Question

how are varing lengths of days and night caused​

Answer 1

Answer:

Other planets also experience these changes in day and night length because they too are tilted on their axes. Each planet's axis is tilted at a different angle. Jupiter is tilted only 3 degrees, so its change in day and night length as it moves around the Sun is less extreme than that of Earth.

Answer 2

Answer:

Because The Axis of Earth is tilted by 23.5° toward the Pole Star so at different locations different lengths of days and nights are caused.

The half part of Earth faces sun at a time.
