Why should extra precautions against sun exposure be taken when boating? (5 points) 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.

D. The water reflects U.V rays, adding to exposure.

Explanation:

This is true because water reflects light, which contains UV. When UV is reflected it is magnified by 25%.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
