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.
The lightning and thunder sound occur at the same time, but an observer will experience a delay in hearing the thunder depending on the distance from the lightning strike.  â¦  Light travels at slightly less than 3.00 x 106 kilometres/second or around 1.88 x 106 miles/second. That is fast.
