Why in USA sun appears lower on horizon in evening time than in places nearer to equator like India?
599168
In the mid-latitude regions like the 48 contiguous states of the US, the path of the sun (the ecliptic) across the sky is lower than it is in the tropics. \n\nIf you lived at the equator, the sun would pass directly overhead at true noon on an equinox day (it passes directly overhead where I live this week, and again in July). We say this is 90 degrees from the horizon.\n\nIf you lived at one of the poles, the sun would barely skim the horizon in the summer--getting only as high as 23.3 degrees, and not appear at all in winter. \n\nIf you lived at 45 degrees latitude north, the highest the sun would ever get in your sky is about 68 degrees from the southern horizon on the summer solstice.\n\nIf you were to trace the path of the sun from the horizon as it rises and sets--you might suffer permanent damage to your eyes, so don't--you would find that in North America the angle is more acute than it is in the tropics, because of the lower path in the sky.\n\nFor these two reasons, the sun spends more of its "day" near the horizon in the US than it would in many places in India. On the other hand, there are some places in the US that are farther south than some places in India!

I live in Alaska, so pay attention.  The earth is tilted; it doesn't spin at a right angle to the sun.  In summer, the north pole is tilted toward the sun, and as a result, the sun appears to circle the horizon, never actually setting.  In the winter, the opposite occurs.  The sun may peak over the southern horizon, but further north it never really rises.  In spring and fall, there is no difference from the rest of the U.S.

80 miles is not a significant variable to adjust for a difference in time of sunset.  The previous answers have stated curvature of the earth and referenced the tropics of Capricorn and cancer.  As of yet(when I started to answer) no one had brought up the incline plane of the Earths rotational axis.  It is due to the factors of the APPARENT position of the Sun, the curvature of the Earth and the Earths plane of rotational axis that we see 24 hours of daylight above the Antarctic and Arctic circles during specific times of the year.  \nThe reason of the differences of time of sunset would be a combination of plane of rotational axis, curvature of the Earth, and the time of year.  I seem to recall the 80 surface miles on the earth are equivalent to 1.526 degree of the apparent viewing depending where those 80 miles are.  as you get closer to the poles they would amount for a greater percentage of viewing angle.  \nAs to the temp difference where the towns are, latitude would effect a great deal of difference in the temperature, you need to give more finite guidelines if you want the specific reasons.

It's the angle of the earth's rotation.  The northern hemisphere tilts away from the sun during winter, causing long periods of darkness, and towards the sun in summer, causing longer daylight hours.  At the extreme nothern latitudes, this leads to constant daylight or constant darkness at those times of the year.

One of the major reasons given for observing DST is energy conservation. Theoretically, the amount of residential electricity needed in the evening hours is dependent both on when the sun sets and when people go to bed. Because people tend to observe the same bedtime year-round, by artificially moving sunset one hour later, the amount of energy used is theoretically reduced. United States Department of Transportation studies showed that DST reduces the country's electricity usage by one percent while DST is in effect.

The Sun, in its seasonal movement through the sky, passes directly over the equator twice each year on the Vernal and Autumnal Equinoxes, which occur in March and September (respectively). At the equator, the rays of the sun are perpendicular to the surface of the earth on these dates.\n\nPlaces near the equator experience the quickest rates of sunrise and sunset in the world, taking minutes. Such places also have a relatively constant amount of day/night time on every day throughout the year compared with more northerly or southerly places.

you also need your latitude.  \n\nThink about it, if you were at one of the poles, sun-rise and sunset would be drastically different.\n\nYes, There is a formula.\n\nHere's the answer in positional astronomy...

That depends on what side you are on. One side is always daytime the other side is always nighttime.

The sun or moon is actually below the horizon and the atmosphere is acting as a lens to refract the light and magnify the object. The higher the angle, the less refraction. It has zero to do with comparison of objects on the horizon.

As the light from the sun enters the atmosphere, the atmosphere bends it a certain amount. Because the sun is closer to the horizon at sunrise and sunset, there is more atmosphere to bend the incoming light rays. Hence, the sun appears larger at sunrise and sunset because of atmospheric lensing.

I believe you are referring to the changes in the seasons.  Because the rotational axis of the earth is tilted a bit more than 23 degrees away from it's orbital plane the earth gets a bit more in the way of the sun (so to speak) as winter approaches so sunrise is a bit later each day, and sunset a bit earlier.  After the winter solstice less and less of the earth is in the way, so sunrise starts a bit earlier each day, and sunset a bit later, until the summer solstice.  Interestingly dusk is longer in the winter because the sun rises and sets at more of an angle to the horizon.  For the same reason, in the tropics dusk is shorter because the sun rises and sets more nearly vertical.  In the more northern part of the northern hemisphere and the more southern part of the southern hemisphere dusk may last all night long in the summer (culminating in the "midnight sun" north of the arctic or south of the antarctic circles).  In addition, due to the refraction of the atmosphere we see the sun earlier than actual sunrise and later than actual sunset (the atmosphere acts as sort of a lens).

