Question

Heliocentric model suggests:

a) All planets' orbits are circular
b) Relative distances of planets
c) Earth rotates on its own axis
d) All of the above

Answer 1

The heliocentric model suggests that all planets' orbits are elliptical, the relative distances of planets from the Sun, and that Earth rotates on its own axis.

Step-by-step explanation:

The heliocentric model suggests d) All of the above.

The heliocentric model, proposed by Nicolaus Copernicus, states that the Sun is at the center of the solar system and all the planets, including Earth, orbit around it. This model explains several key features of the solar system:

1. All planets' orbits are elliptical, with the Sun at one focus. This means that their orbits are not perfectly circular, but rather elongated.
2. The relative distances of planets from the Sun. Copernicus found that the closer a planet is to the Sun, the faster it orbits, proving that the speed of a planet is related to its distance from the Sun.
3. Earth rotates on its own axis. Copernicus's model also included the idea that Earth rotates, which explains the daily cycle of day and night.
