The air temperature actually doesn't get lower because of approaching towards the sun.
The concept behind this is that, the atmosphere on earth traps the heat from the solar radiations. This is what we call as 'Greenhouse effect'. This occurs because the carbon dioxide in the atmosphere stops the heat reflected from the earth to go back into space, upto some extent. Without the greenhouse effect, the temperature at the equator would be 16
When the Earth is at its perihelion - when it is closest to the sun - the Northern hemisphere is experiencing winter, while the Southern Hemisphere is experiencing summer. The Earth, as a whole, isn't actually colder during the perihelion. The cooler temperatures in the Northern hemisphere during this point along the Earth's orbit around the sun has more to do with the tilt of the Earth's axis rather than its distance from the sun. As such, when the Earth is at its aphelion - when it is furthest from the sun - the Northern hemisphere is experiencing summer and the Southern hemisphere is experiencing winter.
During the winter solstice - which occurs about two weeks prior to the Earth's perihelion - the Earth's Northern hemisphere is tilted away from the sun, and experiences the shortest day of the year. Due to the reduction in the amount of daylight hours, temperatures in the Northern hemisphere are lower compared to when its the summer solstice (when the Northern hemisphere experiences the longest day of the year).
Air is an ideal gas, therefore pressure and temperature are directly related. The following equation, describes how air and Temperature relate to one another for air.
P1/T1 = P2/T2 or
T2 = P2/P1 * T1
where 1 describes height 1 and
2 describes height 2.
P is pressure and T is temperature.
as the distance from the earth increases (height), pressure decreases. As a result, temperature decreases as well.
ex: Lets say H2 > H1, and P2 = 1 Pa (Pascal "Pa" is the unit for pressure) and P1 = 2 Pa. The temperature at H1 is T1 = 50 C. What is the temperature at H2?
T2 = P2/P1 *T1 = 1/2 * 50 = 25 C.
The temperature does not drop as you approach the sun. There is a region around the sun known as the chromosphere which is about 25,000 K, while the photosphere beneath it is only 4000 K. This temperature difference may be explained by "magnetic reconnection."
But in general, solar electromagnetic radiation (including light and heat) increase with the square of the reciprocal of the distance between you and the sun. Within the sun itself the temperature gradient increases as one approaches the core.

But as we advance upwards in the atmosphere, the concentration of CO2 lowers. As a result, less heat is trapped in the upper part of the atmosphere and as a result, less temperature is observed. The air temperature actually doesn't get lower because of approaching towards the sun.

The lower atmosphere is heated by the ground.

Yes, the sun is slightly closer to the earth in the winter. It is colder because the slant of the earth's axis is away from the sun.
yeah, its closer to the sun so its warmer when its nearly circular then its colder
false.
No, Venus is closer to the Sun than the Earth.
the moon gets farther and closer to the sun than the earth because as you should know the planets roatate and when the moon of the earth is directed at the sun it is hotter than the earth because it is closer to the moon. and when the moon is on the oppsite side it is colder than the earth because the sun is farther away than the earth.

because the earth is closer to the sun at some points of the year :)
The farther the sun gets away from the earth, the colder it is, that is WInter and Fall. The closer it gets the warmer it gets. That is Spring and Summer.

because of the way the earth moves. when your top or bottom half of the world is closer to the sun, it is warmer. the further it is from the sun, the colder it is. I'm estimating you're in the northern hemisphere, so it is closer to the sun during June and further away from the sun in January.
no the earth is closer to the sun that Uranus
the earth revolves around the sun and as each part of earth turns closer or farther the earth gets warmer or colder creating seasons.
there are so many seasons because as the earth gets closer to the sun, the temperature changes as it gets warmer, but when the earth get farther away from the sun, the temperature starts to change as it gets colder.
false.
The farther the sun gets away from the earth, the colder it is, that is WInter and Fall. The closer it gets the warmer it gets. That is Spring and Summer.
Earth is closer to the sun
The seasons are caused by the tilt of the earth relative to the sun. The earths axis is tilted and not perfectly parallel with the sun's axis. This means that as the earth circles the sun half the planet will be closer to the sun then the other. When half is closer that is summer. (closer = hotter). When it is farthest away that is winter (father = colder). Spring and fall are the transition times in between. When the tilt is moving away from the sun it is getting farther and farther away and getting colder...(fall). When it gets closer then it gets warmer leading to spring. Food for thought....when its summer in the USA..its winter in Australia
