The sun radiates energy. does the earth similarly radiate energy? if so, why can’t we see the radiant energy from the earth?
1. yes, the earth radiates energy, but only in the sense that the energy is reflected sunlight, which we can’t see from the earth’s surface.
2. no, the earth does not similarly radiate energy.
3. yes, the earth radiates energy, but since the peak frequency f is directly proportional to the absolute temperature of the radiator, the wavelength of the radiation is far too long for us to see.
4. yes, the earth radiates energy, but since the peak frequency f is directly proportional to the temperature of the radiator in degrees kelvin, the frequency of the radiation from the earth is in the ultraviolet range (so that.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
