PADI Open Water Diver Course - Section 1
Training is important because? - accurate answers-It enables diving to be
rewarding and meaningful, there are potential hazards to avoid, reduce
and/or manage and diving has risks.
Certification shows? - accurate answers-Certification shows that you met the
course requirements.
You will be trained to what depth? - accurate answers-A maximum of 18
metres/60 feet.
What conditions are you qualified to dive in? - accurate answers-Conditions as
good as, or better than, those in which you trained.
The three parts of the course are? - accurate answers-Knowledge
development, confined water dives and open water dives.
Knowledge development covers the principles, concepts and terms needed for
safety.
Confined water dives allow practise of scuba skills in a pool under direct
instructor supervision through one or more mini dives.
Open water dives allow practise, application and demonstration of what you
have learnt.
Completing the course allows you to? - accurate answers-Dive without
instructor supervision, obtain air fills, scuba equipment and other dive
services, plan, conduct and log open water dives and continue your diver
training.
,What is the PADI four E philosophy? - accurate answers-Equipment,
education, experience and environment.
Scuba requirements? - accurate answers-Age - you must be at least 10. 10-14
earn the PADI junior diver certification. 10-11 must dive with a PADI
professional and 12-14 must dive with a certified adult diver.
What is Performance-Based learning? - accurate answers-Performance-based
learning means you progress and attain certification by demonstrating that
you meet specific learning objectives.
What is Student-Centered learning? - accurate answers-Student-cantered
learning means that the course, materials and instructor address how you
learn most effectively.
What are 11 reasons to dive? - accurate answers-Adventuring and exploring.
Enjoying and observing nature.
Spending time with friends/family.
Getting out on and under the water.
Taking photos and videos.
Investigating sunken ships.
Taking on personal challenges.
Becoming familiar with new technologies.
Making new friends.
Making a difference in environmental issues.
Enjoying a new world.
, Are you under more pressure underwater, and if so, why? - accurate answers-
You are under more pressure underwater as water also has weight, which
combines with the weight of the atmosphere. Water is much fender and
heavier.
What is the pressure increase for each 10 metres/33 feet you descent? -
accurate answers-The pressure increases by one bar/ata. Likewise, it
decreases by one bar/ata for every 10 metres/33 feet you ascend.
What does pressure change effect? - accurate answers-Pressure changes effect
the volume and density of air. As you go deeper, the pressure increases and so
a gas volume decreases and gas density increases. This effects all air spaces in
direct contact with your body.
How do air volume and density change with pressure? - accurate answers-Air
volume and density change proportionately with pressure. As you go from the
surface to 10 metres/33 feet, the pressure doubles to 2 bar/ata. The air
density is x2. From 10 metres/33 feet to 20 metres/66 feet, the pressure is 3
bar/ata (1 air plus 2 water). The air density is x3.
What are the three major body air spaces effected during descent? - accurate
answers-Ears, sinuses and mask.
What is a squeeze? - accurate answers-A squeeze causes discomfort and, if not
corrected, can cause injury by pressure imbalance that pushes tissue into an
air space as there is greater pressure outside the air space than within.
What is equalization? - accurate answers-Equalization keeps the pressure
equal with the outside pressure so that they stay at their normal volume. This
is done by adding air to air spaces during descent.
