That's right, motion cannot be measured unless you have some frame of reference within which to measure it.
It is called "reference frame"; and yes, that's the basic idea - related to what will you measure movement.
A tree can be used for a frame of reference for the motion of a snowboarder.
True. A frame of reference must be specified - or implied. (Movements are often assumed to be in relation to the ground, i.e., to our planet Earth.)
since by definition motion is 'The act, process, or state of changing place or position; movement; the passing of a body from one place or position to another, whether voluntary or involuntary; -- opposed to rest', then frame of reference (according to the physics def.) is the coordinates used to measure this motion. also, many people modify frame of reference by using sub categories, such as observational reference frame, which implies that we care about the state of motion more. macroscopic and microscopic frames of reference set themselves apart by focusing on the scale of observations.

Frame Of Reference. which means a framework that is used for the observation and mathematical description

the inertial reference frame is not absolute. because motion is not absolute. motion is relative depends on who's looking/observing.
Motion is relative to an observer's frame of Reference.
Relative motion is movement in relation to a frame of reference.

usually the motion of your frame of reference is 0. When you are in a train going 50 mph, your frame of reference would be you are going 0 mph and the tracks are traveling at -50 mph.
