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.
Where does the length of day remain the same throughout the year?
At the equator, the length of day remains relatively constant throughout the year, with approximately 12 hours of daylight and 12 hours of darkness. This is due to the tilt of the Earth's axis in relation to the sun, resulting in consistent day length.
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.
Can the whole Earth be lighted at the same time?
No, the whole Earth cannot be lit at the same time due to the natural rotation of the planet. This rotation causes different parts of the Earth to be in darkness while others are in daylight.
Does an equinox occur on the same day at the same time in both hemispheres?
Yes, an equinox occurs when the plane of Earth's equator passes through the center of the Sun, resulting in nearly equal periods of daylight and darkness. This event happens at the same time globally, so the equinox occurs on the same day and time in both hemispheres.
Why are the number of daylight hours and darkness not the same on earth?
It depends on your location, in some places they are
Are the hours of daylight and darkness in September equal to March hours of daylight and darkness?
They're the same length on either side of the date of the equinox, which falls in March and September. In 2009 those dates were 3/20 and 9/22, respectively. Just count days on either side of those dates, to answer our question. What ends up happening, is that the first 20 days of March will have roughly the same length of daylight as the 20 days AFTER the September equinox (i.e. 9/22 thru 10/11). Similarly, the first twenty days of September will have the quality of daylight shown for the first 20 days after the spring equinox (3/20 thru 4/9)
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
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.
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.
Which month does Houston have the longest number of daylight hours?
June, same as the rest of the northern hemisphere
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
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).
Daylight and darkness conditions in various latitudes at the solstices and equinoxes?
At the equinoxes, day and night are roughly equal in length at all latitudes. During the summer solstice in the Northern Hemisphere, there are long daylight hours and short darkness hours, while in the Southern Hemisphere it experiences the opposite. The winter solstice is reversed, with longer darkness hours in the Northern Hemisphere and longer daylight hours in the Southern Hemisphere.
