Where do tornadoes form you the sky or on ground?

Do all tornadoes touch the ground?
By definition a tornado must be in contact with both the ground and the cloud base. So, in that sense, yeas. But this only means that the violent circulation must make this connection, not necessarily the visible funnel. Additionally, sometimes a tornado starts to form, but dissipates before touching down, but in that case it is not considered a tornado.

Do tornadoes start at the bottom?
No, Tornadoes start inside the clouds of their parent thunderstorms and descend towards the ground. Somtimes they can appear to form up from the ground because the vortex is just swirling air when it reaches thr ground and therefore cannot be seen until it starts picking up dust from the ground.
