The correct answer is The rotation of the Earth
Explanation:
Besides orbiting around the Sun which leads to seasons, Earth is all the time rotation on its axis, this movement occurs eastward and the movement is completed every 24 hours, due to this, a day is considered to last 24 hours. Besides this, due to the rotation of Earth different zones or areas in the planet are directly exposed to the sunlight during different periods, which leads to daytime and nighttime, considering daytime as the period in which a zone is illuminated by the Sun while in the nighttime the zone remains in the dark. Additionally, this phenomenon also explains why daytime and nighttime do not occur at the same time on all Earth. Thus, it is the rotation of the Earth the one that causes Earth to experience daytime and nighttime.
