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.

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.)
At 5 AM the temperature was 15 degrees below zero By noon it had risen to 13 degrees What was the average hourly increase in temperature?
The temperature increased by 28 degrees from 5 AM to noon (15 degrees below zero to 13 degrees). This change occurred over 7 hours (5 AM to noon). Therefore, the average hourly increase in temperature was 28 degrees / 7 hours = 4 degrees per hour.
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.
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?
If The altitude of polaris is 45 and your local noon occurs at 7pm greenwhich time what is your position?
Your position is 45 degrees latitude north. The altitude of Polaris (the North Star) corresponds to your latitude in the Northern Hemisphere. Since your local noon occurs at 7pm Greenwich Mean Time, you are located in the time zone that is 5 hours behind GMT, such as Eastern Standard Time in the USA.
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 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 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 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.
On march 4th 1873 the morning temperature was -2 degrees farhenhiet by noon it was warmer how many degrees had the temperature risen?
The temperature had risen from -2 degrees Fahrenheit in the morning to a warmer temperature by noon. The exact number of degrees it had risen would depend on the new temperature at noon.
What causes the sun to be higher in the sky at noon in the summer?
The sun is higher in the sky at noon in the summer due to the tilt of the Earth's axis. During summer in the Northern Hemisphere, the North Pole is tilted toward the sun, resulting in longer days and a higher sun angle. This angle causes the sun to reach its peak point in the sky at noon during the summer months.
How many degrees will it be latter in the after noon?
70 and up +
At 5 AM the temperature was 15 degrees below zero By noon it had risen to 13 degrees What was the average hourly increase in temperature?
The temperature increased by 28 degrees from 5 AM to noon (15 degrees below zero to 13 degrees). This change occurred over 7 hours (5 AM to noon). Therefore, the average hourly increase in temperature was 28 degrees / 7 hours = 4 degrees per hour.
The noon temperature for the warmest January inauguration was degrees Fahrenheit?
70 degrees... wow!
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.
From latitude 35 what is the highest altitude above the noon sun?
For an observer at latitude 35 degrees, the highest the sun can ever be in his sky is roughly 31.5 degrees above the horizon.
Where will be the sun at noon?
The sun will be directly overhead at noon for locations along the Tropic of Cancer (23.5 degrees north latitude) on the June solstice and locations along the Tropic of Capricorn (23.5 degrees south latitude) on the December solstice. In between those latitudes, the sun will be high in the sky but not directly overhead at noon.
