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.

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.

the answer is 95 degrees
