Extreme Environments - Season 1 Episode 23 Mountain
0.00 48 minutes Roughly one quarter of the Earth’s surface is covered by mountains. More than half of the world’s population depends on the rivers that
are fed by the ice and snow that form in mountain ranges. Some mountains are formed by volcanic action, but mountain ranges result
from the compression of the Earth’s Tectonic Plates. The Himalayas, which lie between India and Tibet, are the highest mountain
systems, and the “youngest”.
