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.
It was not until the turn of the 20th century that consensus was reached in the scientific community about the origin of thunder. Thunder is the sound generated by lightning produced by a sudden and violent expansion of super-heated air in and along the electrical discharge channel path. Thunder can be a sharp or rumbling sound. The intensity and type of sound depends upon atmospheric conditions and distance between lightning and the listener.
