[′tak·ə‚klīn]
(astronomy)
A zone of radial shear in the interior of the sun that is located at the base of the convection zone at a distance from the sun's center equal to about 0.7 of the sun's radius, and represents an abrupt transition from the rotation rates in the convection zone to those in the underlying layers.

Consequently, the shear nature of the tachocline, and the fact that it displays a prolate nature, provides clear evidence that the solar body is physically structured.
The Sun with its oscillations, mass displacements, shape, internal layers (convection zone, tachocline, and core), and atmospheric waves, has highlighted that it belongs in the company of solids and liquids.
