Question

The Vindhya range is made up of what type of rocks?
A) Igneous rocks
B) Sedimentary rocks
C) Metamorphic rocks
D) None of the above

Answer 1

Hint: A mountain range, also known as a hill range, is a line of mountains or hills connected by high ground. A mountain system, also known as a mountain belt, is a collection of mountain ranges that are similar in form, structure, and alignment and have a common origin, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but the majority of the world's major ones are found in the Himalayas

Complete answer:
In west-central India, the Vindhya Range is a complex, discontinuous chain of mountain ridges, hill ranges, highlands, and plateau escarpments.

In geological terms, the Vindhyas do not constitute a single mountain range. The Vindhyas are a loosely defined hill system in central India that historically covered a number of distinct hill systems, including the one that is now known as the Satpura Range. Mountain ranges can be found on many of the Solar System's planetary mass objects, and they are almost certainly a feature of most terrestrial planets.

Highlands, mountain passes, and valleys usually divide mountain ranges. Individual mountains in the same range may or may not have the same geologic structure or petrology.They could be a mix of orogenic expressions and terranes, such as thrust sheets, uplifted blocks, fold mountains, and volcanic landforms, resulting in a wide range of rock types.

The Narmada-Son valley runs parallel to the Vindhya range. The elevation ranges from 300 to 650 meters. The majority of them are made up of ancient sedimentary rocks. Between the Gangetic and peninsular river systems, they serve as a watershed.

Hence, the correct option is (B) i.e, Sedimentary rocks.

Note: Vindhya river forms the southern wall of the Malwa plateau in Madhya Pradesh, running roughly parallel to the Naramada river in an east-west direction. The range divides into branches east of Malwa, resulting in multiple chains in the eastern Vindhyas.
