The word day may also refer to a day of the week or to a calendar date, as in answer to the question, "On which day?" The life patterns of humans and many other species are related to Earth's solar day and the day-night cycle (see circadian rhythms).

Jun 5, 2017 ... The change between day and night is caused by the rotation of the Earth on its axis. If the Earth did not rotate as it does, the day/night cycle would be very different or possibly even nonexistent. The changing lengths of days and nights depends on where you are on Earth and the time of year. Also, daylight ...

There are differences, however, in the length of day and night — the cycles are made even more complex by the tilt of a planet's axis and its rate of orbit. Some planets rotate faster than Earth and some rotate slower. Mars has a day and night cycle similar to Earth. Mars rotates on its axis once every 24.6 hours. Venus turns  ...

Dec 11, 2014 ... For most of here on planet Earth, sunrise, sunset, and the cycle of day and night ( aka. the diurnal cycle) are just simple facts of life. As a result of seasonal changes that happen with every passing year, the length of day and night can vary – and be either longer or shorter – by just a few hours. But in some ...

One side of the Earth faces the sun, while the other side faces away into space. The side facing the sun is bathed in light and heat—we call this daytime. The side facing away is cooler and darker, and experiences night. Because the Earth is constantly spinning, the line between day and night is always moving around the  ...

Jun 14, 2010 ... The summer solstice that falls this year on June 21 marks the longest day of the year in the Northern Hemisphere, sunlight-wise. Almost imperceptibly, however, Earth's daynight cycle—one rotation on its axis—is growing longer year by year, and has been for most of the planet's history. Forces from afar ...

The cycle of night and day is continuous, except near the North and South Pole. If the Earth's axis was perpendicular to its orbital plane, all places on Earth would experience equal amounts of day and night: 12 hours of day and 12 hours of night. However, the Earth's axis is actually tilted at an angle of 23.4°. This means that ...
