What is the primary purpose of a scuba diving mask?

  1. To protect the eyes from water pressure.

  2. To provide clear underwater vision.

  3. To regulate breathing underwater.

  4. To keep the diver's head above water.


Correct Option: B
Explanation:

A scuba diving mask is designed to provide clear underwater vision by creating an air-filled space in front of the eyes, allowing the diver to see clearly while submerged.

What is the function of a scuba diving regulator?

  1. To control the flow of air to the diver.

  2. To measure the depth of the dive.

  3. To provide buoyancy to the diver.

  4. To communicate with other divers underwater.


Correct Option: A
Explanation:

A scuba diving regulator is a device that controls the flow of air from the scuba tank to the diver's mouth, ensuring that the diver receives a continuous supply of breathable air.

What is the purpose of a buoyancy compensator device (BCD) in scuba diving?

  1. To control the diver's buoyancy underwater.

  2. To provide warmth to the diver.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: A
Explanation:

A buoyancy compensator device (BCD) is a vest-like equipment worn by scuba divers that allows them to control their buoyancy underwater by adjusting the amount of air in the device.

What is the function of a scuba diving tank?

  1. To store compressed air for breathing underwater.

  2. To provide buoyancy to the diver.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: A
Explanation:

A scuba diving tank is a cylindrical container that stores compressed air or other breathing gases for use by scuba divers underwater.

What is the purpose of a scuba diving computer?

  1. To monitor the diver's depth, time, and air pressure.

  2. To provide warmth to the diver.

  3. To measure the distance traveled underwater.

  4. To communicate with other divers underwater.


Correct Option: A
Explanation:

A scuba diving computer is a device worn by scuba divers that provides information about the diver's depth, time spent underwater, and remaining air pressure in the tank.

What is the function of a scuba diving weight belt?

  1. To provide buoyancy to the diver.

  2. To keep the diver's head above water.

  3. To control the diver's buoyancy underwater.

  4. To add weight to the diver for better underwater stability.


Correct Option: D
Explanation:

A scuba diving weight belt is worn by divers to add weight to their bodies, helping them to achieve neutral buoyancy and maintain stability underwater.

What is the purpose of a scuba diving dive light?

  1. To provide warmth to the diver.

  2. To illuminate underwater environments.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: B
Explanation:

A scuba diving dive light is a portable light source used by divers to illuminate underwater environments, allowing them to see clearly in low-light conditions.

What is the function of a scuba diving snorkel?

  1. To provide warmth to the diver.

  2. To breathe underwater.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: B
Explanation:

A scuba diving snorkel is a tube that allows a diver to breathe underwater by taking in air from the surface while the diver's face is submerged.

What is the purpose of a scuba diving fins?

  1. To provide warmth to the diver.

  2. To propel the diver through the water.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: B
Explanation:

Scuba diving fins are worn on the diver's feet to propel them through the water, allowing for efficient movement and maneuverability underwater.

What is the function of a scuba diving dive knife?

  1. To provide warmth to the diver.

  2. To cut through underwater obstacles.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: B
Explanation:

A scuba diving dive knife is a small, sharp knife carried by divers for various purposes, including cutting through underwater obstacles, lines, or entanglements.

What is the purpose of a scuba diving compass?

  1. To provide warmth to the diver.

  2. To navigate underwater.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: B
Explanation:

A scuba diving compass is a navigational tool used by divers to determine their direction underwater, helping them to navigate and stay on course during their dive.

What is the function of a scuba diving surface marker buoy (SMB)?

  1. To provide warmth to the diver.

  2. To signal the diver's location on the surface.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: B
Explanation:

A scuba diving surface marker buoy (SMB) is a brightly colored inflatable buoy that is deployed by divers to signal their location on the surface to boat crews or other divers.

What is the purpose of a scuba diving underwater communication device?

  1. To provide warmth to the diver.

  2. To communicate with other divers underwater.

  3. To measure the depth of the dive.

  4. To signal the diver's location on the surface.


Correct Option: B
Explanation:

A scuba diving underwater communication device allows divers to communicate with each other underwater, either through hand signals, underwater slates, or electronic devices.

What is the function of a scuba diving first aid kit?

  1. To provide warmth to the diver.

  2. To treat minor injuries underwater.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: B
Explanation:

A scuba diving first aid kit contains essential medical supplies and equipment for treating minor injuries that may occur during a dive.

What is the purpose of a scuba diving logbook?

  1. To provide warmth to the diver.

  2. To record dive information for future reference.

  3. To measure the depth of the dive.

  4. To communicate with other divers underwater.


Correct Option: B
Explanation:

A scuba diving logbook is used to record dive information such as date, location, depth, time, and any notable observations or experiences during the dive.
