Question

For a lunar eclipse to occur, the sun, earth and the moon have to come in a straight line with the earth in the middle.

• A. True
• B. False

Answer 1

The correct option is A True

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth, and moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can occur only the night of a full moon.

The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes.A total lunar eclipse has the direct sunlight completely blocked by the earth's shadow. The only light seen is refracted through the earth's shadow.
