Why does Antarctica get 24 hours daylight in December and 24 hours darkness in June?
Antarctica has its longest days in December, which is summer in the southern hemispher, and its longest nights in June, which is winter. At the Pole, the sun never rises during the shortest days and never sets during the longest days.
What is the relationship between the temperature and the number of daylight hours?
In general there is a delay between the highest daylight hours and highest temperatures and between lowest daylight hours and lowest temperatures. The reason is energy absorbed. When the sun is pounding down during the summer the highest temperatures come approx 1 month after the longest day of the year because the enrgy absobed on the earth in the oceans and on land has a commulative effect. The same thing happens in winter.
Why are the days in summer long and nights short while in winter days are short and nights are long?
Assuming you're in the United States, the longest day of the year is the first day of summer. The shortest day of the year is the first day of winter. Daylight hours get progressively shorter after the first day of summer until they reach their shortest, again this being the first day of winter. Therefore, the last day of autumn is the day before the day with the shortest number of daylight hours. So to answer your question, autumn does contain some days in December with the shortest number of daylight hours in the entire year. Hope that helps.
When do the polar regions receive darkness for 24 hours?
Only regions north of the Arctic Circle, or south of the Antarctic circle, will experience at least one day without sunlight during the year. The closer one gets to the pole, the more days will occur without sunrise, and conversely the same number without a sunset. At either of the poles, there is 6 months of daylight and 6 months of night. The equinoxes are the starting and ending of the polar day/night, so the farther away from the poles, the later in the season the day of no sunlight will occur, and the earlier the day of no night.
Why is day and night the same on the vernal equinox?
This happens at both the vernal and autumnal equinoxes.The equinoxes are the points in the earth's orbit of the sun when the Sun is positioned directly over the Earth's equator. This only happens twice a year because the earths axis of rotation is inclined approximately 23.44° from the plane of the orbit round the sun. Thus when the north pole is pointing at the sun the south pole is permanently in darkness and at the other end of the orbit when the south pole is pointing at the sun the north pole is permanently in darkness - this gives us summer and winter.Now when the earth is 1/2 way between summer and winter positions (a day in spring and autumn) the axis of rotation is not pointing at the sun at all which means that both the north and south poles are illuminated evenly and each get 12 hours of daylight and 12 hours of night. This happens all over the planet and is the day of the equinox equinox.
Why are the number of daylight hours and darkness not the same on earth?
It depends on your location, in some places they are
WHAT 2 DAYS OF THE YEAR DO NORTHERN AND SOUTHERN HEMISPHER HAVE THE SAME HOURS OF DAYLIGHT AND DARKNESS?
21 April and 21 September.
Is the number of hours of daylight the same all over the world?
yes
In the spring and fall, the hours of daylight and darkness are the same on what two days?
March equinox and September equinox : Daylight and darkness are of equal length on both the Vernal Point (Spring/March 20th 2011) and the Autumnal Point (Autumn/September 23rd 2011) .
How long is sunlight in a hot desert?
The length of day in any desert depends upon its latitude and the season of the year. It has nothing at all to do with the fact that it is a desert. A desert would receive the same amount of daylight as a non desert region at the same latitude.
How many hours of darkness are there in one day?
It depends on where you are and what season it is. If you are at the equator then there is 12 hours of daylight and 12 hours of night. If you are above the arctic circle then during the winter there is 24 hours of darkness each day, this will occur on Dec. 21st. If you are further above the arctic circle the darkness can last for months. During the summer there will be 24 hours of daylight on June 21st, and again this can last for months if you are very far north. The same is true for the South pole as well.
What date has the longest number of daylight hours. Why is this not the same as the middle of the summer season?

Which month does Houston have the longest number of daylight hours?
June, same as the rest of the northern hemisphere
About how many hours of daylight will there be in the Northern Hemisphere on the fall equinox?
The equinox is the point in time where the Sun crosses the equator and there is no tilt to the Earth, thus there are approximately the same number of hours of light and darkness in both hemispheres. The term "equinox" comes from the Latin aequus (equal) and nox (night).
Are there always the same number of daylight hours as dark in a year no matter what latitude?
sometimes your mum can be a slag
Is the autumnal equinox the longest day?
An equinox is not the shortest day. It has the same amount of daylight and darkness. The solstices have the longest and shortest days. The winter solstice is the shortest day of the year in terms of the amount of daylight.
Are the nights long in a desert?
The lengths of days and nights in the desert are the same as with any area of the world at the same latitude. In the summer the nights are short while in the winter the nights are long. Over a year's period they average 12 hours of daylight and 12 hours of darkness per day.
