The Grand Canyon, rightfully considered a national wonder, is 277 miles long, up to eighteen miles wide, and more than 5000 feet deep. However, scientists have discovered one submarine canyon that is three times deeper than the Grand Canyon and another one that is ten times longer. Submarine canyons—great oceanic canyons—practically encircle the earth. Some of these huge trenches measure almost eight miles beneath the ocean floor.
The Mid-Oceanic Ridge was discovered by map pioneers Bruce Heezen and Marie Tharp in the 1950s. The Bible contends that before the Flood, the earth was one landmass. As the crack encircled the earth, it caused the great continental plates to move away from each other, forming the various continents. Many say the science of plate tectonics reflects this.
At the time of the Flood, it is believed that sixty- to ninety-mile jets of hot water burst through the ocean floor (“the fountains of the deep”). The jets caused a microscopic crack in the ocean floor to split open. Both ends of the split zipped around the earth at the incredible rate of about three miles per second—circling the globe in less than two hours. When one end of the crack slammed into the path left by the other end, beneath the Indian Ocean, a 40,000-mile Y-shaped mountain range was formed.
