Main Question or Discussion Point

i've been learned gyroscope, but i have a litte thing which makes me confuse.

Does earth feel the gyroscopic effect?
if the means of gyroscope is "if there is things which rotated on the different axis(x- axis,y- axix) so you will get moment on the other axis (z- axis)".
Is that causes earth rotates tilt?

No. Once a planet rotates, centrifugal forces stretch it slightly, increasing its moment of inertia about axis of rotation, making it it a principal axis. There could be light precession due to mountains, etc, but it's going to be a very tiny change in axis angle.

Gyroscopic effect helps maintain orientation of the rotational axis, however. If it wasn't for gyroscopic effect, it'd likely drift slowly over time, and that would not be good for life on this planet.
