Answer 2

water

Question 3

3 characteristics of water

Answer 3

include buoyancy, hydrostatic pressure, and enhanced cooling.

Question 4

is the upward force of the water on an object. This is the reason why boats and people
float on water. It also gives a weightlessness feeling, which makes it easier to move, lift knees
or even jog in water (for some water activities).

Answer 4

Buoyancy

Question 5

the pressure exerted by the water at equilibrium due
to the force of gravity. In other words, it is the weight of the water pressed down on the object.

Answer 5

Hydrostatic pressure,

Question 6

is exerted on the body from all sides and this pressure, combined with
buoyancy, helps keeps standing balance in water. Water, therefore, helps people who have problems
with balance and coordination.

Answer 6

Hydrostatic pressure

characteristic that transfers heat away from the
body much quickly than air given in the same temperature. This is the reason we can stay longer
in water and can tolerate longer workouts without feeling being overheated.

Benefits of Snorkeling

Answer 56

Snorkeling helps the overall fitness of a person. Aside from having fun under the water swimming, doing the flutter kick and diving tones and trims the body. It works out the quadriceps, hamstring, calves, ankles, hip, flexors, core muscles, and shoulders while swimming. Above all, snorkeling builds greater lung capacity as one is forced to hold breath underwater for sustained periods of time. It increases the oxygen uptake, which is a positive indicator of aerobic fitness. It is also a good cardiovascular workout as it increases heart rate and strengthens the heart muscle.
