Seismologist Micheal Wysession learned this new ocean by examining more than 600,000 seismograms.
Wysession found the waves on the siesmograms began to diminish in 1 place beneath Asia. Usually, seismologists used a kind of CAT scan by measuring the speed of seismic waves (Anitei printout 1). “Drinking water slows the velocity of the waves a little”, Wysession explained.
“Plenty of dampening and a little slowing match the predictions for h2o pretty perfectly” (Than printout one). Predictions were evaluated stating that a cold slab of the ocean floor could have sank miles into the Earth’s mantle leaving the warm temperatures of the mantle to evaporate water stored in the rocks. When the water rises it appears to be a solid formation but the composition of rock in the ocean is stated to be 15 p.c water.
