6. The angle of parallax increases as Question 10 a)distances to stars increase. b)the baseline gets larger. c) the baseline gets smaller. d) the Earth moves faster in its orbit.

7. a)distances to stars increase. b)the baseline gets larger. c) the baseline gets smaller. d) the Earth moves faster in its orbit. The angle of parallax increases as Question 10 The greater the distance between two observation points (the baseline), the larger the angle of parallax.

9. a)the same phase in 24 hours. b)different phases in 24 hours. c) a lunar eclipse once a month. d) different sides of the Moon. Considering the Moon’s phases, everyone on Earth sees Question 12

10. a)the same phase in 24 hours. b)different phases in 24 hours. c) a lunar eclipse once a month. d) different sides of the Moon. Considering the Moon’s phases, everyone on Earth sees Question 12 The Moon goes through its cycle of phases in about 30 days; the Earth rotates once in only 24 hours. So everyone has a chance to see the same phase!
