Explain the advantages of being neutrally buoyant when you are a scuba diver.?
You do not float to the surface nor do you sink- you stay at the level you swim to.
Why do the bubbles exhaled by a scuba diver grow as they aproach the surface of the ocean?
as the bubbles get closer to the surface, there is less water pressure on them therefore allowing them to expand.
How do divers float after sinking?
Scuba divers can hover at depths with proper buoyancy control. This is achieved when the diver wears the appropriate amount of lead weight to make them sink and has an equalized amount of air inside the buoyancy control device (BCD) to balance the sinking effect with air pressure in the bladder of the BCD & the divers lungs. When proper buoyance is achieved the diver can hover at depth and seem weightless while only moving slightly up or down in the water due to the controlled amount of air within their lungs all while still breathing appropriately at the given depth.
What is the pressure of ocean water at sea level?
Right at the surface of the ocean, the pressure is just the same as the air pressure at sea level; that is, one "atmosphere", or about 14.7 PSI (Pounds per Square Inch). But water pressure increases with increasing depth: For each foot of depth, the water pressure increases by 0.445 PSI. SCUBA divers, who need to be very aware their depth because of this pressure effect, often use this rule: Every 33 feet of depth, water pressure increases by one "atmosphere" (14.7 PSI). So, for example, at 66 feet the pressure on a diver is three atmospheres: There's one atmosphere of pressure from the air, and two atmospheres from the water.
What is the focal length of goggles?
Goggles purchased "off the shelf" should not be refractive, i.e. should not have a 'focal length'. I suppose if you're a die-hard compulsive SCUBA diver, you could buy prescription goggles; then their focal length would be whatever suits your prescription. But for anything bought in a sports supply, if it has a focal length, then you're on the road to eye-strain ... take it back !
Do scuba diver have back bones?
A scuba diver is a human who enjoys scuba diving. Therefore, a scuba diver has a spine and is a vertebrate.

Why would a scuba diver go underwater?
Becasue if a SCUBA diver didn't go underwater, they really wouldn't be a SCUBA diver. SCUBA stands for Self-Contained Underwater Breathing Apparatus.
