Answer: 18 metres/60 feet
2. As you descend in water, the pressure
Answer: increases
3. A depth change of 10 metres/33 feet causes a pressure change of
Answer: 1 bar/ata (atmosphere)
4. if you take 6 liters of air from the surface to 20 metres/66 feet, the volume will be
Answer: 2 litres (the density of the air would be three times the density at the surface)
5. A balloon fully inflated and sealed at 10 metres/33 feet, would probably
during ascent to the surface
Answer: burst

suitability, fit, and
Answer: comfort
16. The two basic fin styles are fins
Answer: adjustable and full-foot
17. My primary considerations when choosing fins are fit and
Answer: blade size
18. BCD (buoyancy control device)
Answer: holds your kit together and allows you to adjust buoyancy through- out the dive
