Expert Answer:

lightning can be seen by the human eye as a beam of white light that comes and goes in a blink of the eye. It might seem exciting to some people but scary to many. It is actually an atmospheric release of electricity with sound known as thunder, which is caused by a natural atmospheric process, mainly during thunderstorms in the rainy season. A lightning bolt can travel at the unbelievable speed of 60,000 mph and can reach temperatures of up to 30,000 degrees 
 
  • Forked lightning is lightning in which visible branches are present.
  • Streak lightning is a bolt that appears to be a single arc shaped line.
  • Ribbon lightning is viewed as parallel streaks of light. It is caused when winds separate the strokes of the bolt.
  • Chain lightning (also called Bead lightning) is characterized by a bolt that breaks into dotted lines as it fades.
  • Ball lightning's appearance is that of a fiery glowing ball (usually in red, yellow, or orange) which floats several feet above the ground. It can be as big as a grapefruit in size. It has also been reported to have been floating within houses and barns. It is unknown why ball lightning occurs and what it is made of.