Also, we only see it when it is above the horizon.\n\nDuring the day, the sun is obviously above the horizon.  But the moon sets an hour or so later each day, so sometimes it is below the horizon in the day, and sometimes not.

at different times on the earth the sun is at different positions in the sky. When it's noon somewhere, it's midnight on the direct opposite side of the earth. If a particular time was called 12 noon to everyone it would seem silly to the people where it was midnight.

Because when the sun is up in korea, it can't be in the sky at the same time in england.  So when it is noon in korea, it's around midnight in england.  When the sun is coming up in korea (the sun comes up in the east) it is still 3 hours from coming up in india.  Since midnight is the beginning of a new day, the date is different as well.

You did meant to say "months" twice, right?  Because moths and months are slightly different things.\n\nAnyway, the difference is caused by how close the earth is to the sun (during its orbit around the sun.)  When the earth spins each day, it turns from day to night because the earth is facing the sun for half of the turn (roughly) and facing away for the other half (causing day and night.)  But depending on the orbit, the sun hits the earth differently.\n\nThe sun in fall and winter is more direct, I mean, like it hits you in the face.  It's, um, slanted differently.  But the light is weaker since the part of the earth that's having cold weather is tilted further from the sun.  Did I mention that the earth is tilted?  So that way, one hemisphere is tilted closer to the sun during one side of the orbit, and the other hemisphere gets the seasons during the opposite time of year (other side of the orbit.)  \n\nOK, like imagine that this percent mark % represents the northern and southern hemispheres.  Imagine that the % mark is traveling in a circle around a central sphere.  So on one side of the circle, the upper 0 is tilted toward the sun (spring and summer) and the lower 0 is on the other side of the tilted line and it's further from the sun.  But when the % gets to the other side of the circle, the *upper* 0 is on the far side of the tilted line and then the *lower* 0 is closer to the sun.  Which gives you seasons.\n\nI guess it gets lighter and darker faster because there's less clouds in fall and winter (it's colder, so there's less smog and haze and cloud cover in general) so dawn and dusk seem to happen faster.  Plus, there's less light and heat in general.  \n\nI hope that made sense.  The % thing makes sense to me, but if it doesn't, then make yourself a 3D model and see if it makes sense.

One question at a time.\n\nThe first one has been answered. Becasue of the earths tilt, countries in the southern hemisphere are closer to the sun in December than the countries in the northern hemisphere - that is why we have winer here (its further away). And when the earth goes around to the other side of its orbit around the sun in July, we in the northern hemisphere are closer, while they are farther. \n\nThis the general rule, however there are many other factors like elevation, precipitation, wind patterns, jet streams, ocean currents etc etc. so yes - every country in the northern hemisphere it is officially summer in july etc. but not necessarily as warm as some other countries can get. and vice versa for the southern hemisphere of course.\n\nAll of us - when we stand up, we are perpendicular to the earths surface no matter where we are. Imagine a ball ... and pins sticking straight out of the ball. This is how we'd look, so to a person on the south POLE, would be upside down to someone on the north POLE. or someone in one area, will be upside to someone else DIRECTLY on the other side the earth's surface. Everyone else will be in varying degrees of "upsidedownness"\n\nDaylight savings time is a pure man made concept. But again ... because of the tilt of the earth, during July etc. the sun shines longer on the northern hemisphere (The days are longer) and the southern hemisphere the days are shorter. This causes the sun to rise earlier and earlier and then after the longest day of the year, it reverses - the days get shorter and shorter. \n\nNow what happens is that you can wake up at 6 am and it still be pitch dark and 7 am it starts to rise and 8 am its fully light. So they change the time to go an hour back (Fall Back) and this allows the time now to be 5 am as pitch dark, 6 am start rise, and 7 am fully light. So for people who wake up at 7 am everyday, the first plan it will be kinda  dark when they wake up but with daylight savings, it will be fully light when they wake up! Thus its just something certain countries do to be able to have light for when most people wake up in the morning - even if you are not a mornig person - about 90% of people wake up at that time to to go to work\n\nHope all this made sense and email me at alxsml@yahoo.com for more clarification.

cause in Ur position the sun is not completely vertical , in which all times the vertical rays have the greater effect , so we will tilt it in a degree to make the rays vertical approximately to Ur panel
