A. When the storm is far distant, the thunder sounds like a deep growl.
Q. Does not scenery affect the sound of thunder?
A. Yes; the flatter the country, the more unbroken the peal: Mountain scenery breaks the peal, and makes it harsh and irregular.
Q. What is the cause of rolling thunder?
A. The rolling is produced by the reverberation of the thunder along the massive clouds.
Q. What is meant by the reverberation?
A. The echo.
Q. Why is a flash of lightning generally followed by a pouring rain?
A. The cloud collapses, as soon as the electric fluid has left it; and the water it contained is squeezed out.
