1. If you see lightning bolt in the distance and 15 seconds elapse before you hear the corresponding thunder, how far away was the lightning bolt? Give the distance in meters and miles. The speed of sound is 340 m/s. Light travels so fast that you can assume a zero-time interval between the occurrence of the lightning and its sight. 1 mile=1,609 meters.
2) How could updrafts and downdrafts contribute to cloud droplet or ice crystal growth?
