Expert Answer:

Motion of earth around the sun is a two dimensional motion, because only two coordinates changes while earth moves....ie it is moving in elliptical orbit in a plane say X-Y plane changing x and  y  coordinates.
 
the motion of an aeroplane in the sky a three dimensional one because it chnges its x, y coordinates along with z coordinate wrt a reference point.
