b. they provided a means for contact with outside cultures.
c. they increased communication between china and india.
d. they prevented winds from gobi from deteriorating regional soil.

The correct answer is A) they served as a protective barrier.

The Himalayas affected earlier civilizations in China and Asia in that they served as a protective barrier.

The Himalayas were the perfect natural barrier that served as protection for Asian countries, especially China. But those great peak mountains were not the only natural barriers that protected China from invasions. To the West, it is the Taklamakan Desert, to the Southeast the China Sea, and to the Northeast, the Yellow Sea. Chinese people only had to worry about the Northside that is a huge plain.
