Just a little fun water fact for Xmas.
97% of the world's #water is salty (the oceans).
Of the 3% freshwater, the vast majority is locked up in ice caps, glaciers, & deep groundwater. Only a tiny fraction of 1% is accessible in rivers, lakes, groundwater, & rain. Use it carefully.
TBF, estimates of the water content of the lower crust and mantle are poorly constrained. There is likely many times more water there than there is in the oceans. Supercritical water is the lubricant of Earth's tectonic engine.
One day the mostr stuff will be able to see our responses.
