A clade (or monophyletic group) is a group of species that includes an ancestral species and all of its descendants (i.e. members within the clade are all more closely related to each other than any members outside the clade).
What makes lightning make noise? Thunder is the sound that lightning makes. Sounds simple but why does lightning make a sound. Any sound you hear is made up of vibrations, the vibrations travel through the aiâ¦r as waves until they reach your ear.This means lightning must cause some vibrations.Lightning is a huge discharge of electricity.
While heat lightning is really just ordinary lightning from a far away thunderstorm, the typical sound of rumbling thunder is muffled either by long distances or by a blocking, mountainous terrain. The cracking sound of lightning is thunder, which results from the rapid expansion of hot and cold air masses. Another reason no sound accompanies heat lightning is the idea that thunder travels much more slowly than light, and it's unlikely to hear thunder from a distance greater than 10 miles. The distribution of hot and cold temperatures around a thunderstorm causes sound waves to be bent, or refracted, upward into the sky rather than toward the ground where an observer may be listening.
