Question

Among the following identify block mountains of india
A)Aravalli
B)Himalaya
C)Satpura and vindhya
D)None of these

Answer 1

Hint: When two tectonic plates move away from each other, creating cracks on the surface of the Earth, Block Mountains are formed. The strip of land or the block of land between them can be raised when simultaneous cracks or failures occur, resulting in the creation of block mountains. An horst is called the upward block.

Complete answer:
Among the ranges given, the Satpura and Vindhya ranges fall under the Black Mountains category. These two ranges are situated in central-western part of india. Black mountains are the mountain ranges that are created from the cracks/faults produced from the crust of the earth, also known as fault black mountains. These faults or cracks cause the rise of one portion or part of the earth and the depression of others, thus creating block mountains.

Lets see options :
Aravali : The Aravalli Range is the oldest folded mountain range in India which is an eroded stub of ancient mountains. Thus this option is wrong.
Himalaya : Himalaya is a folded mountain thus this option is wrong too.
Satpura and vindhya : Satpura and vindhya ranges fall under the block mountains category thus this option is correct.
None of these : Option C is the correct answer thus this option is wrong.

Hence, the correct answer is option (C)

Note: Vindhya range :
1)The Vindhya Range, which is more or less parallel to the Valley of Narmada.
2)It is 1,200 km east-west from Jobat in the state of Gujarat to Sasaram in the state of Bihar.
3)The Vindhya Range's estimated elevation is about 300 to 650 m.
