Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

How would the following be affected in the absence of atmosphere around the earth?
a) Surface temperature of earth.
b) Range of radio waves transmission.
Give brief explanation in support of your answer. ANS- a) The temperature of earth will decrease since the greenhouse effect will not take place in absence of atmosphere.
b) Range of radiowaves will decrease since ionosphere will be absent.
