What affects day and night

The rotation of the earth

Explanation:

An average of 12 hours of light per day is received by each location on Earth, but the exact amount of hours of daylight on every given day of the year varies from place to place. Locations near the equator of the Earth produce only about 12 hours of light a day. In comparison, for a few months in the summer, the north pole experiences 24 hours of sunshine, and complete darkness for months in the winter. A long sunrise and a long sunset distinguish these two approximate periods of light and dusk.

The Planet orbits the sun once every 365 days and rotates once every 24 hours along its axis. The Earth's rotation on its axis is due to day and night, not its orbiting around the sun. The word 'one day' is determined by the time it takes for the Planet to spin once on its axis which requires time for both day and night.
