Parts of Alaska, June 21st has 24 hour sun.  Winter on Dec. 21st has 24 hr. night.  It's seasonal and depends on the earth's tilt on the axis in relation to the sun.  In the summer, the axis is pointed in such a way that there is no night, in the winter, it's the same with no daylight.

It's not the cold, it's the lack of sunlight. If you can afford it, invest in a full-spectrum lamp.

The graph would show a maximum daylight on June 21 with a minimum of dark, and a maximum of dark on December 21 with a minimum of daylight, but I doubt that it would be sinusoidal, because near the north pole there are extended periods of days with no darkness in the summer, indicating an oscillating function, but not sinusoidal.

The midnight sun is a phenomenon occurring in latitudes north of the Arctic Circle and south of the Antarctic Circle where the sun is continuously visible for at least 24 hours once per year. Since there are no permanent human settlements south of the Antarctic Circle, the countries and territories whose population experiences it are limited to Alaska, northern Canada, Greenland, Iceland, northern Norway, Sweden and Finland, and extremities of Russia such as Novaya Zemlya and the cities of Murmansk, Norilsk and Vorkuta. A quarter of Finland's territory lies above the Arctic Circle, and as a consequence the midnight sun can be experienced — for more and more days, the further north one goes. At Finland's northernmost point, the sun does not set for 73 days during summer.

The above is an incorrect answer. Seasons do not occur because of the distance of the earth to the sun. In fact, during winter, the earth is physically closer to the sun and during the summer, it is furthest.\n\nTilt is key. Its important that not only is there a tilt on the earth, but the direction of that tilt is not altered during the rotation of the earth around the sun.\n\nThe Northern hemisphere is always tilting away during the winter, and towards the sun during the summer. The tilt of the earth is 23 degrees. So lets say you're at 45 degrees lattitude. During the summer, the sun will rise to 45+23 (68) degrees because the tilt is towards it, and in winter, the sun only goes to 45-23 (22) degrees. There is a big difference between the sun going up 22 degrees and the sun going to 68 degrees.\n\nWhen the sun goes to 68 degrees, it is more overhead, and the earth therefore receives more of its rays. During winter, light rays are striking obliquely, and hence do not warm the earth as much.\n\nThis is why there are less variations of seasons around the equator, where the sun is almost always directly overhead all the time.\n\nAnd this is why seasons are reversed on the southern hemisphere. When the northern hemisphere tilts towards the sun, the south is tilting away.

The aurora is a glow observed in the night sky, usually in the polar zone. For this reason some scientists call it a "polar aurora" (or "aurora polaris"). In northern latitudes, it is known as "aurora borealis" which is Latin for "northern dawn" since in Europe especially, it often appears as a reddish glow on the northern horizon as if the sun were rising from an unusual direction. The aurora borealis is also called the "northern lights". The aurora borealis most often occurs from September to October and March to April. Its southern counterpart, "aurora australis", has similar properties

it occurs when solar radiation from the sun interacts with the magnetic field around the Earth (its strongest around the poles..so thats why theres a northern..AND southern lights...and no "Middle" lights lol)\n\ni can't wait to see it some day

Sunny days are the result of high pressure systems which tend to be drier and colder in the winter. There is also no cloud cover at night to keep the reradiation in and if there is snow on the ground it is even brighter and the snow is reflecting the heat back out into space.

The sun actually doesn`t change position, it`s the tilt of the earth that makes it look like it is changing position. When the earth is tilted towards the sun we get more daylight hours (summer), when the earth is tilted away from the sun we get less daylight hours (winter). But we are not warmer cos we are closer to the sun, we are warmer because the angle to the sun is closer to 90 degrees in summer than in winter. If in northern hemisphere then the sun will always be at least a little to the south (even in summer).

the more north during the winter months you go from the equator, the longer the it stays dark, there is one day in a year in North Pole where it will stay dark for 24 hours, the same holds true for the southern hemisphere during its respective winter time.

Because some countries are on the dark side of the Earth, and the sun is not out.

The tilt of the Earth's axis causes the number of daylight hours and the intensity of the sunlight to differ throughout the year. For example, our "shortest" day (least amount of sunlight) of the year will be on Dec. 20 or 21st (one of them, I forget). That is the time that the Earth is positioned in it's orbit around the sun such that the tilt of the Earth's axis makes the northern hemisphere tilt away from the sun for the maximum amount of time. This sparks the Winter season . We are getting less and less sunlight up to that point and gradually increase sunlight after that until six months later (June 20 or 21, I forget), we have our "longest" day. This sparks the 'Summer' season.\n\nSo, why isn't Dec. 21 our coldest day? Well, the Earth's surface retains heat from the warmer months. Even though we increase sunlight after Dec. 21, it is not enough to warm the surface until some months later. Likewise, June 21 is not our hottest day because after June 21, we still get enough sunlight to bake the surface and continue to heat the ground. It is not until about the time that the sun crosses the equator that we have Fall and Spring.\n\nIf you shine a flashlight at a tennis ball, you'll notice that about half of the ball gets direct light, but that the center of the ball gets the most. Think of the Earth as the ball and the sun's focal center is constantly moving up or down throughout the year.

