      Hi annoying1hoot
      Pressure is a measure of force per unit area.
      The deeper into water you go, the more pressure there will be from all the water above you. And since water is much heavier than air it puts a lot of pressure on your lungs and can cause decompression sickness, something that is common in deep sea divers.
