A closer look at our Creator’s work in nature.


If you pushed a glass ball to the bottom of the ocean, would it be crushed? 
--Josh M., age 8
 
The simple answer is yes. That is because water pressure at the bottom of the ocean is much greater than the air pressure inside the ball. As the ball descended to the depths, the air inside the ball would get squeezed, or compressed. As the air shrunk, the glass would collapse to fill the space that the air once filled. The glass ball would implode, which is the opposite of “explode.” This can happen to any air-filled container that goes too deep. In fact, malfunctioning submarines have imploded.

Pressure increases the deeper you go. There is a limit to how far people can dive and how deep man-made equipment can go because of this increasing pressure. Yet all kinds of creatures withstand the effects of crushing pressure and thrive in the deepest parts of the sea.

God’s Fingerprint in Creation
Picture this. Somewhere out in the Pacific Ocean, a 98-foot-long (30-meters-long) blue whale rests in the sunshine just below the water’s surface. It slaps its tail and dives more than 325 feet (100 meters) to the dark waters below. If the whale were a building, its tail would be at the tenth story, while its head is in the lobby. The weight of water on the whale’s head is much, much greater than the water pressure on its tail. The contents of the whale’s head and chest ought to shoot up into its tail to equalize the pressure. Gross thought! God’s design ensures this doesn’t happen.

Sperm whales dive several times deeper than blue whales to catch their favorite seafood meal of squid. They routinely hunt squid at 1,600-3,200 feet (500- 1,000 meters) and have been found below 6,000 feet (2,000 meters). At these depths, water pressure makes the rib cage fold up and their lungs collapse. The air empties out of the lungs, but the whale doesn’t die. Deep-diving whales undergo many other death-defying changes that boggle scientific minds.

The Challenger Deep is the deepest known part of the ocean at 6.78 miles (10.91 kilometers) or below the surface. Read Micah 7:19 to find out what the Bible says about what’s down there (metaphorically speaking).
