Consider the following information:

	Region	Name of the mountain range	Type of mountain
1.	Central Asia	Vosges	Fold mountain
2.	Europe	Alps	Block mountain
3.	North America	Appalachians	Fold mountain
4.	South America	Andes	Fold mountain

In how many of the above rows is the given information correctly matched? 

The correct answer is Option 2.Key Points

• The Vosges Mountain in Europe (not in Central Asia) is an example of block mountain systems. Block Mountains are created when large areas are broken and displaced vertically. The uplifted blocks are termed as horsts and the lowered blocks are called graben. Hence, Pair 1 is incorrect.
• The Alps is one of the youngest fold mountains with rugged relief and high conical peaks located in Europe. Hence, Pair 2 is incorrect.
• The Appalachians in North America is one of the very old fold mountains in the world. Hence, Pair 3 is correct.
• Andes is one of the youngest fold mountains located in South America. Hence, Pair 4 is correct.