Solar heating is more pronounced at the equator where rays are vertical and closely spaced. At higher latitudes there is less heating, rays less dense, more oblique. The tilt of the earth's axis introduces a further, seasonal variability. Seasons occur in opposite months of the year in opposite hemispheres. Winter in the northern hemisphere is simultaneous with Summer in the southern hemisphere.\n\n--assume you are looking at earth broadside, equatorial view, for the following, throughout (no polar views)--\n\nEQUATORIAL HEATING\nAir masses at the equator have an eastward inertia. As they are heated, these masses expand and rise. Keep the inertia in mind as you read all of the following.\n\nConsidering first the northern hemisphere, as this high equatorial rising air pushes to the north it has a higher speed eastward relative to the earth's surface. This is because the eastward inertia of a mass of air varies at different latitudes. \n\nAir at the equator is moving faster, along with the rotating earth, than is air at higher latitudes. Identical for both hemispheres, north and south: Air at higher latitudes has less eastward speed.\n\nOn the equatorial surface cooler air moves in from the northeast and the southeast. This air is moving west because it has less eastwards inertia as it approaches the equator, from higher latitude. These are the Trade Winds, blowing east to west on both sides of the equator.\n\n\nNORTHERN HEMISPHERE\nAs the hot, rising air from the equator cools at higher latitudes and sinks in the latitude 30's region, some moves further north and eastwards, some moves further south and westwards.\n\nSOUTHERN HEMISPHERE\nAs the hot, rising air from the equator cools at higher latitudes and sinks in the latitude 30's region, some moves further south and eastwards, some moves further north and westwards.\n\nThe northern and southern hemispheres are mirror opposites.\nWe see that these movements are caused by the heating effect of the sun. \n\nWe see that in the northern hemisphere cold air moving south veers to the left (westward) and warm air moving north veers to the right (eastward). The accounts for the clockwise highs and counterclockwise lows.\n\nIn the southern hemisphere, cold air moving north veers to the west and warm air moving south veers to the east. The net effect here is counterclockwise highs and clockwise lows.\n\nIf one has a hard time picturing this, just remember, highs and lows spin in opposite directions. Lows are clockwise in the southern hemisphere and counterclockwise in the northern hemisphere.\n\nWinds blow from high to low pressure. The denser the isobars (lines of equal pressure) on the weather map, the greater the wind speed. Highs are the directors, lows are the actors.* This means the hurricane will have a fit wherever it is guided by high pressure.\n\n*Rodewald, German meteorologist\n\nThis explanation says little about weather from 30 degee latitudes further north or south. To describe the entire globe in detail is impractical here. The principal forces involved in your question have been described.\n\nFor a more detailed explanation, I recommend OUR ATMOSPHERE, by Theo Loebsack, A Mentor Book\n\nYes, every time I think about all this, my head spins. Try to think very carefully and hard about it occasionally and it will become somewhat clearer.\n\nThe important thing to remember is what is happening on the ground where most of us live and work. Since LOWs are the big actors, remember they are counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.\n\nA very good exercise, especially for sea goers, is to picture the wind directions you would experience from various compass points surrounding a ferocious low. Do this remembering which hemisphere you are in, north or south. Understanding that could mean survival. You want to avoid everything, to the extent possible, but especially the eye wall. The innermost winds are the most horrific, w

Answer is C.\n\nThe seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees of arc. Thus, at any given time during the summer or winter, one part of the planet is more directly exposed to the rays of the Sun (see Fig. 1). This exposure alternates as the Earth revolves in its orbit. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons (see Fig. 2 and Month ranges of seasons (below) and Effect of sun angle on climate).\n\nSeasonal weather fluctuations also depend on factors such as proximity to oceans or other large bodies of water, currents in those oceans, El Niño/ENSO and other oceanic cycles, and prevailing winds.\n\nIn the temperate and polar regions, seasons are marked by changes in the amount of sunlight, which in turn often cause cycles of dormancy in plants and hibernation in animals. These effects vary with latitude, and with proximity to bodies of water. For example, the South Pole is in the middle of the continent of Antarctica, and therefore a considerable distance from the moderating influence of the southern oceans. The North Pole is in the Arctic Ocean, and thus its temperature extremes are buffered by the presence of all that water. The result is that the South Pole is consistently colder during the southern winter than the North Pole during the northern winter.\nThe cycle of seasons in the polar and temperate zones of one hemisphere is opposite to that in the other. When it is summer in the Northern hemisphere, it is winter in the Southern hemisphere, and vice versa, and when it is spring in the Northern hemisphere it is autumn in the Southern hemisphere, and vice versa.\n\nIn the tropics, there is no noticeable change in the amount of sunlight. However, many regions (famously the northern Indian Ocean) are subject to monsoon rain and wind cycles. Curiously, a study of temperature records over the past 300 years (David Thompson, Science, April 1995) shows that the climatic seasons, and thus the seasonal year, are governed by the anomalistic year rather than the tropical year.\n\nIn meteorological terms, the winter solstice and summer solstice (or the date maximum/minimum insolation) do not fall in the middle of winter and summer respectively. The heights of these seasons occur up to a month later due to seasonal lag. Seasons though, are not always defined in meteorological terms; see reckoning\n\nCompared to axial tilt, other factors contribute little to seasonal temperature changes. It's a common misconception that the seasons are the result of the variation in Earth’s distance to the sun due to its elliptical orbit.[1] Orbital eccentricity can influence temperatures, but on Earth, this effect is small and is more than counteracted by other factors; research shows that the Earth as a whole is actually a few degrees warmer when farther from the sun.[2] Mars however experiences wide temperature variations and violent dust storms every year at perihelion.[3]\n\nYou could get more information from the link below...

The sun appears at night in places in the far northern reaches during June. North of the Arctic Circle (66.5 degrees north latitude), the "midnight sun" appears.\n\nThe phenomenon also occurs around the winter solstice in the southern hemisphere, but south of the Antarctic Circle (66.5 degrees south). So it's not in any single country, but those places north or south of the given lines of latitude.

Actually there are two effects going on here, both of which result in New Hampshire having an earlier sunset.  One effect is exactly what your husband said.  The people on the western edge of a time zone will have later sunrises and sunsets than those on the eastern edge.  The other factor is that NH is farther North than GA, which means it will have shorter days in the winter.
