Answer:  The rotation of the Earth...

The rotation (spinning) of the Earth causes the sun to appear to move across the sky, as well as to rise and to set. The daily rising and setting of the constellations and the circular motion of the stars around the North Star also result from the Earth's rotation. Planet Quiz Show teams may be asked to distinguish between rotation (spin) and revolution (orbit) as a bonus question.
