Final answer:
True, burns can indeed be caused by UV light rays. UV radiation, particularly UV-B and UV-C rays, can lead to sunburn and increase the risk of developing skin cancer. Though a tan may appear healthy, it is a sign of underlying skin damage.
Step-by-step explanation:
The statement that burns can be caused by UV light rays is true. Exposure to UV light, including both UV-B and UV-C rays, can result in sunburn. Sunburn is a form of skin damage that occurs when the skin is exposed to large amounts of UV radiation, leading to the outer layer of the skin being damaged.
Additionally, overexposure to UV light can accelerate the aging of the skin, causing wrinkles, and increase the risk of skin cancer. This risk is heightened if a person experiences significant sunburns, especially during childhood or adolescence.
While tanning might give a temporary aesthetically pleasing color to the skin, it is a sign of skin damage. A natural defense mechanism kicks in where the body produces more pigment in an effort to protect the skin from further UV damage.
