liquid pressure increases with depth why
Answers
Answer:
━━━━━━━━━━━━━━━━━━━━━━━━━
Water pressure is the result of the weight of all the water above pushing down on the water below. As you go deeper into a body of water, there is more water above, and therefore a greater weight pushing down. This is the reason water pressure increases with depth.

Explanation:
In water, pressure varies with depth. Less depth means less pressure. Therefore, as you go up in elevation, or height, air pressure decreases. For example, if you were at the top of a high mountain, you would have less air pushing down on you than you would if you were at sea level.
Calculations:
If you are at sea level, each square inch of your surface is subjected to a force of 14.6 pounds. The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level.
Reason:
This is due to an increase in hydro static pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you.
Fun Fact:
Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean's pressure can indeed crush you
