By putting additional air in the buoyancy compensator (BC) vest.
For shallow dives in cold climates, they are to keep the diver warm. For deep dives, they are to protect the diver from the cold and high pressure and to provide a supply of oxygen.

Surface, shallow-water, deep-water and saturation dives in SCUBA - to name a few.
In the Olympics, a 'gainer' refers to a type of diving. 'Gainer' dives are also known as 'reverse' dives, and involve the diver performing somersaults in the air while diving.
Gas loading needs to be considered after diving before complete outgassing has occurred in any future dives, airplane travel with cabin pressures below 1atm, or in any case where the diver's altitude may change to the point that air pressure is significantly reduced below 1atm. (So no mountain climbing until you're clear!).
It depends on how deep the diver goes, and what air blend the diver is breathing. There are dive tables that state how long a diver can stay at a certain depth before requiring decompression. The basic recreational diver typically breathes either air or Nitrox. There are separate dives tables for air and Nitrox.
Diving is scored on a scale of one to ten with ten being the best. three judges score the diver. after all of the dives are completed, the diver's scores are added up and compared with the other athletes.
diver's short name or code for your 'average' dive trip on a dive boat - 2 dives, each separated by an approximate 1 hour SIT (Surface Interval Time), usually on 2 different dive spots.

A diving block is a mental block the stops the diver from being able to do a certain aspect of diving such as the hurdle or twisting dives or most common are reverse dives. this happens in many other sports to such as pole-vaulting or gymnastics.
No such thing.. it depends what you want to see, what your abilities are, who you are diving with, I taught a diver trained him to 40 metres, and now he paints fish, and dives in a river at the back of his garden at 2 metres!!
Many dive shops offer a two day program for the classroom and pool sessions, followed by a four dives done over two additional days. So the short answer is that you can become a certified scuba diver in four (sometimes less) days. How many years does it take to become a GOOD scuba diver, I'll leave for someone else to answer. Like anything, a good teacher and plenty of practice can bring you safely to that goal.
There are many definitions of surface diving. The most common is to go from the surface and dive to the bottom. Some people think it is different.
It depends on your experience. The limit for recreational diving is 130 feet. However, a novice diver should not be diving near that depth. According to PADI, dives deeper than 60 feet are considered deep dives.
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
This question is a little vague. To answer in the simplest terms...swim to the surface at a rate of no more than one foot per second. After long dives or deep depths, divers should make a safety stop for several minutes before finally breaking the surface to be certain that the necessary amount of excess nitrogen has been expelled from the body.
The only precautions are the same ones to take when diving on air. Helium is not the scary gas it has been made out to be. Usually the time limits will be reduced when diving with some helium in your gas for a "trimix" (oxygen, nitrogen, and helium) so the underwater time will need to be planned as with all dives. A diver must also have good control over their ascent and ascend slowly such as 9 meters/30 feet per minute as well as doing good safety stops. But again this should be done with all dives. The only time helium is a problem is when a diver cannot control their ascent and will just "pop" to the surface or a diver does not plan the reduced underwater time that results when using helium - although sometimes the time is not reduced ... it just depends on the exact blend of the gas being used.
Dives are catagorized in the following ways. Forwards the diver faces forwards towards the water at the start of the dive and rotates in that direction. backwards the diver faces away from the water at the start of the dive and rotates backwards towards the water reverse the diver faces forwards towards the water at the start of the dive and rotates backwards after tajke off. Inwards the diver faces away from the water at the start of the dive and rotates farwards towards the board after take off Twisting Any dive that involves a twist so you can have any of the above dives with an added twist handstand a dive off the platform 5metres 7 metres or ten metres that starts in a hand stand position.

Wetsuits are typically made out of an insulating, rubber-like substance called neoprene and they are designed to fit snuggly (but not too tight). When a diver first jumps into the ocean, a small amount of water will seep in and form a layer of water between the diver's skin and the neoprene wetsuit. The diver's body will warm that water to nearly body-temperature. Because the wetsuit fits snuggly, that water does not circulate with the ocean water, it stays against the skin forming a warm insulating layer between the diver and the ocean. It should be noted that wetsuits are not appropriate for diving in all climates as they will only keep a diver so warm. Another kind of suit called a Dry Suit is worn for dives in very cold water, and these suits are much warmer. The use of dry suits requires additional training, however, to learn how to handle the additional buoyancy of the air in the suit.
