56. METEORS 



These are very small bodies of matter, or combinations of 

 small bodies, revolving around the sun like the planets. They 

 are cold, and not large enough to reflect sufficient light to be 

 seen, and therefore they are invisible until they suddenly 

 flash into our atmosphere. The light is produced by the in- 

 tense heat due to friction against our atmosphere. The large 

 majority of meteors are entirely consumed, or dissipated into 

 dust, before they reach the earth. A huge number of meteors 

 fall every year, and it has been estimated that they add about 

 forty thousand tons of weight to the earth each year. As 

 they fall to the earth they move at about twenty-six miles a 

 second, and their fall may be accompanied by a roaring noise 

 and often ends in an explosion. Their composition is mostly 

 stone, although some have been found composed practically 

 of pure iron.
