Sarah, who lives in Australia notices that the length of the shadow of the flagpole is getting shorter every day when measured at noon. Paul, who lives in Canada, notices that the length of the shadow of the flagpole is getting longer everyday when measured at noon. Draw a model to explain how both students can be observing this at the same time. Include these in your model: Sun; earth; tilted axis; rotation and revolution.

Time zone is one important factor in difference in location and this in turn affects the result of the resolution and rotation of shadow produced from the sun or other illumination.

Therefore someone at a place might see a clear large shadow due to shinny sun reflection and another a small or dull Shadow at same time if the intensity of the sun or lighting source is going down.

Explanation:

The closer a body/object is to a lighting source the larger the shadow it produces, and the farther the body the smaller the shadow produced.
