How are vibrations made? I have had this arguement with my brother, he says that IF you could walk and make no sound doing it would you still create vibrations that could be transfered and felt through the ground?

Sound and vibrations are basically the same thing. When the vibrations are in the right frequency so that we can hear them, then it is called sound.

Not all vibrations create sound. The wave length of the sound determines what we here. Our range of hearing is small. That is why we don't hear dog whistles. Radio waves are just a different wavelength than sound.

Vibration refers to mechanical oscillations about an equilibrium point.example "spring mass system in equilibrium ie force created by spring & weight of the mass are equal &opposite
but when a small pull is given to it . net down ward force is greater than upward force(spring force) .
step-2 [ mass goes to down till equillibrium .let x be displacement.]
step-3 [at this point release the mass hense the system has net upwad force]
step-4[this restoring force helps to break the stability of system but system wants to be in equilibrium position(x=0) hence vibrate about this position till total stored energy is lost ]"
same case is happening to creat a vibration in each system or molecule at equlibrium ie if we give a small external force to system or molecule at equlibrium & then release it.it is in vibration

Your brother got you on this one.
Just a little thought for you :
A single flap of a butterfly wing changes it surrounding environment forever.
