Download Moon Phases and more Study notes Astronomy in PDF only on Docsity! Moon Phases Base your answers to questions 1 through 4 on the diagram below, which shows positions of the Moon in its orbit and phases of the Moon as viewed from New York State. A) The Moon does not rotate as it revolves around Earth. B) The Moon’s period of rotation equals Earth’s period of rotation. C) The Moon’s period of rotation equals Earth’s period of revolution around the Sun. D) The Moon’s period of rotation equals the Moon’s period of revolution around Earth. 1. Which statement best explains why the same side of the Moon is viewed from Earth as the Moon goes through its phases? A) 7 d B) 15 d C) 29.5 d D) 365.26 d 2. Approximately how many days occur between the Moon’s first-quarter phase and the Moon’s last-quarter phase? A) new Moon B) first quarter C) full Moon D) last quarter 3. During which Moon phase might a solar eclipse be viewed on Earth? A) 0.017 B) 0.055 C) 0.386 D) 0.723 4. What is the eccentricity of the Moon’s orbit? A) Moon's orbit is tilted relative to the Earth's orbit B) new-moon phase is visible only at night C) night side of the Moon faces toward the Earth D) apparent diameter of the Moon is greatest during the new-moon phase 5. The new-moon phase occurs when the Moon is positioned between the Earth and the Sun. However, these positions do not always cause an eclipse (blocking) of the Sun because the Moon Phases 6. Base your answer to the following question on The diagram below represents the Sun’s rays striking Earth and the Moon. Numbers 1 through 4 represent positions of the Moon in its orbit around Earth. A) 1 and 3 B) 2 and 4 C) 3 and 2 D) 4 and 1 The highest tides on Earth occur when the Moon is in positions Base your answers to questions 7 through 11 on the diagram below, which represents the Moon orbiting Earth as viewed from space above the North Pole.
