The rotation of earth about its axis is………..

A vector has both magnitude and direaction . Does it mean that anything that has magnitude and direction is necessarily a vector ? The rotation of a body can be specified by the direction of the axis of rotation , and the angle of rotation about the axis . Does that make any rotation a vector ?

Give the revolution period of our moon around the earth and rotation period of moon about its axis.
