Tectonic Plates In Nepal

Earth science - tectonic plates in Nepal

Introduction:

Slide 1-What they are?

Tectonic plates are the lithosphere of the earth, they are divided into a small number of plates around world. The lithosphere includes the crust and outer part of the mantle. Below the lithosphere is the asthenosphere, which is partially malleable, allowing the lithosphere to move around. Some plates have countries in the middle on for example like Australia and others sit on the fault lines of the other tectonic plates. These plates float and travel independently over the mantle and the earth 's seismic activity occurs at the boundaries of these plates. These plate tectonics move continents higher and lower making mountains grow slowing and country move further

The study of plate tectonics has suggested that earthquakes, mountains, climate, and many other geological occurrences are directly linked to these tectonic plates moving. There are different types boundaries such as divergent which plates move away from each other creating volcanoes, transform boundaries which plates slide past each other causing earthquakes and lastly convergent boundaries which plates move towards each other making the ground lift and causing lots of

Nepal is on a thrust plate which means when the tectonic plates move or slide along each other to make it shake the ground causing earthquakes and other natural disasters. The Indo-Australian plate is a large crustal plate that includes the continent of Australia and the sub-cotenant of India. The Indian plate and the Australian plate fused about 43 Ma, stretching from Antarctica in the south to the Himalayas, the Indonesian islands and New Guinea in the north, to New Zealand in the east. It is currently moving the North- east at about 7cm per year. Shingling effects occur when tectonic plates collide and create thrust faults which is what Nepal’s faults are.

Reason why:

Slide 8-Analyse

From the evidence that has been conveyed, Nepal’s earthquakes and volcanoes are caused by the the Indo-Australian and Asian plates. These plates are transform plate boundaries which can explain all the earthquakes and mountains featured in Nepal. The reason for every earthquakes and mountain range is due to these plates colliding, these plates are rough therefore sending out stressed waves which are very strong when jolted fast. This is called a compression fault. Evidence between Nepal and japan are
