Question

According to the model developed by Copernicus, what causes day and night on Earth?

A
Earth rotates on its axis.

B
Planets orbit the sun in elliptical paths.

C
All parts of the solar system move in circular paths.

D
Earth revolves around the sun.

Answer 1

A IS THE RIGHT ANSWER

Answer 2

It is the Earth that orbits around the Sun, as the Heliocentric Theory (Helios = Sun) of Copernicus said.

The Sun does not "come out" or "set": in reality it is the Earth that, by turning or rotating on its own axis, causes day and night.

The answer is: A. Earth rotates on its axis.
