Question

Aravalli ranges are an example of ……………………………..
A- Straight mountain
B- Block mountain
C- Residual fold mountain
D- Volcanic mountain

Answer 1

Hint:
It is a mountain range in northwestern India, moving in a south-west direction for approximately 692 km.
It is the oldest mountain in India’s geographical structure.
These hills are spread across four states of India – Rajasthan, Haryana, Gujarat and Delhi.

Complete answer:
Option A) Straight mountain – is an incorrect answer because it is an unincorporated community in Blount County, Alabama, United States. For its uncommon place name, the straight mountain has been noted. Aravalli ranges are not an example of Straight mountain. It is incorrect here.

Option B) Block mountain – is an incorrect answer because block mountains are formed when large areas of blocks of earth are broken and subside vertically. It is an obsolete term to indicate a mountain that has been left standing on either side while the central portion slumps. It is incorrect here.

Option C) Residual fold mountain – is a correct answer because Aravalli ranges are an example of Residual fold mountain. The consequence of the erosion of an established elevated region is the creation of residual mountains. They are sometimes called mountains of denudation. Residual mountains are called the rough rocks that are left behind. Example: the Aravalli range, the rajmahal hills, the Nilgiri mountains, etc.

Option D) Volcanic mountain – is an incorrect answer because a volcanic mountain starts out as a simple crack in the earth called a volcanic vent. Magma explodes as lava flows, ash clouds, and explosions of rock from the earth. This material falls around the vent back to earth and piles up around it. Over time, a volcanic mountain builds up with the familiar cone shape. It is incorrect here.

Therefore the correct answer is C

Note:
The Aravalli range’s literal sense is ‘line of peaks’.
It is the oldest mountain range in the world.
Natural resources are very rich in the Aravalli range. Aravalli ranges are an example of Residual mountains.
