2. in the winter, weather reporters often day "it will be a very cold night because there are no clouds." a. use the sim to see if you can understand why this could be true. b. describe your observations. c. would there be a difference between daytime and nighttime cloud effects

a. Clouds at night prevent the heat radiation of the earth from escaping back into the space by continuously reflecting them back.

b. If during the day the earth has been heated well by the sun and then if the night is cloudy then that night is not so cold.

c. Day time clouds prevent the heating of the earth by reflecting back the radiations of the sun back into the space.

Explanation:

During the day if there is sunshine and then if the night is cloudy then that night will not be so cold because during the day the earth has absorbed the heat of sun's radiation which it radiates at night but when there is cloud at night it acts as a reflecting screen and reflects the heat radiations back to the earth.

But  if there is cloud during the day time it prevents the radiations from the sun to fall on the earth by reflecting them back into the space preventing the rise in temperature of the earth.
