1 Astronomy 1 Fall 2016 Announcements: 1. Midterm exam on Thursday (in this room) 2. Oct 21 st - 26 th : Sections replaced by evening observing) Lecture 8: October 18, 2016
2 Previously on Astro 1 Solar System Formation: the nebular hypothesis. The Sun: formed by gravitational contraction of the center of the nebula. Terrestrial planets: formed through accretion of dust particles into planetesimals, then into larger protoplanets. Jovian planets: Began as rocky protoplanetary cores, similar in character to the terrestrial planets. Gas then accreted onto these cores. Alternatively, they formed directly from the gases of the solar nebula. In this model the cores formed from planetesimals falling into the planets.
3 Today on Astro 1 What does the Moon look like? What is the Moon made of? How did the Moon form? Also, tidal forces What they are Affect on Earth Affect on Moon

6 The Moon s Rotation and Libration Wobbles back and forth due to the elliptical shape of its orbit. Nods up and down because rotation axis is not exactly perpendicular to its orbit.
7 The Moon Appears to Wobble & Nod
8 How Well Do You Know the Moon?

The Earth would rise and set once a lunar month, but the Sun would not appear to move significantly in the lunar sky. C. The Earth would not appear to move significantly in the lunar sky, and the Sun would rise and set once a lunar month. D. The Earth and Sun would not appear to move significantly in the lunar sky. E. None of these answers are correct. Q10.2

11 The astronaut footprint on the Moon shown in this photograph will probably A. exist for >10,000 years because there is very little weathering on the Moon. B. exist for >10,000 years because the Moon s surface is hard and durable. C. exist for <10,000 years due to erosion from wind in the tenuous lunar atmosphere. D. exist for <10,000 years due to bombardment by large numbers of meteors. E. Both C and D are correct. Q10.1

D. exist for <10,000 years due to bombardment by large numbers of meteors. E. Both C and D are correct. A10.1
13 The large flat plains on the Moon are called maria. The maria were formed A. in old sea beds. B. when large meteors hit the Moon and flattened its surface.

E. by tidal interactions between the Earth and Moon. A10.3
15 Some areas of the Moon are relatively smooth, whereas other areas are heavily cratered. This is because A. meteors did not strike the flat areas because they are in the Earth s shadow. B. weathering has smoothed parts of the Moon. C. plate tectonics has recycled parts of the lunar crust. D. in some places lava flows have covered over older craters, leaving a smoother surface. E. tidal forces between the Earth and Moon smoothed parts of the Moon. Q10.4

61 Summary The moon s surface has very old rocks in the highlands and much younger rock in the maria. The far side of the moon has a thicker crust & few maria. Heavily cratered surface indicates no plate tectonics Late Heavy Bombardment formed the maria basins 4.1 to 3.8 Gyr ago which were later filled by lava. Meteoroids and solar wind weather the surface. Collisional ejection theory for the Moon s origin Early moon was molten Formed from debris of proto-planet & Earth collision Tidal interactions of Earth and the Moon Slow Earth s rotation Push the Moon further away
