The variation with altitude is approximately linear, and so we conclude that sunset is later by 1 minute for every 1.5 kilometres in altitude, and that sunrise is earlier by the same amount.
Does altitude affect sunset time?
An easy way to determine what effect altitude has is to remember than sunrise will be one minute earlier for every mile of altitude, and that sunset will be later by the same amount.
Does the sun set later at higher latitudes?
The sun always sets faster near Earths equator and more slowly at higher latitudes. However, at that latitude, the solstice sun sets in roughly 3 1/4 minutes. At a solstice, the sun is setting farthest north or farthest south of due west.
Is sunset later at the top of a mountain?
If you were observing from the top of a tall mountain, sunrise would happen slightly earlier, and sunset slightly later. But it would be a small correction — only about 6 minutes if observing from the top of Mt. Everest. Say you have a large mountain on your horizon that is elevated 10° above the horizon.
Does elevation affect day length?
At most latitudes on the Earth, the effect of increased altitude is the same: it makes the Sun rise earlier and set later than it would at that same location from the ground. ...
Why does the sunset at different times in the same time zone?
The combination of Earths elliptical orbit and the tilt of its axis results in the Sun taking different paths across the sky at slightly different speeds each day. This gives us different sunrise and sunset times each day.
How does the suns altitude affect shadow length?
The position of the sun affects the size of a shadow. A person or object blocks more light when the sun is low in the sky. Less light is blocked when the sun is high in the sky. This makes shadows shorter.
Why does the sunset so early in Denver?
The reason why this week is home to the earliest sunsets of the year is due to the solar noon, or the exact time of the suns highest point in the sky. The solar noon gets later in the day in December, despite the days themselves shortening until the winter solstice on the Dec. 21.
