The Hindu Kush separates Central Asia from where?

Question

A roughly east-west belt of what, separates the land mass of central Asia from the northward-travelling land mass of India and its neighbours?

Answer 1

The Hindu Kush is one of the great watersheds of Central Asia, forming part of the vast Alpine zone that stretches across Eurasia from east to west. It runs northeast to southwest and divides the valley of the Amu Darya (the ancient Oxus River) to the north from the Indus River valley to the south.
