2.  Lightning is an enormous electrostatic discharge between clouds and the ground, other clouds, or within a cloud.  Negative charges form towards the base of a cloud while positive charges form at the crown.  The same happens in the ground or other clouds. Physics 1010

3.  Ground to Cloud  Most typical  Clouds form negative charge at base  Ground form positive charge to balance out Physics 1010

4.  Cloud to Cloud  Similar to Ground to cloud  Also known as intracloud lightning Physics 1010

5.  Ball Lightning  Orbs that float near the ground  Only a few centimeters in diameter  Only last a few seconds Physics 1010

6.  Lightning also occurs in the upper atmosphere, above storms  Also known as sprites  Blue jets are blue energy that bursts out of the thunderstorm  Lightning in the ionosphere  Known as elves  Glowing discs  Can be up to 300 miles in diameter  Only lasts for a thousandth of a second Physics 1010

7.  Most lightning strikes on objects result in fire  up to 50,000 degrees F  Higher voltage than typical household appliances  Invention of the lighting rod by Ben Franklin  Beginning of the alternative path on all houses to prevent power surges Physics 1010

8.  Invented by Nikola Tesla  Used for a wide range of things  Radio transmission  X-ray generation  Helping in current experiments Physics 1010
