Why should extra precautions against sun exposure be taken when boating? a. water cancels out most sunscreens. b. uv rays are blocked over land, but not over water . c. the heat of the water increases potential skin damage. d. the water reflects uv rays, adding to exposure.

The answer is D. The water reflects UV rays, adding to exposure.

Explanation:

Being at sea, there is a direct exposure to sunlight. when the rays reach the marine surface, a mirror effect occurs, thus reflecting the sun, causing an increase in the intensity of the UV rays; also, that the sea breeze, being quite moist, helps moisturize the skin and generates a kind of freshness, distracting the person who is sailing, on the UV radiation that is receiving.
