How are solstices and equinoxes different from each other?
Solstices and equinoxes are different in terms of the position of the Earth in relation to the sun. Solstices occur when the Earth's axis is tilted either towards or away from the sun, resulting in the longest or shortest day of the year. Equinoxes, on the other hand, occur when the Earth's axis is not tilted towards or away from the sun, resulting in equal day and night lengths.
What phenomenon results when the moon's period of rotation and revolution are the same?
When the moon's period of rotation is equal to its period of revolution, it results in synchronous rotation. This means the same side of the moon always faces the Earth.
How long does a complete precession cycle take?
A complete precession cycle, such as Earth's axial precession, takes around 26,000 years to complete. This gradual shift in the orientation of Earth's axis affects the position of the equinoxes and solstices over this timescale.
Did people go by the stars for growing crops and harvesting them?
Yes, ancient civilizations often used the stars to track the changing seasons for planting and harvesting crops. They relied on celestial events like solstices and equinoxes to know when to plant and when to harvest. This practice helped them align their agricultural activities with the natural rhythm of the Earth.
What seasons do equinoxes occur?
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.
How long does a season last?
91 and a fraction days. The dividing points are the two solstices and two equinoxes. You can see the precise dates of the equinoxes and solstices on the "Earth's Seasons" web site at the US Naval Observatory, at the link below.
How are season and solstice are related?
Solstices and Equinoxes are points in the orbit of the Earth around the sun, hence directly related to seasons
How does the position of earth determine whether it is one of the solstice or equinox days?
The solstices occur at the points where the Earth is either closest to, or farthest away from, the Sun. The equinoxes are the mid-points between the solstices - where the day & night are of equal length.
How are the words season and solstice related?
Solstices and Equinoxes are points in the orbit of the Earth around the sun, hence directly related to seasons
Why would space aliens care so much about Earth solstices and equinoxes?
Because they would want to study our resorces, the way we live.
What courses the seasons on earth?
the revolution of earth and the solstices that occur every once a...... don't know!!
Are there different end dates for spring depending on the year?
Yes, the date of each of the equinoxes and each of the solstices varies from year to year due to the differences between a calendar year (365 or 366 days) and an average actual year (about 365.24219878 days). The dates of the solstices and equinoxes also vary depending on where you are on earth, since there are always at least two days in progress on earth at any given time.
Why the dates of the solstices and equinoxes vary?
The dates of the solstices and equinoxes vary because Earth's orbit around the sun is not a perfect circle, but an ellipse, causing the speed at which Earth moves around the sun to vary. Additionally, gravitational pull from other celestial bodies, such as the moon and planets, can also influence Earth's orbit and the exact timing of these astronomical events.
How are the words season equinox and solstice related?
Solstices and Equinoxes are points in the orbit of the Earth around the sun, hence directly related to seasons
What are some dates of the event of an solstice and an equinox?
The solstices are generally on June 21 and December 21; the equinoxes are usually on March 21 and September 21. These dates can vary a day or two either way, depending on the cycle of leap years. The U.S. Naval Observatory publishes a web page called "Earth's Seasons" which lists the dates and times of the solstices and equinoxes for each year, down to the minute. See the link below.
If earth's axis were tilted 45 degrees at what latitudes would the sun be directly overhead on the solstices and the equinoxes?
If Earth's axis were tilted 45 degrees, the sun would be directly overhead at latitudes of 45 degrees north on the summer solstice, 45 degrees south on the winter solstice, and would pass through the equator on both equinoxes.
What latitude for Arnold is the sun directly overhead at noon on the equinox and solstice?
There is no latitude on earth at which the sun would be directly overhead at noon on the equinox and the solstice.
