‘If Ryskin is right, then climate change, predicted to alter the strength and course of ocean currents, could also alter the planet’s magnetic field. ‘
Catastrophe or hollow earth ping.
Diameter of earth at equator = 7926 miles
radius of earth at equator = 3963 miles
Volume of earth = 4/3*pi*R^3 = 260,711,886,825 cu mi
Assume average ocean depth of 2.7 miles (based on size and average depth of each ocean) and water coverage of 71%
Volume of ocean = 71%*4/3*pi*(3963^3 - 3960.3^3)
= 71%*4/3*pi* (62240377347-62113250509)
= 71%*4/3*pi* 127126838
= 71% * 532507661
= 378080439 cu miles
Ratio of Ocean to Earth volume
= 378,080,439 / 260,711,886,825 = .145%
Ratio of solid Earth to Earth volume = 99.855%
I would think the effect of such a small percentage of the earth's mass would have a neglible effect on earth's magnetic fields.
Anyone else have any thoughts?
