In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. Genesis 7:11
"...Pilbara craton in Australia and Kaapvaal craton in South Africa suggest the Earth experienced a period of intense bombardment (Archean Eon), roughly the same time the first indications of plate tectonics appear in the rock record.
“Modeling studies of the earliest Earth suggest that very large impacts — more than 186 miles in diameter — could generate a significant thermal anomaly in the mantle,” Dr. O’Neill said.
“This appears to have altered the mantle’s buoyancy enough to create upwellings that could directly drive tectonics.”
“Our work shows there is a physical link between impact history and tectonic response at around the time when plate tectonics was suggested to have started,” he said.
“Processes that are fairly marginal today — such as impacting, or, to a lesser extent, volcanism — actively drove tectonic systems on the early Earth."
