Question

base your answers to questions 44 and 45 on the diagram below and on your knowledge of earth science. the diagram represents the moon at four positions, labeled a, b, c, and d, in its orbit around earth. the position full-moon phase is labeled. 44. the same side of the moon always faces earth because the moons period of revolution a) equals the moons period of rotation b) equals earths period of rotation c) is longer than earths period of rotation d) is longer than the moons period of rotation 45. solar and lunar eclipses rarely happen during a cycle of phases because the a) plane of the moons orbit is the same as the plane of earths orbit b) moons orbit is circular and earths orbit is elliptical c) moons orbit is elliptical and earths orbit is elliptical d) plane of the moons orbit is different from the plane of earths orbit

Explanation:

• Question 44:
• The Moon rotates on its axis (period of rotation) and revolves around the Earth (period of revolution).
• When these two periods are equal, the same side of the Moon always faces the Earth.
• Question 45:
• Solar eclipses occur when the Moon is between the Sun and the Earth, and lunar eclipses occur when the Earth is between the Sun and the Moon.
• These events are rare because the plane of the Moon's orbit is different from the plane of Earth's orbit.

Answer:

1. A. equals the Moon's period of rotation
2. D. plane of the Moon's orbit is different from the plane of Earth's orbit
