As the sun was shining on the sea, it reminded rayson about the water cycle of the earth. from his secondary school years, he remembered that the sun is responsible for sustaining rainfall on the planet by evaporating water. using the solar flux, help rayson determine the average global annual rainfall in mm/yr! multiply your answer by 0.05 to account for the fact that not all sunlight reaches the earth evenly and at once, due to the earth’s rotation and atmosphere. also, give your estimate in 2 s.f. (solar flux = 1373wm⁻² , latent heat of vaporization of water = 2260000 jkg⁻¹ , latent heat of fusion of water = 334000 jkg⁻¹ , density of water = 1000 kgm⁻³ )
