Text Review Notes for Exam IV (Final Exam) - Geol 1346

Chapters 16-20 in your text (Seeds Horizons: Exploring the Universe) corresponding to Lessons 19-26 (videotape series) - see review for Final Exam from orientation materials and Study Guide for video telecourse. The videos supplement and demonstrate examples and specific ideas from the material presented in the text.

Things to note -

1. words in bold type
2. Summary and New Terms at the end of each chapter
3. Review questions at the end of each chapter
4. Problems at the end of each chapter
5. Make a table summarizing and contrasting significant information (size, length of day, surface characteristics, …) for each of the planets

1. Review Ch 9 on star formation (esp. sec 9.1: The Birth of Stars, sec 9.5: The Orion Nebula and sub-sections on formation of stars from molecular clouds and evolutionary track of star as it forms - note Fig 9-8)
2. See Fig 16-4 on discovery of planet orbiting 51 Pegasi and methods of discovery of planets
3. 2 classes of planets, terrestrial and Jovian planets and basic differences
4. Chemical composition and evolution of Solar Nebula - condensation sequence (Table 16-3)
5. Differentiation and early evolution of protoplanets

1. Note sec 17-1 on early development of the Earth - especially 4 stages in planetary evolution, use of seismic waves to describe the Earth's interior structure, and plate tectonics and mantle convection
2. Evolution of the Earth's atmosphere - why is the Earth's atmosphere different?
3. Characteristics of the Moon - kinds of rocks, origin, and evolution - explain significant features (density/internal structure, mare, origin, …)?
4. Mercury - significant surface features, inferred internal structure, spin-orbit coupling, … ?
5. Venus - significant surface features, inferred internal structure, spin-orbit coupling, atmosphere, (pay special attention to geologic provinces, reasons for lack of convection, inferred geologic history, etc)…?
6. Mars - - significant surface features, inferred internal structure, spin-orbit coupling, atmosphere, (pay special attention to geologic provinces and inferred geologic history, presence / lack of water, etc)…?

1. Note particular characteristics of all of these planets and their largest moons - be able to compare and contrast characteristics
2. Note significant features which are unique - e.g. presence of tectonic activity on Europa, Io, Ganymede and satellites of others of these planets
3. Roche's limit and presence of rings and major satellites
4. Magnetic Field strength - presence of metallic liquid hydrogen in planet's interior
5. Date and circumstances of discovery (Uranus, Neptune, and Pluto)

1. Definitions, characteristics, and classes of these objects (note similarities between Meteorites and Asteroid classes)
2. Age of dated samples and implications for origin of Solar System - orbits of asteroids, prediction of meteor showers
3. Characteristics of asteroids - esp. Vesta, Toutatis, Ida, etc?
4. Dirty Snowball model for comets - morphology and geology
5. Oort Cloud - what is it?
6. Kuiper belt - what is it?
7. Impact events on the Earth - What/Where is Chicxulub?

1. Why does life exist on the Earth?
2. Physical basis for life -
3. Miller Experiment - what does this show?
4. Past life on Mars, etc…
5. Why doesn't this book cover UFO's?
