Question:
Why is it that sometimes on a clear day you can hear radio stations that are far away?


Replies:
When the temperatures are right, with the atmosphere forming definite layers of gases with smooth boundaries between the layers, radio waves can reflect off these boundaries, bouncing back toward the earth. This gives the radio waves the ability to travel much farther before having to travel out into space.
