Why do my ears pop when I dive in the deep end of the pool?

When you swim in deep water or deep part of the pool, there can be a lot of water pressure. At sea level, the air's pressure is 14.7 pounds per square inch (PSI). Each foot of water creates water pressure of 0.43 PSI. So if you swim in 10 feet of water, the total water pressure is 4.3 PSI. Add that to the air pressure of 14.7 and the total pressure at the bottom of the deep end is 19 PSI. in short the reason why you your ears seems to pop is because of the water pressure the deeper you go the higher the water pressure becomes. The same sort of pressure difference can arise as you go up or down in a tall building on a fast elevator, or as you ascend or descend in a small plane. To solve the problem, you can equalize the pressure. When you start to feel pain in your ears, hold your nose shut with your fingers and blow into your nose.

maybe u made a wrong dive thats whyt it pop up your ears

Its pressure. underwater the deeper you go the more pressure it is, so your ears are trying to equalize so your ear drums don't burst.

Because of the pressure. The pressure is getting higher the deeper you go. There are people that resist to bigger pressure and people who don't.

you have to plug ur nose and breath with ur mouth closed to pop ur ears out so the pressure of the water does not pressure your head into feeling like it's caving in. we learned that in science because we are going to be going scuba diving in march
