What is buoyancy? - ANSWER-Buoyancy is an upward force produced from a
liquid pushing on an object.
My sunglasses case falls out of my pocket into the water, but fortunately, it floats
so I retrieve it. I would say my sungalsses case is [blank] buoyant. - ANSWER-
Positively
Salt water causes more buoyancy than fresh water because it is less dense and
weighs less. True or false? - ANSWER-False. Salt water causes more buoyancy
because it is more dense and weighs more; buoyancy results from the weight of
the water displaced.
To control my buoyancy, normally I will use my weight system and my [blank] -
ANSWER-BCD
When I descend, my buoyancy tends to [blank]. When I ascend, it tends to
[blank]. - ANSWER-decrease, increase
Underwater, when I inhale, my buoyancy [blank] - ANSWER-increases slightly
It is important to master buoyancy control because it affects almost everything I
do in and underwater. True or false? - ANSWER-True
, As you descend in water the pressure increases, decreases or doesn't change? -
ANSWER-increases
