Answer:
C) Both are waves of energy, but ultraviolet waves cannot be seen.
Explanation:
Both visible light and ultraviolet are two manifestations of the same thing: electromagnetic radiation (which is, basically, energy in one of its forms). They both travel empty space as waves, but visible light has a longer wavelength, which means that the distance between succesive peaks of the wave is larger than that of ultraviolet radiation. Visible light just happens to have a wavelength in the range our eyes are capable of seeing, but ultraviolet has a shorter wavelength than that, therefore we cannot see it.
Answer:
A line of thunderstorms in the provides moisture and nitrogen to the crops. The energy in the lightning breaks the N2 molecules apart so they can combine with the oxygen to make nitrogen oxides that can be dissolved in the rain. These forms of nitrogen are essential nutrients for plants. Rain from these storms provide far more to the crops than an equal amount of irrigation can do.
