Answer:
increases
Step-by-step explanation:
The terrific pressures are some of the most formidable obstacles in carrying out deep-sea exploration. Imagine a block of wood 6" x 6" x 6", or 216 cubic inches in volume. At a depth of 3,000 feet, the block would be squeezed to one-half its volume, or 108 cubic inches. Its density would then be such that it would sink to the bottom. The pressure at the deepest part of the ocean is about 14,000 pounds per square inch, almost 1,000 times the atmospheric pressure at the earth's surface (14.7 pounds per square inch).
