Question
Which visible motion can be explained by a geocentric model?
- Movement of a Foucault pendulum
- Deflection of the wind
- Curved way of projectiles
- The Sun's way through the sky
Hint:
Earlier people used to believe in the geocentric model of our solar system.
The correct answer is: The Sun's way through the sky
- In astronomy, the geocentric model is a superseded description of the Universe with Earth at the center.
- Under most geocentric models, the Sun, Moon, stars, and planets all orbit Earth.
- The Foucault Pendulum is named for the French physicist Jean Foucault (pronounced "Foo-koh), who first used it in 1851 to demonstrate the rotation of the earth. It was the first satisfactory demonstration of the earth's rotation using laboratory apparatus rather than astronomical observations
- So option A is correct
