i) Which of the following is NOT true of energy radiated by the sun? Select one: it is referred to as "shortwave" radiation because the wavelengths are very small it is much more intense than "longwave" radiation it is emitted at a range of wavelengths characteristic of its temperature most of it is trapped by greenhouse gases as it enters the atmosphere
i) Which of the following is NOT true of energy radiated by the sun?
it is referred to as "shortwave" radiation because the wavelengths are very small
it is much more intense than "longwave" radiation
it is emitted at a range of wavelengths characteristic of its temperature
most of it is trapped by greenhouse gases as it enters the atmosphere
II)
For Earth's temperature to remain stable over long periods of time, incoming energy and outgoing energy have to be equal. In other words, the energy budget at the top of the atmosphere must balance. This state of balance is called radiative equilibrium.
Is the incoming energy in balance with the outgoing energy?
Select one:
No, the outgoing energy is greater than the incoming energy
Yes, incoming and outgoing energy are in balance
No, the outgoing energy is less than the incoming energy
iii ) Referring to the answer in the previous question, what do you think the implications might be?
no implications
this is such a negligible amount of radiation that it will not make much difference to the radiation balance.
more energy will build up in the earth system, leading to heating
less energy will build up in the earth system. This if fortunate because it counteracts global heating to some extent.
