vocab
This term describes how far below the surface something is.
depth
Divers rarely go straight down because pressure increases too quickly. Instead, they dive at one of these.
they dive at an angle
This is the only angle that’s completely vertical.
90 degrees
The term for moving from the surface to a deeper depth.
decent
What are the things you wear on your feet when diving
flippers
This measures how far apart two points are, usually in a straight line.
distance
Diving at an angle helps protect these two parts of your body.
ears and lungs
If a diver goes 12 meters down and 16 meters across, what geometric concept helps find the total distance traveled
Pythagorean theorem
A straight vertical descent can cause discomfort in this part of the body.
ears
whats is the thing that covers your face to see underwarter
scuba mask/googles
This is the angle at which something moves downward compared to a horizontal surface.
angle decent
The triangle formed by a diver’s path, the ocean floor, and the vertical depth is this type of triangle.
right trangle
Before diving, you must plan how far, how long, and where to stop to avoid this dangerous condition.
lung poisoning or pressure-related injury
Angled descents are smoother and safer because they allow divers to do this gradually.
equalize pressure
Can you just go for a swim by yourself, not knowing how to dive
no
The process of finding your position and moving in the right direction underwater.
navigation
The shortest path a diver swims underwater, combining vertical and horizontal movement, is called this side of a triangle.
hypotenuse
The horizontal distance a diver swims across the ocean floor is measured in this direction.
horizontal direction
Descending at an angle also helps divers reach this kind of underwater destination.
reef or wreck
What is the tank called that gives you air?
air tank
This tool helps divers track their depth, time, and direction underwater.
scuba diving computer
Scuba diving computers usually display both units for this reason.
accommodate all divers?
The choice between meters or feet depends mostly on this factor.
country or location
Divers measure depth in these two units.
meeters and feet
