Solar eclipses can happen only near New Moon. True False

2. IQ • Solar eclipses can happen only near New Moon. • True • False

3. IQ • True. New Moon is the correct answer! • A solar eclipse occurs when the Sun is blocked by the Moon. This can only happen when the moon is between the Earth and the Sun, which is New Moon.

4. IQ • Lunar eclipses can only happen at: • A. New Moon • B. First quarter • C. Full Moon • D. Third quarter

5. IQ • C. Full Moon is correct. • A lunar eclipse occurs when the Earth blocks the Sun’s light from the Moon. This can only happen when the Moon is opposite the Sun as seen from the Earth - that is, the Earth is between the Sun and Moon. That happens only at Full Moon!

9. IQ • The Full Moon always rises at: • A. Midnight • B. Sunset • C. Sunrise • D. It is always in the sky

10. IQ • B. Sunset is correct. • The phases of the moon refer to the pattern of illumination on the hemisphere facing Earth. Full Moon occurs when the entire hemisphere is illuminated, which can only occur when the Moon is directly opposite the Sun as seen from the Earth. The full moon must rise just as the sun sets.

14. IQ • Polaris (the North Star) just happens to be near the Earth’s rotation axis. • T • F

19. IQ • Astrology is a science. • True • False

20. IQ • False is the correct answer. • Astrology does not use the scientific method to verify its techniques and predictions. Principally because of the Earth’s precession, the constellations and sky signs of astrology no longer match the true positions of astronomical objects.
