The past civilizations’ understanding of astronomy.

Answer to Problem 1Q
The structures made by the ancient civilizations such as Stonehenge in America, Egyptian Pyramids helps in the understanding of astronomy.
Explanation of Solution
Introduction:
Astronomy is the oldest science which studies about different celestial objects like stars, planets, comets, etc.
Calenders are also determined by position of Sun and moon.
For ancient people, astronomy helps to identify the changes of seasons, to make calendar and time tracking devices.
Stone structures developed by British residents stated about the location of the sun and key times during year.
Puebloans make use of illumination of stone carving from the sun on the first day of summer or winter to define seasons.
Incans of Machu Picchu used window carving to define sunrise on 21st December each year.
Thus, three structures made by the past civilizations helps in the understanding of astronomy are givenas follows:
- Stonehenge in America from Southwestern United States to Andes of Peru.
- Grad tomb of Shih Ti the first emperor of China also helps in the understanding of astronomy.
- The great Egyptian Pyramids oriented north-south and east-west has an accuracy more than one degree.
