Hard to fathom how "fluid" our ball of magma really is.
" The mass of ice on the earth's poles has also led to the shape of the planet via tectonics over thousands of millennia. As that mass melts and redistributes from a solid to a liquid spreading around the globe our spheroid will begin to rebound. We have sensors everywhere, even in space, so the resulting effects will not be a surprise to some when the 'mass'ive shift begins. As those tectonic events increase in frequency so too will volcanic activity so I ask if anyone else has been checking on such data? "
