The model represents the oxygen cycle on Earth. If widespread habitat destruction and urbanization continues, how might we expect this model to change, as represented by flux?

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.

Which type of energy is transferred by convection currents?
