What dates does the circle of illumination pass through the North Pole and south pole Both?
The circle of illumination, which separates day from night, passes through the North Pole and South Pole during the equinoxes, occurring around March 21 (vernal equinox) and September 23 (autumnal equinox). On these dates, the Sun is positioned directly above the equator, resulting in nearly equal day and night lengths worldwide, including at the poles.
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 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 time of year does the cirle of illumination pass through the North and South Poles?
The circle of illumination passes through both the north and south poles only twice each year, on the spring and autumn equinox. The spring equinox occurs around March 20 and the autumn equinox occurs around September 22.
What is a segment that passes through the center of a circle and has both endpoints on the circle?
A diameter is a segment that passes through the center of a circle and has both endpoints on the circle.
What is called a line passing through the center of a circle with both endpoints on the circle?
This is the diameter of the circle.
Line passing through the center of a circle with both end points on the circle?
That's a diameter of the circle.
Does the Arctic Circle pass through Norway Sweden and Denmark?
The Arctic Circle passes through both Norway and Sweden but it does not pass through Denmark.
Has both end points on circle and runs through it?
The Diameter
What is a line passing through the center of a circle with both end points on the circle called?
This is a line segment called a diameter of the circle.
What is a straight segment with both endpoints on the circumference of a circle?
This is referred to as a chord. If the chord passes through the center of the circle, it represents the diameteror width of the circle.
Does the Arctic Circle pass through the US Canada or Mexico?
Both Canada and the US (through Alaska).
