Question

What did you observe about the position of the sun at the horizon at the time of sunrise and sunset?

Answer 1

Hi,

Your answer :
During the Earth's annual revolution around the Sun, the inclination of the earth relative to the sun changes (see picture in example). During the June 21st solstice (summer solstice in the northern hemisphere and winter solstice in the southern hemisphere), the northern hemisphere is more inclined towards the Sun and receives most of the solar radiation. Six months later, on December 21, the Earth reaches the winter solstice (in the northern hemisphere and summer solstice in the southern hemisphere), when the southern hemisphere is inclined towards the Sun and receives the majority solar radiation.

This change of position of the Earth in relation to the Sun generates days / nights of different durations as well as the creation of the seasons.

Good bye :)

Answer 2

$\huge\mathfrak\red{Answer:-}$

At the horizon – at sunrise or sunset – varies with the time of year, and also your latitude. It’s most perceptible around the equinoxes and least so around the solstices. Also, the sun’s daily change of position along the horizon is greater the farther north or south you are from Earth’s equator.

Justification:-

The degree of the sun’s movement along the horizon depends on two things:

• the time of year

• latitude

The sun’s movement along your horizon – at sunrise or sunset – is most perceptible around the equinoxes and least perceptible around the solstices.

Also, the sun’s daily change of position along the horizon is greater the farther north or south you are from Earth’s equator.
