What are the different types of tectonic boards?
tectonic plates are large, disconnected pieces of the Earth's crust, hovering on the cloak below, composed of soft magma. Tectonic plates differ very much in thickness depending on whether they are oceanic (about 5 km or 3 miles) or continental (about 50 km or 30 mi). The continental bark generally consists of lighter rocks, while the ocean bark consists of heavier rocks. This means that when the ocean tectonic board collides with a continental board, it will certainly slip under the continental plate or to be subjected.
There are three main types of tectonic plates boundaries described in terms of the way the tectonic boards move in relation to each other. These include the boundaries of the transformation, where the boards grind in parallel with each other, different boundaries where the boards move apart and convergent boundaries, where the boards push into and sometimes below. These boundaries of the albums result in mistakes, valleys torn, ocean ridges, ocean trenches, mountains, island arches, subdzoly uctus, SOPKY and other geological phenomena.
An example of the transformation limit between tectonic plates is San Andreas in California. Here the Pacific plaque moves in the northwest with regard to the North American album. The boundaries of transformation are often accompanied by earthquakes caused when stress accumulates between the boards and suddenly releases in minutes or seconds. The primary earthquake may be followed by several shocks, smaller shocks that continue to release crust stress after the primary earthquake.
An example of a divergent border is a central -Atlantic ridge in the middle of the Atlantic Ocean. Here the bark is divided at a speed of about 5 cm (2 inches) per year. It will be replaced by the magma rising under the bark and rapidly stiffening, creating a number of ridges that give the middle ridge its name. The island of Iceland is an example of a part of the ridge that is over the water.
an example of convergent playCE are Himalayas, including the highest mountain in the world, Mt. Everest. Here the Indian album is pushing north into the Eurasian plaque, under it undergoing and causing it to rise. For this reason, the Himalayas actually grow about a thumb every year.
