Question

1. the diagrams represent the paths of solar noon positions of the sun on specific dates at four different earth locations.

four diagrams of solar noon positions at different locations
why does the position of the sun change throughout the year?

1. the earth has an axial tilt of 23.5°, whereas the planet mercury has a tilt of 0.03°. would

Explanation:

The change in the Sun's position throughout the year is due to the Earth's axial tilt (23.5°) and its revolution around the Sun. As Earth orbits the Sun, the tilt causes different latitudes to receive varying amounts of solar radiation, leading to seasonal changes and shifts in solar noon positions. The Earth’s orbit is elliptical, but the tilt (and resulting solar angle changes) is the primary reason for the Sun’s apparent position changes over the year.

Answer:

The position of the Sun changes throughout the year because the Earth has an axial tilt of 23.5° and revolves around the Sun. This tilt causes different parts of the Earth to receive varying amounts of solar radiation as the Earth orbits the Sun, leading to seasonal changes and shifts in the Sun's apparent position (including solar noon positions) at a given location.
