Because the water near heating element turns to water vapor. This vapor tries to rise up to the surface but as it meets colder water upwards it turns back into water. As the water/steam transition is not smooth (e.g. the volume changes rather rapidly during phase change), the constant transition between vapor and liquid states produces noise. As the water gets to +100C (boiling point), the vapor bubble will not turn back into liquid before reaching the surface thus making less noise.

It is due to a build-up of limescale on the boiler's heat exchanger. This traps steam bubbles that expand and explode, causing the noise. You need to descale the boiler's heat exchanger to cure the noise.

Depending where the noise was coming from, but this question is most likely to be answered in this way. If you switched a valve off and the noise was coming before the valve in the pipes, that would indicate a burst pipe.
