Week 5:

Volcanoes when it comes to Nepal is the least of its worries as geographically, there is little to no hazards surrounding the country. Despite residing on tectonic plate collision zones, ( The Himalayas) in the form of the Indian subcontinent and the Asian Super continent which are always colliding, there are virtually no Volcanoes in Nepal! As a result of the absence of Volcanoes, an abundance of earthquakes takes its place. This is due to the converging tectonic plates colliding with just pure dry rocks and no water in place in order to melt. Water decreases the melting point of rocks. When water is conveyed into deep Earth, solid rock may melt. The making of a volcano requires magma, molten rock, with the absence of water entirely there is no molten rock which means there is no magma and no-volcanoes. Because the rock making up continental plates is generally lighter and less dense than oceanic rock, it is too light to get pulled under the earth and turned into magma. Instead, a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges.
