Why are cameras / camcorders waterproof to certain depth?

[jamesmiller88]

This just came up in my mind, How come cameras / camcorders are waterproof only to a certain depth. Like the Kodak play sport, it says it's waterproof only down to 10 feet or something. What happens if you go lower?
Force Factor

well it is because of the pressure.. the more deeper your camera will be the more pressure will be applied on it due to water..
