Question
Answer the following questions in brief
State two chief differences between old and young fold mountains. Give examples.
Solution
The mountains which were formed over 250 million years ago due to compression of earth’s crust are called old fold mountains. They have gentle slopes and low altitude due to weathering over time eg. The Urals in Russia, Aravallis in India, and the Appalachians in India.
The recently formed mountains i.e. about 25 million years ago are called young fold mountains. They are rugged and lofty. They comprise the world’s highest mountain ranges.
Eg. Rockies of North America, Alps, Andes, Himalayas, and The Great Dividing Range.
