The Earth's yearly orbit round the Sun and the tilt of the Earth's rotational axis as compared to the plane of the orbit.

The further you go away from the equator towards the poles, the greater the seasonal temperature and daylight variations.

Nothing can change the length of day and night except the normal seasonal progression.
Variations of day length greatest? North and South Pole Variations of day length least? Equator Variations of temperature least? Equator
Thermal expansion means that the length of the bridge changes.
The primary cause of annual temperature variation is axial tilt. Axial tilt results in seasonal day length variation. The longer the night, the more daytime heat is radiated back into space. A much smaller, secondary cause would be orbital eccentricity.

The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
