I only need the answers for 7 and 8! No need to write a sentence on what it’s about. ( sorry if the picture is small) thank you <3

question 7,  MOON ECLIPSE

question 8, SUM ECLIPSE

Explanation:

We call an eclipse when a celestial body is interposed between the sun and another body.

In all the case of question 7, the Earth is interposed between the moon and the Sun, which is why it is called MOON ECLIPSE

In the case of question 8, the Moon stands between the sun and the Earth and is called the SUM ECLIPSE .
