OrderIt is essential to understand plate motions. Plate movements often occur within the tectonic plates along narrow zones where the effect of the plate tectonics are very evident. For instance convergent boundaries always occur where one continental or oceanic plate dives under each other. In convergent zones, the earth’s crust is destroyed within the earth’s interior where the plates which are lighter in density dive under another. These are refereed to as subduction zones. A good example on earth where there are convergent boundaries is the boundary between the Eurasian plate and the Indian plate. These are good examples of continent-continent convergent zones.

Write My PaperThis tectonic movement occurs where neither of the plates is subducted since the rocks are very light to be moved into the heavier mantle. When the two continental plates meet head on, and because of their relatively light density, they are often pushed up and sideways. This movement may result into folding and buckling of the tectonic plates. As a result, the tectonic crust cramps into tectonic mountain ranges, hence, exposing the deep-seated sedimentary rocks such as granites, and gneiss, with relatively minimal volcanic activity.
The tectonic movements cause alterations to the land. For example, the collision of Indian plate caused the Eurasian plate to crumple and override the Indian plate. The collision was followed by a slow and continuous convergence of the two plates, which pushed up the Himalayas and the Tibetin plateau, in their present form and heights. The Indian plates tend to move in northward direction raising the Himalayan and the Tibetian highlands. Other changes also include the disappearance of the sea that had existed before as the lad begins to rise as the Eurasian plate began to fold as it arises over the Indian plate. The plates have continued to convergence, causing pressure on the sedimentary rocks such as granite and gneiss, and other rocks of the ancient sea to rise until they caused the Himalayan and the Tibetian plateau. It is expected that these tectonic movements will continue in the future; hence causing the Himalayas to continue to rise in height. In other regions, the tectonic movements may also result into cracks, which have been observed at the great foldbealt that stretches from China to Turkey. Other examples are also occurring in the Southeastern Alaska which has been classified as areas of extreme tectonics.
Presently, the Himalayas is approximately 8,854 meters above the seal level, and has been observed as the highest continental mountains in the world. Furthermore, the Tibetian plateau, with an average height of about 4,600 meters above the sea level, is the highest than all other peaks in the Alps, and well above most mountain summits in the U.S.A.The figure below explains the tectonic movement between the Indian and the Eurasian plate up the Himalayas and the Tibetian plateau.
