During a total lunar eclipse, the earth, sun, and moon are arranged in a line, and the moon is completely dark. in what order do the earth, sun, and moon line up?

The Earth lies between the Sun and the Moon.

Explanation:

During a total lunar eclipse, the Sun, the Earth and the moon align in such a way that the earth blocks the sunlight to fall on moon and moon passes through Earth's shadow.

The arrangement is: Sun then Earth then Moon.

Total lunar eclipse does not occur on every full moon night because the there is a slight difference in the alignment of orbits.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
