Chop and turbulence are not the same.

The definitions above are for the 3 main categories of turbulence. There are only 2 categories of chop that I am aware of, light and moderate.

Light chop is like driving over cobblestones - a continuous 'bumping' or rumbling type of sensation. It tends to have a fairly regular and rapid rythm. Moderate chop, a more exaggerated version of light chop, with more obvious 'bumps'. Neither one leads to any noticeable change in aircraft attitude, altitude or speed. Anything more bumpy or unpleasant falls into the category of turbulence.
