Noah’s Flood: Where Did All the Water Come From?
Bible-believing geologists typically hold the view that most mountain ranges were “pushed up” during the final stages of the Flood (see Genesis 8-9 and Psalm 104). This means that the Flood did not need to cover today’s tall peaks. Currently the total volume of water on the planet is estimated at 1.386 billion cubic kilometers. If we layer it on a smooth sphere it would be a layer with a radius of about 6,500 kilometers, subtracting from here and you get a depth of 2.61 km average. Without today’s high mountain ranges that were created during the Flood, plenty of water (now in the oceans) could cover the world’s land. That’s why 75% of the continents are filled with sedimentary layers that average about 1 mile deep.
