The top five gasses found in normal (atmospheric) air by

volume are:

• A.

Nitrogen, Oxygen, Carbon Monoxide, Hydrogen, Helium

• B.

Carbon Monoxide, Nitrogen, Oxygen, Xenon, Water Vapor

• C.

Nitrogen, Oxygen, Argon, Carbon Dioxide, Neon

• D.

Oxygen, Nitrogen, Carbon Dioxide, Helium, Radon Correct Answer

• Nitrogen, Oxygen, Argon, Carbon Dioxide, Neon 1 / 4

Explanation The correct answer is Nitrogen, Oxygen, Argon, Carbon Dioxide, Neon.These five gases are found in normal atmospheric air in varying volumes.Nitrogen is the most abundant gas, making up about 78% of the air.Oxygen is the second most abundant gas, comprising about 21%. Argon is present in trace amounts, around 0.93%. Carbon Dioxide is a greenhouse gas and is present in very small amounts, around 0.04%.Neon is an inert gas and is found in even smaller quantities.

The primary factors determining your air consumption rate are:

• A.

Depth, Total Nitrogen Time, and fin size

• B.

Age, currents, and visibility

• 3 / 4

Water temperature, Residual Nitrogen Time, physical fitness of diver

• D.

Depth, physical activity, and water temperature Correct Answer

• Depth, physical activity, and water temperature

Explanation The primary factors that determine your air consumption rate while diving are depth, physical activity, and water temperature. Depth affects the pressure on your body, which in turn affects your breathing rate. Physical activity increases your breathing rate and therefore your air consumption.Water temperature also affects your breathing rate, as colder water can cause your body to work harder to maintain its temperature. These three factors combined have a significant impact on how quickly you consume air while diving.
