Which term describes the model where Earth is at the center of the universe?

• A. Geocentric theory
• B. Heliocentric theory
• C. Scientific Method
• D. Scientific Revolution

Answer: (A)

The term describes a model in which Earth sits at the center of the universe, with the Sun, Moon, planets, and stars orbiting around it. This geocentric view was the dominant explanation for how the heavens appeared to move, and it was reinforced by the observed daily motion of the Sun and stars and by the attempt to account for the complex planetary paths using deferents and epicycles. In this framework, Earth is fixed in place, and celestial motions are built around that central point. A different idea places the Sun at the center (the heliocentric theory), which eventually explained planetary motions more simply and accounted for retrograde motion as an observational effect from moving planets around the Sun. The scientific method refers to a way of investigating phenomena and testing ideas, not a model of the cosmos. The Scientific Revolution refers to the historical shift in thinking that brought about new methods and understandings in science, not a specific cosmological arrangement.
