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.
Thunder can be heard up to 25 miles away from the lightning discharge. At these distances, thunder sounds like a low rumble because the higher frequency pitches are more easily absorbed by the surrounding environment, and the sound waves set off by the lightning discharge have different arrival times.
