In general, the sun rises in the east and sets in the west because of the Earth's eastward spin. However, depending on where the observer is in relation to the equator and the time of year, the sun rises and sets either to the north or to the south of due east and due west. In fact, it is only on two days, the spring and fall equinoxes, that the sun rises due east and sets due west.Continue Reading
The Earth spins around its axis once every 24 hours, and it is this motion that makes the sun, the moon and the stars appear to rise and set every day. However, because the Earth is inclined at an angle (23.5 degrees), its poles tilt towards or away from the sun depending on the time of year. For an observer in the Northern hemisphere, this means that in summer, the sun rises in the northeast and sets in the northwest, while in winter, it rises in the southeast and sets in the southwest.
On the day of the summer or winter solstice, the sun rises and sets at its most northern or southern location. How far north or south the sun appears on the horizon on any give day depends on latitude. For example, as one travels farther north in winter, the sun rises and sets farther to the south. In fact, beyond the Arctic Circle, there are days in December when the sun never rises above the horizon, conversely there are days in June when it never sets.Learn more about Hours, Minutes, & Seconds
The time 12:00 noon, no matter the area on the Earth, is neither a.m. nor p.m. The same is true of 12:00 midnight, as it is neither a.m. nor p.m. as well. However, it is widely accepted that noon is considered p.m. and midnight is considered a.m. informally.Full Answer >
The sun actually does not rise or set; it is only perceived as rising or setting because of a person's vantage point on the surface of the Earth. This perception of the sun rising and setting is due to the rotation of the Earth itself.Full Answer >
The Earth spins on its axis due to angular momentum conservation. The Earth was formed when leftover gas from the sun condensed into planets. As the gas cooled, it condensed, which caused the Earth to start spinning. Because it is no longer condensing, the Earth will keep spinning at a steady rate and will continue to do so unless it is stopped by some external force.Full Answer >
The Earth rotates at about 1037 miles per hour at the equator, and the speed at the North Pole and South Pole is near zero. The speed of the Earth's rotation increases when approaching the equator and decreases toward the poles.Full Answer >
