Total and partial eclipses of the Moon

                        The diagram below shows the stages of the eclipse of the Moon that can
                        be seen with the naked eye. In these stages, we can see two types of
                        eclipse of the Moon, namely the total eclipse of the Moon and the partial
                        eclipse of the Moon. How do the stages of the eclipse of the Moon occur?
