If everything happened like you described, how could Noah’s Ark have survived such an event? The water would be disturbed more than any tsunami or hurricane that has been observed during historical times. You have material explosively shooting up and then falling as bolders, rocks and dust/ashes – there would be molten material and jets of hot gasses shooting up that would destroy anything floating on the flood water above so the Ark would be hit with things shooting up and things falling. There would be violent crosscurrents of wind. The air would likely be full of particles (and in some places, super heated) – no creature could breathe this and survive. How hot would the water be? In some places the water would be very hot. There would be heat and shock waves throughout the water. The water would soon be full of ash particles. What would the salinity of the water be like, with the introduction of all of this flood water? Could any marine life survive assuming these conditions existed worldwide for 40 days? What would this do to plant life, from seaweed to the seeds of plants and trees? I don’t see how even a sturdy ship could survive this, or how any person, animal or sea creature or many plants could live through this.
