Chapter 3, Problem 1QQ

Choose the best answer to each of the following. Explain your reasoning.

A geocentric model of the universe is (a) any model that places Earth at the centre of the universe. (b) any model that has Earth as a planet orbiting the Sun. (c) any model that places the Sun at the center of the universe.

Expert Solution & Answer
Check Mark
To determine

The geocentric model.

Answer to Problem 1QQ

The correct answer is (a).

Explanation of Solution

Introduction:

Geocentric model was first created by Aristotle. Then, Ptolemy who is a Greek astronomer gives the detailed explanation about the geocentric model.

The geocentric model is developed by the ancient Greeks. Rendering to this, the earth is at the center of the universe and all the planets and Sun revolves around the Earth in a specific orbit.

Therefore, the answer is an option (a).

According to this model, the center of the universe is the Earth and the Sun and the other planets revolve around it. So, option (b) is incorrect.

Unlike in the geocentric model, in the heliocentric model, the Sun is placed at the center of the universe. So, option (c) is incorrect.

Conclusion:

Therefore, the correct answer is (a).
