SNORKELING
Snorkeling is a great way to see
life under water. You float on the top of the water and breathe through a
snorkel. One end of the snorkel tube fits in your mouth, and the other end
sticks above the water. But you must be a good swimmer to do the snorkeling.
Because snorkeling only requires
basic equipment, most people find it easier to take up than scuba diving, which
requires specialized equipment and training. The two activities differ in that
snorkelers do not take air tanks underwater with them to enable them to
breathe. Instead, snorkelers hold their breathe while underwater and breathe
only while at the surface.
The
primary swimming technique used by snorkelers is the free dive, also called a
breathe-hold dive. To make a free dive, snorkelers take a deep breath of air
through the snorkel, bend their bodies down at the waist, and kick their feet
up. This action forces their bodies underwater, and they can descend in a straight
line.
Once the diver begins to run out of
breath, he or she swims back up to the surface. By exhaling, or blowing
strongly, the diver clears water that has entered the snorkel tube during the
dive. The diver can then take another breath through the snorkel and resume
floating at the surface without lifting a head above water.
Without a snorkel, the diver would
bob up and down on the surface and be hit by waves while struggling to breathe,
in addition, the diver might lost sight of underwater objects of interest. By using
a snorkel and remaining face down, the diver can easily float over the waves
while continuing to breathe and maintaining focus on underwater objects.
Thanks for reading :D
