To determine which diagram represents when a full moon would be observed from Earth's surface, we need to understand the positioning of the Sun, Earth, and Moon during a full moon.
A full moon occurs when the Earth is positioned between the Sun and the Moon. In this alignment:
- The Sun (A) should be on one side.
- The Earth (B) will be in the middle.
- The Moon (C) will be on the opposite side of the Earth from the Sun.
When looking for the correct diagram, you want to find one where the Moon is directly opposite the Sun with the Earth in between.
Please provide the diagrams or describe them so I can help you identify which one correctly represents a full moon.
