Question

5. Answer the following.
(1) Why do the sun, the moon and the earth
not lie in one and the same line on every
full moon and new moon day?​

Answer 1

Answer:

Answer. Because the Earth and Moon don't orbit in the same plane. The Earth is inclined in its orbit of the Sun, and the Moon is inclined in it's orbit of the Earth. ... When the Moon crosses this point while the two lines are close enough to parallel, we get eclipses.

Answer 2

Answer:

Bottom line: There's no eclipse at every full moon and new moon because the moon's orbit is inclined to Earth's orbit by about five degrees. Most of the time, the sun, Earth and moon don't line up precisely enough to cause an eclipse.
