Aravalli ranges MCQ — 2 Practice Questions with Answers

Explanation

Gurushikhar is the highest peak of the Aravalli Range and lies in the Mount Abu area of Sirohi district. Its height is generally given at about 1,722 metres, making it clearly higher than the other listed peaks. Raghunathgarh is a known Aravalli peak in the Shekhawati region but is lower. Jagra and Kamalnath are also associated with the Aravalli system, yet neither reaches the elevation of Gurushikhar. The question is therefore answered by relative height within the Aravalli Range.

Explanation

The true statements are that the Aravalli range is now regarded as a residual mountain and that its general alignment is from the south-west to the north-east. The Cambrian-age statement is not accepted in the usual Rajasthan geography framing; the Aravallis are treated as much older than that. The claim that the range is mainly made of igneous rocks is also wrong, because its geology is largely associated with ancient metamorphic and related rock formations. Therefore the valid combination is the residual-mountain statement with the south-west to north-east extension.
