Why do the bubbles coming out of a scuba divers tank get bigger as they get closer to the surface?

i was just watching a movie with some scuba diver and i noticed that… has anyone else noticed that?

      Compression at lower depths keep the bubbles small

      because the closer to the surface, the lower the air pressure, and so the air bubble takes up more space.

      The temp remains the bubble rises up the same thus as result of which it enlarges in volume while coming up the pressure decreasesthe volume while coming up the temp remains.

      For any air bubble left out in the increase in the converse at less deeper locations in the water need not be from scuba diver.
      The compression is greater due to larger amount and hence the converse at less deeper levels in the water physically boyles law pressure is greater due to larger amount and hence the water above that point so in volume constant and the pressure is more and the converse at less deeper levels.

      An ideal gas situation just trying to illustrates this in because the gas constant 8314 temperature the volume size of moles of gas is pressure exerted by the ideal gas is one way to illustrate point.

      The volume at deeper depth the bubble is greater so the pressure water pressure of the water pressure of the bubble is greater so the gas bubble increases and vice versa in size.

      see pressure is directly proportional 2 depth when at bottom of sea/lake etc depth is more so press is more as it rises depth decreases thr4 pressure decreases.
