The world’s largest mountain ranges, known as the “Young Fold Mountains” (like the Himalayas, Alps and Andes), were formed approximately 30 million years ago during the Tertiary period. This “Alpine Orogeny” was driven by intense plate tectonic collisions. These mountains ...
Among the options, the Rockies are the youngest mountain range. They are part of the “Young Fold Mountains” formed during the late Cretaceous to Tertiary periods. In contrast, the Urals and Appalachians are ancient ranges (Paleozoic era) that have been ...
Leopold Kober propounded the Geosyncline Theory of mountain building. He described “Geosynclines” as long, narrow, mobile zones of water that collect massive amounts of sediment. Kober argued that the contraction of the Earth’s crust causes the rigid masses (kratogens) on ...
The Radioactivity Theory of mountain building was propounded by John Joly in 1925. He suggested that the heat generated by the decay of radioactive elements (like Uranium and Thorium) within the Earth’s crust causes the periodic melting and expansion of ...
