Which statements about the geocentric model are false? Select the two correct answers.(2 points)

The two false statements about the geocentric model are:

1. **It shows the Sun at the center of the solar system.**
(This statement is false because the geocentric model places the Earth at the center, not the Sun.)

2. **It explains why Mars appears to move backward for a few months approximately every two years.**
(While the geocentric model attempts to explain retrograde motion, it does not accurately do so. The understanding of retrograde motion is better explained by the heliocentric model, which accounts for the relative motion of Earth and Mars.)

The true statement is:

- **It shows Earth at the center of the solar system.**
- **It shows the orbits of the planets as circular.** (This is true as the geocentric model often represented planetary orbits as circular.)
