Which of the following is NOT a type of wave?

• A. Surging
• B. Spilling
• C. Frothing
• D. Plunging

Answer: (C)

The correct answer is frothing, as it is not classified as a type of wave. Waves are typically categorized based on their behavior as they break on the shore. Surging waves are characterized by their tendency to rush up the shore without breaking, while spilling waves gradually break over a wide area, creating a gentle flow. Plunging waves, on the other hand, are known for their fast and dramatic breaking, creating a well-defined, steep-face wave. Frothing, while it describes a visual aspect of waves where the water appears foamy or bubbly, does not specifically refer to a recognized wave type in oceanography or surf lifeguard terminology. Recognizing the different categorized waves helps lifeguards understand the surf conditions, enabling them to make informed decisions about safety and rescue operations.
