What causes the position of the noon sun to vary by up to 47 degrees over a year's time?

The axial tilt of the earth is 23 and a half degrees, two times this is 47 degrees.
The tilt will remain constant but as the earth rotates about the sun, the sun will get higher and lower in at noon depending on the time of year.
At the equinox, around March 21rst, the length of day is about the same as the length of night. the position of the earth about the sun means that the tilt is neither away or towards the sun.
The tilt of 23 and a half degrees becomes apparent (for the northern hemisphere) at the summer solstice (Around June 21st), when the tilt towards the sun gives the longest day, and the highest sun at noon. Then we have another equinox around Sept 21st, where the tilt has no effect (sun is at average height). Finally, we have the Winter solstice (around Dec 21st), when the tilt of the earth is away from the sun, to cause the shortest day and the lowest sun height.
So we go from 0, to +23.5, back to 0 then to -23.5, which is reflected by the suns height at mid day.

∙ 13y agoThe Earth's axis of rotation is tilted with respect to the plane of the Earth's orbit around the Sun. So as the Earth travels around the Sun, the Sun appears to travel between the Tropic of Cancer, at 23.5 degrees north latitude, and the Tropic of Capricorn, at 23.5 degrees south.

When it is noon at prime meridian on the equator what is the time at 55 degrees north latitude on this same meridian?
noon
What is the position of the sun at summer equinox if you are at thirty degrees north and ninety one degrees west?
At Local Apparent Noon, when the Sun is highest in the sky, it would reach an elevation of about 83.5 degrees. (Your longitude doesn't matter, unless you need to specify a precise day and time.)
What is the solar time of 110 degrees east longitude if it is noon solar time at 70 degrees west longitude?
70W is 180 degrees away from 110E, so if it's noon at 70W, it's midnight at 110E.
What is the solar time of 72 degrees W longitude if it is noon solar time at 70 degrees W longitude?
Since the degrees here are 2 more than the original 70 degrees, and each degree going W equals 4 minutes; if you start at noon, and you multiply (2) degrees by (4) minutes, then you get 8 minutes, which you add to the original time of (noon). You answer is 12:08 p.m.
When it is noon at a point on a meridian it is 2 hours earlier 30 to the west of the meridian?
The missing word is "degrees".When it is noon at a point on a meridian it is 2 hours earlier 30 degrees to the west of the meridian?
What causes the position of the noon sun to vary by as much as 47 degrees over a years time?
That is related by the inclination of Earth's axis (compared to a line that is perpendicular to the Ecliptic - Earth's plane of orbit).47 degrees is twice this inclination. At noon, the Sun can go up to 23.5 degrees north and south of the central position (the position at the time of the equinoxes). For example, for an observer at the equator, at noon the Sun could go up to 23.5 degrees north or south of the zenith.
What causes the sun to be higher in the sky at noon in the summer?
The motions of the earth in its orbit of the Sun are kind of like a wobbling spinning top. This causes the Sun's noon position to appear to change over the seasons.
What is a 12 noon temperature of 50 degrees Fahrenheit?
At noon the temperature is 50 degrees Fahrenheit. It can get warmer as the day goes on.
What is the difference between the position of the sun at midday on a winters day and midday on a summers day?
At high noon on a winter's day, the sun is about 23 degrees below the equator. At high noon on a summer's day, the sun is about 23 degrees above the horizon. Because the earth is tilted at a 23.5 degree angle, the sun appears to be at that angle across the sky. The difference between the position of the sun during these two seasons is 47 degrees.
When it is noon at prime meridian on the equator what is the time at 55 degrees north latitude on this same meridian?
noon
What is the name given to the sun's position at noon?
At noon the Sun is at its "zenith". The highest elevation it will reach that day.
How many degrees will it be latter in the after noon?
70 and up +
The noon temperature for the warmest January inauguration was degrees Fahrenheit?
70 degrees... wow!
What is the position of the sun at summer equinox if you are at thirty degrees north and ninety one degrees west?
At Local Apparent Noon, when the Sun is highest in the sky, it would reach an elevation of about 83.5 degrees. (Your longitude doesn't matter, unless you need to specify a precise day and time.)
What is the solar time of 110 degrees east longitude if it is noon solar time at 70 degrees west longitude?
70W is 180 degrees away from 110E, so if it's noon at 70W, it's midnight at 110E.
How much higher is the sun at noon compared to midnight at latitude 80 degrees north - on days where the sun never sets?
First, we need the "transit altitude" of the celestial equator, at 80 degrees north. That's 90 - 80 degrees = 10 degrees. At noon (local apparent noon) the Sun's altitude will be: 10 degrees + the Sun's declination. That's the altitude of the Sun's "upper culmination". At "midnight" (the Sun's "lower culmination") the Sun's altitude will be: the Sun's declination - 10 degrees. So, the difference in altitude is 20 degrees. The Sun is 20 degrees higher at noon.
