Read the statements given below carefully :
Statement 1: The Deccan Trap region of the Peninsular Plateau is covered with black soil derived from igneous rocks.
Statement 2: The Aravalli Hills are newly formed folded mountains stretching from Gujarat to Delhi.
Which of the above statements is/are correct?
Show answer & explanation
Correct answer: A
Explanation
Correct Answer:
Only 1
Explanation:
Statement 1 is correct. The Deccan Trap region of the Peninsular Plateau is formed by extensive volcanic (igneous) basaltic lava flows. The weathering of these igneous rocks has led to the formation of black soil (Regur soil), which is highly fertile and especially suitable for cotton cultivation.
Statement 2 is incorrect. The Aravalli Hills are not newly formed fold mountains. They are among the oldest mountain ranges in the world and are highly eroded. They extend from Gujarat to Delhi and are considered residual mountains rather than young fold mountains.
Key Points:
• Deccan Trap is made up of volcanic igneous rocks, mainly basalt.
• Black soil in this region is formed due to weathering of basalt.
• Aravalli Hills are one of the oldest mountain ranges in India.
• They are not young fold mountains but residual, heavily eroded structures.
Additional Facts:
• The Deccan Traps were formed due to massive volcanic eruptions millions of years ago.
• Black soil is also known as Regur soil.
• Guru Shikhar in Mount Abu is the highest peak of the Aravalli Range.
Important Questions:
Q1: Black soil is formed from which type of rocks?
Ans: Igneous (basalt) rocks.
Q2: What type of mountains are the Aravallis?
Ans: Old residual mountains.
Q3: How was the Deccan Trap formed?
Ans: By volcanic igneous activity.
