Exam 2 Review This “review sheet” has a list of questions that you can ask yourself to get a feel for your own comfort level on the different topics that we’ve covered in class. Exam 1 Carry-over: Are you able to write numbers in scientific notation and read/interpret numbers presented in scientific notation? Can you use scientific notation to make calculations? Do you know how to use your calculator properly? Matter/Light Properties Can you describe the structure of an atom? Do you know what makes one element different from another? What is an isotope? What is a molecule? Do you understand how the concept of temperature is related to the motion of atoms/molecules? Can you define the wave properties of light (wavelength, frequency, speed of light)? Do you understand how light can be described as a particle (photon)? Do you know the basic principles of the reflection and refraction of light? Do you know how to compare the different parts of the EM spectrum with regards to wavelength, frequency, and energy? Do you know how light and matter interacts to form an absorption spectrum? Planet Properties: Are you comfortable with the following properties of planets? Can you use a table of planetary properties to compare the characteristics of the planets of the Solar System? Semi-Major Axis Eccentricity Orbital Inclination Rotational Inclination Average Density Albedo Orbital Period Rotation Period Equatorial Radius Oblateness Surface Gravity Escape Velocity What are the general properties of the Terrestrial Planets and the Jovian Planets? Astronomy History: Do you understand the differences between the geocentric model of the universe and the heliocentric model? What were the observations that supported each of the models? Can you identify the contributions to astronomy that were made by the following individuals? Claudius Ptolemaeus (Ptolemy) Aristarchus Nicolas Copernicus Johannes Kepler Galileo Galilei Isaac Newton How well do you understand Kepler’s Laws of Planetary Motion? How well do you understand Newton’s Laws of Motion and the Law of Gravity? Earth Can you describe the basic structure of the Earth’s geology? Do you understand how scientists know the properties of the Earth’s interior? Do you know what types of geologic formations are located above the three different plate boundaries? Can you describe the basic structure of the Earth’s atmosphere? Do you understand how the ozone layer prevents UV photons from getting to the surface of the Earth? Can you describe how the Greenhouse Effect keeps the surface of the Earth at a temperature of about 15 degrees Celsius? Do you understand how the magnetic field of the Earth is generated and how that magnetic field protects Earth from the Solar Wind and creates aurora? Moon: Can you describe the general properties of the Moon in terms of its geologic structure, surface features, and atmosphere? Do you know how craters are formed? Do you know how the relative ages of the lunar highlands and mare can be determined? Do you know what causes the phases of the Moon? Do you understand how the tides of the Earth are affected by the Moon? Do you know the different types of eclipses that occur and what conditions that need to be met in order for an eclipse to occur?
