The spinning of our word on its axis of rotation (which passes through the geographical north and south poles).
12hours in a day and 12 hours in a night
The rotation of the earth causes night and day.
Although equinox means equal night, it doesn't mean that the day and night exactly the same. They are close. After the autumnal equinox the days are shorter though.
Day and night are caused by the rotation of the Earth on its axis. As the Earth rotates, different parts of the planet are either facing towards the Sun (day) or away from the Sun (night). This rotation takes approximately 24 hours to complete, creating the cycle of day and night.
well it schould be how long do jiraffes sleep and your answear is 12hours half a day and they are not noctornal animals they sleep at night usually in groups /herds!
The Earth rotating causes day and night, it rotates every 24 hours. The Earth rotating causes day and night, it rotates every 24 hours.
The spin of Earth causes day and night. The sun is visible from one hemisphere but not the other.
rotation
Rotation of the planet on its axis causes night and day to happen on all planets. This rotation causes different parts of the planet to face the sun at different times, leading to periods of light (day) and darkness (night).
rotation
No "event" causes that.The continuous rotation of the planet on its polar axis it responsible for the progression of day and night.
It is not like that. Earth revolves around the sun and Earth is sphere and when suns rays fall on earth the half earth gets light but half did not get it. Since Earth rotates about its own axis slowly the half sides gets alternately as 12hours and 24 hours as a day. In one day 12hours get half Earth light and next 12 half night that is no light
