The symphony of rotations above representing daily rotation South to North and the slower rotation parallel to the orbital plane as a function of the orbital motion of the planet are responsible for the seasons on that planet.. The same surface rotations relative to either the dark hemisphere of the planet or to the central Sun also reflects the cause the hemispherical seasons on Earth.

An experiment or analogy helps explains the slower surface rotation to the Sun in order to interpret the time lapse above and especially 50 seconds in.

Inform students that the human body represents the Earth with their nose representing the North pole. Ask them to walk around a central object imitating the Earth's running a circuit of the Sun. With their nose pointing constantly in the same direction throughout the circuit, they will enjoy having to walk forwards, sideways, backwards, sideways and completing the circuit facing forwards again. The Earth does this as the North pole faces constantly towards Polaris each circuit.

Explain to the students that at one time or another as their body orbits the centre object (representing the Sun), one side of their body will face the Sun as a function of this orbital motion hence an isolated rotation of the entire surface. Only where daily rotation is absent, at the North/South poles can we get a glimpse of this surface rotation although the expanding and contracting circles with the poles at their centre also help appreciate the symphony.

It is not enough to walk back empirical modelling to pollution concerns and alternative energy supplies as the direction is heading, the introduction of two surface rotations responsible for the seasons is also the gateway into proper climate research.
