September 24, 2021 | education
| The Earth revolves around the Sun in an elliptical orbit, making one complete revolution per year. The angle of inclination of the earth’s axis to the orbital plane is 66.5 °, so there is a change of seasons on the earth. This also determines the apparent movement of the sun in the sky, its dependence on the time of year: the points of sunrise and sunset, its midday height change throughout the year. On the days of the equinox, the midday height h = 90 ° – φ, where φ is the latitude of the area. In winter, this height gradually decreases, reaching a minimum on the day of the winter solstice, and in summer, on the contrary, it increases and reaches a maximum on the day of the summer solstice.
