Quiz Answer Key and Fun Facts

1. What does the acronym SCUBA stand for?

Answer: Self Contained Underwater Breathing Apparatus

Back in the 40's and 50's this came around to help us discover our underwater world.

2. Which 3 major air spaces are most affected while descending?

Answer: Sinuses, ears, mask

The tiny air spaces in your ears and sinuses are affected along with the air pocket from your mask. Equalize early and often.

3. What two metals are scuba tanks commonly made from?

Answer: Aluminum and steel

These two metals are strong enough to contain the air pressure at high PSI inside rather than rupture and explode.

4. Which part of the regulator do you breathe from?

Answer: Second Stage

First stage hooks to your tank, purge valve helps clear water out of the hose, and the hose of course, carries your air.

5. How many feet does the pressure increase by 1 bar?

Answer: 33 feet

For every 33 feet, the pressure increases by 1 bar.

6. Underwater, objects are magnified by about how much?

Answer: 33 percent

Things tend to be 33 percent larger and appear 25 percent closer while looking at them underwater due to light refraction phenomena, so the fish you see while scuba diving look a lot bigger.

7. While diving in cold water, you should wear a hood because you lose as much as ______ percent of body heat from your head, according to many dive books and instructors.

Answer: 75

Also in the summer, it can actually keep you cooler.

8. When diving, many divers are visited by the aquatic life. Nearly all injuries to divers result from what?

Answer: Diver carelessness

Most divers are attacked because they provoked it. Scuba usually is a safe trip with our aquatic friends.

9. In order, what are the terms for front of boat, right side, bathroom, and left side of boat?

Answer: Bow, starboard, head, port

This is useful information so when approaching a boat from below, the divers are aware of which side of the boat is which.

10. An item you really should have a backup of in case it breaks while diving is what?

Answer: All of these
