Chapter 14 - Cosmic Samples and The Origins of the Solar System
- 14.1 Meteors
  - Learning Objectives
    - Explain what a meteor is and why it is visible in the night sky
    - Describe the origins of meteor showers
- 14.2 Meteorites: Stones from Heaven
  - Learning Objectives
    - Explain the origin of meteorites and the difference between a meteor and a meteorite
    - Describe how most meteorites have been found
    - Explain how primitive stone meteorites are significantly different from other types
    - Explain how the study of meteorites informs our understanding of the age of the Solar System
- 14.3 Formation of the Solar System
  - Learning Objectives
    - Describe the motion, chemical, and age constraints that must be met by any theory of solar system formation
    - Summarize the physical and chemical changes during the solar nebula stage of solar system formation
    - Explain the formation process of the terrestrial and giant planets
    - Describe the main events of the further evolution of the Solar System
- 14.4 Comparison With Other Planetary Systems
  - Learning Objectives
    - Describe how the observations of protoplanetary disks provides evidence for the existence of other planetary systems
    - Explain the two primary methods for detection of exoplanets
    - Compare the main characteristics of other planetary systems with the features of the Solar System
- 14.5 Planetary Evolution
  - Learning Objectives
    - Describe the geological activity during the evolution of the planets, particularly the terrestrial planets
    - Describe the factors that affect differences in elevation on the terrestrial planets
    - Explain how the differences in atmosphere on Venus, Earth, and Mars evolved from similar starting points in the early history of the Solar System
Chapter 21 - The Birth of Stars and the Discovery of Planets Outside the Solar System
- 21.1 Star Formation
  - Learning Objectives
    - Identify the sometimes-violent processes by which parts of a molecular cloud collapse to produce stars
    - Recognize some of the structures seen in images of molecular clouds like the one in Orion
    - Explain how the environment of a molecular cloud enables the formation of stars
    - Describe how advancing waves of star formation cause a molecular cloud to evolve
- 21.2 The H-R Diagram and the Study of Stellar Evolution
  - Learning Objectives
    - Determine the age of a protostar using an H-R diagram and the protostar's luminosity and temperature
    - Explain the interplay between gravity and pressure, and how the contracting protostar changes its position in the H-R diagram as a result
- 21.3 Evidence that Planets Form Around Other Stars
  - Learning Objectives
    - Trace the evolution of dust surrounding a protostar, leading to the development of rocky planets and gas giants
    - Estimate the timescale for growth of planets using observations of the disks surrounding young stars
    - Evaluate evidence for planets around forming stars based on the structures seen in images of the circumstellar dust disks
- 21.4 Planets Beyond the Solar System: Search and Discovery
  - Learning Objectives
    - Describe the orbital motion of planets in our solar system using Johannes Kepler's laws of planetary motion
    - Compare the indirect and direct observational techniques for exoplanet
