1) Because of already dissolved gases in water. As water is heated, these dissolved gaseous molecules rise up and escape.
2. Because of non-uniform heating. If we heat water using a utensil which supplies heat only from bottom, the water attains an upward-decreasing temperature profile. Which means the water at the bottom is at a higher temperature. This leads 'water at the bottom' to reach boiling point faster than the rest of the water and hence it evaporates early and we can see bubbles in the bottom.

The bubbles are formed or seen when the dissolved gases comes out of the water as the bubbles.
