Final answer:
The methods used to protect from overexposure to the sun include wearing sunscreen with SPF, wearing hats, and seeking shade. These are important to prevent skin damage and reduce the risk of skin cancer.
Step-by-step explanation:
Meg, Sandy, Chang, and Nathon may have used various methods to protect themselves from overexposure to the sun, including wearing sunscreen, wearing hats, and seeking shade. The correct answer is 4) All of the above. Sunscreen is essential as it blocks UV radiation and has a sun protection factor (SPF), indicating the level of protection against UVB radiation. Sun protective clothing can also provide protection, with a UPF rating to indicate how effectively it shields against UVA and UVB rays. Overexposure to the sun poses risks such as skin damage and increases the risk of skin cancer, hence the importance of these protective methods.
