tectonic plates move because they are floating on top of the mantle. the mantle itself moves due to convection currents: hot rock rises gives off some heat then falls. this creates vast swirls of moving rock under the crust of the earth which jearth science 101: earth science courseonline video earth science 101: earth science has been evaluated and recommended for 3 semester hours and may be transferred to over 2000 colleges and
the earth's crust is a thin shell on the outside of the earth accounting for less than 1% of earth's volume. it is the top component of lithosphere: a division of earth's layers that includes the crust and the upper part of the mantle. the lithosphere is broken into tectonic plates that move allowing heat to escape from the interior of the earth into space.5 things that will not happen in the futurereturn of kingsdec 30 2015· economic forces suggest to me that if left reasonably well enough alone will see us mining asteroids or the moon or wherever soon enough.its taught in every texas history class from early childhood on through high school that texans have the right to declare independence from the usa. id bet half of all texans would vote to leave
