What is the relation between the North and South Poles and the circle of illumination on March 21 and September 22?
March 21 and September 22 are dates of equinox. On this date, not only do the seasons change, but at the poles, the sun either rises or sets for the year, depending on the pole.
As well, on these dates, the polar circles -- about 66.5 degrees N and S -- experience the single 24-hour period with no sunset or no sunrise, again depending on the polar region.
Between the circles and the poles, the period of annual no sunrise/ no sunset varies from the single 23-hour period at the circles to six months at the poles.
What else can I help you with?
If the countries lie between the Tropic of Cancer and Antarctic circle and between the Tropic of Capricorn and Antarctic circle how many seasons occur?
Everywhere on earth, four seasons occur: summer, fall, winter and spring. In the northern hemisphere, summer begins on June 21. In the southern hemisphere, summer begins on December 21. These are the solstice marks. Equinox marks -- March 21 and September 21 -- signal the beginning of the relative seasons.
What does the radius of each circle represent in science?
In science, the radius of a circle typically represents the distance from the center of the circle to any point on its circumference. This can be used to calculate various properties such as area, circumference, and relationships between different geometric shapes.
What is the latitude between in frigid zone?
The frigid zones are located between 66.5 and 90 degrees latitude, both north and south of the equator. These regions are characterized by cold temperatures and extreme winter conditions due to the tilt of the Earth's axis away from the sun.
USA state with the longest summer day?
Alaska, specifically locations north of the Arctic Circle, experience the longest summer days in the USA due to the midnight sun phenomenon. In cities like Barrow or Utqiaġvik, the sun does not set for several weeks during the summer solstice, resulting in extended daylight hours.
Who crawls out of the forest into the circle?
A man crawls out of the forest and into the circle.
What is circle of illumination?
the circle that divides the day from night is called circle of illumination
What is a circle of illumination?
the circle that divides the day from night is called circle of illumination
What is the relation between arc and circle?
An arc is a part of the circumference of a circle.
What is the relation between circle and pi?
The circumference of a circle divided by its diameter is equal to the value of pi.
Why is pi used in every circle formula?
By definition Pi is the relation between the radius and circumference of a circle.
On what dates is the circle of illumination exactly tangent to the Arctic Circle?
The circle of illumination intersects the North Pole on the spring and autumnal equinoxes, March 20 or 21 and September 22 or 23, when the Earth's North and South Poles are not tilted toward or away from the sun, but are both at 90 degrees to the sun's rays. The sun is directly above the equator, and every location on Earth has 12 hours of daylight.
What is the relationship between the area and the radius?
In relation to the area of a circle: pi*radius^2
The circle of illumination just touches the Antarctic Circle on what date?
The Antarctic Circle never receives direct sunlight. The closest it ever gets is on December 21, when the sun ascends to 43 degrees away from being overhead at noon on the Antarctic Circle. But that's the highest the sun can ever get there.
What is the relation between area of a sector and length of an arc of a circle?
There is no direct relation between the area of a sector and the length of an arc. You must know the radius (or diameter) or the angle of the sector at the centre.
Does the solar system's circle of illumination divide day from night?
yes
Why circle of illumination does not divide all the latitudes from its center?
Well, once I looked up "circle of illumination" --(geology) The edge of the sunlit hemisphere, which forms a circular boundary separating the earth into a light half and a dark half. (circle-of-illumination) --I could just *begin* to understand your question, which is still very unclear. Please rephrase it. It just doesn't make sense.
What is a tangent ray?
The north or south most point of the insolations circle of illumination.
