They influence the direction of winds, precipitation, and other atmospheric processes.

What is the significance of mountains in terms of water sources?

Mountain ranges are the source of perennial rivers due to snow and glaciers.

What is the relationship between landforms and biodiversity?

Different species of plants and animals thrive in various landforms, contributing to biodiversity.
