rocks):
   • If magma cools slowly at great depths, it results in the formation of intrusive rocks or plutonic rocks.
   • These rocks often have very large mineral grains.
   • Example: Granite.
   • These rocks become visible on the surface only after they have been uplifted and exposed through denudation.
8. Extrusive Igneous Rocks (Lava or Volcanic Rocks):
   • Rapid cooling of magma just below the surface or lava above the surface leads to the formation of extrusive rocks or volcanic rocks.
   • These rocks typically have small and smooth grains due to the rapid cooling process, preventing crystallization.
   • Example: Basalt.
   • The Deccan traps in the Indian peninsular region are of basaltic origin.
9. Basic Rocks:
   • Basic rocks contain a higher proportion of basic oxides, such as iron, aluminum, or magnesium.
   • As a result, they are denser and darker in color.

Answer: (c) 1 and 2 only

Explanation:

Statement 1 is correct; Tranquebar, Serampore, and the Nicobar Islands were indeed Danish colonies in India.

Statement 2 is correct; Serampore served as the primary headquarters for the Danish in India.

Statement 3 is incorrect; the Danish involvement in India began with Marcelis de Boshouwer’s appeal for military assistance against the Portuguese, not the Dutch.

Answer:

(d) Neither 1 nor 2

Explanation:

1. Statement 1 is incorrect. The recent amendment under the RBI’s Liberalised Remittance Scheme (LRS) includes the overseas use of credit cards by Indian residents within the $250,000 limit, not debit cards.

Statement 2 is incorrect. The LRS allows resident individuals to remit up to $250,000 per financial year for any permissible current or capital account transactions, and it is indeed not available to Corporates, partnership firms, HUF, and Trusts.

Answer: (a) 1 and 2 only

Explanation:

• Statement 1 is correct. The Curiosity Rover is a part of NASA’s Mars Science Laboratory (MSL) mission.
• Statement 2 is correct. The Curiosity Rover was launched in the year 2012.
• Statement 3 is incorrect. It is the largest and most capable rover ever sent to Mars.
