Question

which of the following is true for a lunar eclipse? the moon is casting a shadow on the earth. the sun is casting a shadow on the moon. the earth is casting a shadow on the sun. the earth is casting a shadow on the moon.

Explanation:

A lunar eclipse occurs when the Earth comes between the Sun and the Moon, and the Earth's shadow falls on the Moon. Let's analyze each option:

• "The moon is casting a shadow on the Earth" describes a solar eclipse (when the Moon is between the Sun and Earth, casting a shadow on Earth).
• "The sun is casting a shadow on the moon" is incorrect as shadows are formed by an object blocking light, and the Sun itself doesn't cast a shadow on the Moon in this context.
• "The Earth is casting a shadow on the sun" is impossible as the Earth is much smaller than the Sun and can't cast a shadow on it.
• "The Earth is casting a shadow on the moon" is correct as during a lunar eclipse, Earth is between the Sun and Moon, so Earth's shadow falls on the Moon.

Answer:

The Earth is casting a shadow on the moon.
