Eli5: Equation of time

235 views

I get that this is made up of two components.

One part is because the Earth is elliptical and one part is because of the tilt.

The elliptical effect on difference between solar noon and clock noon I get.

However, I have not been able to work out why the tilt of the axis causes a difference between solar noon and clock noon and if anyone can explain it to me that would be great, tyia

Time Zones.

Your location relative to that time zone Solar Noon will determine The sun’s relative location to your Clock Noon

The tilt of the Earth’s axis causes a difference between solar noon and clock noon because the angle at which the sun’s rays hit the Earth’s surface changes throughout the year. This means that the amount of daylight received at a particular location also changes throughout the year.

When the Earth is tilted towards the sun, the sun’s rays hit the Earth’s surface at a more direct angle, resulting in longer days and shorter nights. This is known as the summer solstice. On the other hand, when the Earth is tilted away from the sun, the sun’s rays hit the Earth’s surface at a less direct angle, resulting in shorter days and longer nights. This is known as the winter solstice.

The changing angle at which the sun’s rays hit the Earth’s surface throughout the year results in a difference between solar noon and clock noon. Solar noon is the time when the sun is at its highest point in the sky, and it occurs at a different time each day due to the changing angle of the sun’s rays. Clock noon, on the other hand, is the time when the clock says it is noon, and it remains constant throughout the year.

TLDR; the tilt of the Earth’s axis causes a difference between solar noon and clock noon because it results in changes in the angle at which the sun’s rays hit the Earth’s surface, and therefore changes in the amount of daylight received at a particular location.
