Lightning is a huge electrical discharge, or spark, that results from vigorous motions that occur in thunderstorms. While you can be safe in a car in a lightning storm, it is not because of the tires. Rubber tires do act … Continue reading
Space contains tons of dust. When dust particles approach Earth, they can be captured by gravity and enter the atmosphere at very high speeds.
Particles with diameters larger than about 2 millimeters undergo very rapid heating through collisions in our atmosphere. As they heat up, they can produce a short-lived trail of light known as “shooting star.” Most dust particles entering the atmosphere are estimated to be much smaller than this and don’t provide a visible trail.
