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.
As far as making noise voluntarily goes, it is quite common for a turtle to do so during battle, courtship, mating and egg-laying. Most turtle noises are hisses; however turtles have also been known to make noises that include grunting, hooting and clucking. What is even more interesting as far as sound goes is that turtles do not have outer ears. They have inner ear structures but do not necessarily respond to noise.
