or in other words, diverging plates.

Try http://www.geo.lsa.umich.edu/~crlb/COURSES/270/Lec12/Lec12.html\nIt helped me do my homework! Also, it has pictures of plate boundries and plate tectonics. Hope it helps!

b) changes\n\nwhen a plate moves it can do a number of things. it can make a mountain, volcano, island, etc.\n\nit doesnt collapse (stupid answer), it wont melt (why would it? all thats happening is a plate moving, that wouldnt melt earth) and it doesnt shrink just because it moves.

Introduction\nPlate tectonics is a relatively new theory that has revolutionized the way geologists think about the Earth. According to the theory, the surface of the Earth is broken into large plates. The size and position of these plates change over time. The edges of these plates, where they move against each other, are sites of intense geologic activity, such as earthquakes, volcanoes, and mountain building. Plate tectonics is a combination of two earlier ideas, continental drift and sea-floor spreading. Continental drift is the movement of continents over the Earth's surface and in their change in position relative to each other. Sea-floor spreading is the creation of new oceanic crust at mid-ocean ridges and movement of the crust away from the mid-ocean ridges.

other animals ....of course.\n\nDo you know about plate tectonics?

none they work eccentrically in the down phase

All depends on the magnitude and the location of the earthquake along the fault.

The continental plates do not actually 'drift' as you may think of an ice cube 'drifting' in water. Nor are the plates all connected together like one would view a jigsaw puzzle.\n\nThe first idea you have to realize is that the continental plates overlap each other. The 'outlines' you see that appear jigsaw-like are more often than not areas where two plates meet, and one plate is actually going under  the one next to it- this is called 'subduction'.\n\nWhich plate goes under which plate depends on the age and weight of the plates-- continental crust is lighter than oceanic plate, so more often than not it is the oceanic piece of the plate that will 'subduct'.\n\nThere are areas, however, where the plates do actually meet like a jigsaw puzzle-- these places are known as "Strike-slip" faults, where two plates slide past each other rather than 'subducting'.\n\nAs for the plates moving, that happens due to the upper mantle (the liquid part under the crust) creating convective currents-- these 'currents of mantle material' cause the plates to move and subduct (or slide past each other!)\n\nAnd yes, there are plates where continental crust and continental crust meet. What happens then? More often than not, mountains form-- The Himalayas are a prime example of this situation (the Indian plate smashed into the Asian plate).\n\nThere's more to it, but I hope this helps a little bit!

Plate tectonics is the process by which the crustal plates constantly move about, collide, diverge, and, in the process, and recycle themselves to/from the mantle; Earth is the only planet known at the moment that has such processes. I can't simplify it much more, I'm sorry.

I think its called 'subduction', where one tectonic plate goes under another. It occurs at 'subduction zones', such as on the west coast of the United States. The reason it occurs is that one plate is expanding and the edges need to go somewhere (under another plate). For example, the Atlantic plate is expanding from the center because there is a north-to-south line of underwater volcanoes, spewing out magma and forcing the 2 halves of the plate apart to the west and east.

Giant rock plates pushing against each other suddenly slip causing the earth to move, sending out ripples like in a pond.\n\nChildren can recreate the action of a fault slipping with their hands.  Place both hands together, palm-to-palm.  Push the palms together.  While pushing the palms together, slide one hand forward away from the body while sliding the other hand back toward the body.  At first, nothing will happen.  As force is added to the forward-backward movement, the hands will suddenly slip, much as the earth does during an earthquake.

The magnetic striping of the seafloor is similiar on both sides of an oceanic rift.  They match up like puzzle pieces.

There is, it is called Standarad Deviation, if you have a decent Scientific Calculator it shouyld show how to use it.

centre of gravity of both pans along with arms of the balance lies just below the fulcrum,when it is tilted ,the centre of gravity tries to balance the weight hence stops with a little tilt.
