3.) What is the special feature that allows a submarine to go underwater and come back up?
A.) Wings
B.) Periscope
C.) Ballast tanks
D.) Lights

4.) What is a periscope on a submarine used for?
A.) Taking underwater photos
B.) Seeing above the water’s surface
C.) Collecting water samples
D.) Playing music

5.) What do submarines use to communicate underwater?
A.) Telephones
B.) Radio waves
C.) Sonar
D.) Loudspeakers

10.) What is the job of a periscope operator on a submarine?
A.) Cook meals for the crew
B.) Fix broken engines
C.) Navigate and see above water
D.) Play video games
Answer: C.) Navigate and see above water
Explanation: The periscope operator’s job is to use the periscope to navigate and see what’s happening above the water without the submarine surfacing.
11.) Why do submarines have sonar equipment?
A.) To listen to music
B.) To navigate and communicate underwater
C.) To make loud noises
D.) To scare away fish
Answer: B.) To navigate and communicate underwater

12.) What is the purpose of ballast tanks on a submarine?
A.) To store food
B.) To make the submarine float
C.) To control depth by filling with water
D.) To carry toys for entertainment
Answer: C.) To control depth by filling with water

A.) Underwater radio
B.) Submarine talkies
C.) Sonar
D.) Ocean chat
Answer: C.) Sonar

14.) What do submarines use to avoid being heard by other ships or creatures underwater?
A.) Whistles
B.) Silence mode
C.) Special underwater lights
D.) Stealth technology
Answer: D.) Stealth technology
Explanation: Submarines use stealth technology to move quietly underwater and avoid being heard by other ships or creatures. It’s like being invisible.
