9. Which zone has 24 hours of daylight on (a) June 21 (b) December 22?

Answer 1

(a) June 21 = The Arctic
(b) December 22= The Antarctic

On June 21st. the equator receives twelve hours of daylight, there's 24 hours of daylight at the North Pole and areas north of 66°30' N, and there's 24 hours of darkness at the South Pole and areas south of 66°30' S. The reverse is true on Dec. 22.

In the northern hemisphere, the Winter solstice is day of the year (near December 22) when the Sun is farthest south. However, in the southern hemisphere, winter and summer solstices are exchanged so that the winter solstice is the day on which the Sun is farthest north. The winter solstice marks the first day of the season of winter. The declination of the Sun on the (northern) winter solstice is known as the tropic of capricorn (-23° 27').

Answer 2

Antartica has daylight 24-7 on June 21. Don;t know other one though. And it's the 21 on both- not 22.

Answer 3

Northwest Territories: CANADA

The "shortest" day of the year within the northern hemisphere is December 21st, the Winter Solstice. This is when the northern latitudes of the planet are tilted furthest away from the light and heat of the sun.

The corresponding "longest" day is June 21st, the Summer Solstice. "Shortest" and "longest" refer of course to the duration of sunlight.
