collision
The earth's crust sinking in is called subduction. It is usually associated with tectonic plate movement. When one plate slides over another and pushes the other downward.
its the techtonic plates. one plate slides over the other which = trust from action
A bendix.
The downward movement of the more dense plate beneath the less dense plate in a convergent plate scenario is called subduction.Conversely, the over thrusting of one plate onto another is known as obduction.
the coefficient of friction
The December 26, 2004 tsunami occurred at a plate boundary, a few miles off the coast of Sumatra, Indonesia. A natural sensation called 'subduction' occurred. That is when a plate slides over or under another plate. There was an earthquake and also a displaced water mass trying to regain it's equilibrium position. Shockwaves were sent in all directions.
normal fault i think
yes, all land masses are on one tectonic plate or another.
The 2004 and 2011 tsunamis were the result of something called megathrust earthquakes. Off the coasts of Sumatra and Japan, where the tsunamis originated, there are subduction zones, places where one tectonic plate pushes into and slides under another. For the 2004 tsunami it was the Indian Plate sliding under the Eurasian Plate. For the 2011 tsunami it was the Pacific Plate sliding under the Okhotsk Plate. As this happens the plates become snagged on one another and distort under the force of it, building up tension over the course of a few hundred years. Eventually the plates snap back into place, triggering a major earthquake. This results in part of one plate being thrust upward, displacing an enormous column of water and creating a tsunami.
The word you're looking for is.... friction
Earth's land surface is built up by a process called tectonic subduction.Related Information:This process occurs as one tectonic plate is subducted (slips under) another, while the subducting plate is elevated as it moves over the subducted plate. The subducted plate is most commonly a oceanic plate.
