How can waves affect divers?

1. Enhancing visibility underwater

2. Causing sickness and making movement difficult

3. Preventing entry and exit from the water

4. Both B and C

The correct answer is: Both B and C

Waves can significantly impact divers in a couple of ways. First, they can create conditions that cause motion sickness due to the swaying and turbulence, which can make divers feel nauseated and uncomfortable. This physical discomfort can hinder their ability to focus and perform underwater activities effectively. Furthermore, waves can make it challenging to move through the water, as they can push divers around unpredictably or create resistance, complicating navigation and control. In addition to affecting how divers feel and move, waves can also pose practical challenges regarding water entry and exit. Strong waves can make it dangerous to enter the water, as the force of incoming waves could lead to injuries or accidents. Once underwater, exiting can be equally challenging, as the waves may push divers away from their exit points or make it difficult to get out of the water safely, especially if they are strong or crashing. Together, these factors underscore the importance of understanding wave conditions and their implications for divers, thereby making it clear why the combination of causing sickness and making movement difficult, alongside preventing safe entry and exit, is the correct consideration.
