I'm taking a geography class this semester. We learned about lightning. This is what I learned. I made it into a poem :
Lightning
Travels at speed of light (186,000 mi/sec)
Cloud to surface charges move downward in (approx.)
Cloud to surface charges move downward in (approx.)
50-yard sections, producing a path along which a charge is deposited.
The circuit is complete when the charge reaches the surface.
Thunder is a result of lightning.
The air around the lightning bolt is heated to extremely high temperatures
Thunder is a result of lightning.
The air around the lightning bolt is heated to extremely high temperatures
(50,000°F). Pressure from the heat causes the air to expand (explosively), pushing (compressing) surrounding air and causing a shock wave (within first several feet)
then continues as sound waves.
Boom.
Approximate speed of sound: 761 mph (at sea level).

Nothing of this nature should exceed 47 seconds.
The coolest part of the reading was how her dimples shuddered and trembled and grew more pronounced depending on the stretch of her mouth during words.
And the really cute cabbage patch baby.
