Question

what are the benefits of gaps and passes in the mountains ​

Answer 1

Answer:

A mountain pass is a navigable route through a mountain range or over a ridge. Since many of the world's mountain ranges have presented formidable barriers to travel, passes have played a key role in trade, war, and both human and animal migration throughout Earth's history. At lower elevations it may be called a hill pass. The highest vehicle-accessible pass in the world appears to be Mana Pass, located at 18,478 feet above sea level in the Himalayas on the border between India and China.

Answer 2

A pass is a gap, or break, in high, rugged terrain such as a mountain ridge. ... Passes often provide the easiest routes for people to travel across steep mountain ranges. For this reason, they have played an important role throughout human history in migration, trade, and settlement.
