Respuesta :
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 (in "syzygy") exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can occur only the night of a full moon.
Answer: d. full moon
Explanation:
Lunar eclipse occurs when Earth comes between Sun and Moon. Moon does not have its own light and reflects the light of the Sun. When Earth comes between the moon and the Sun, it blocks the sunlight falling on Moon. Thus, the moon appears dark as Earth's shadow falls on it. This arrangement is of Earth between Sun and moon causes full moon phase.
