'Land, Sea and Air' Part 1 - How mountains are made

Rock climber, mountaineer and geologist, Professor Mike Searle, explains how his work to understand mountain ranges, particularly the Himalayas, can unearth clues about the origins of mountains. From trekking across mountains to map them, to using new technology to understand how the continents have moved in the past, and how they're behaving today. He also discusses last years tragic Earthquake in Nepal. Read more about his work at http://www.travelinggeologist.com/tg-mike-searle/.
