AST101 Review Session Two
November 6th, 2012
- format is more or less identical to the last midterm--similar number of question and
breakdown--some drawing diagrams, some writing things out
- bring a pen, pencil, eraser, and T-Card
- Kepler's laws, light-year, scale of the solar system, AU, etc.
- about the solar system - chapter 5, 7, 8, 9, 10, 11
- wavelength, frequency, energy, and colour--how are these things related?
- which kinds of light make it through our atmosphere?
- three types of spectra - know what they are, and what type of object makes them
- what atomic processes are going on -- electrons moving around that produce or absorb
light and how this is related
- how do you use a spectrum of an object to learn about it
- temperature, chemical composition, moving towards or away from you
- general patterns of motion in solar system
- general patterns and chemical composition of planets
-general properties of planets - size, temp, etc.
- more detailed properties of each planet
- formation of the solar system
- conditions in the early solar system
- giant impacts - the moon, uranus, etc.
- age of the solar system
- carbon dating - radio-nuclei dating
- formation of moon
- terrestrial planet surfaces and processes that shape them
- terrestrial planet interiors
- jovian planets
- cratering, plate tectonics, erosion
- heating and cooling interiors - what determines rate of cooling and how this relates to
- comparative planetology
- carbon cycle - climate and temp. regulated of terrestrial planets
- interior structure of jovian - colours, structure, etc.
- moons and rings of jovian planets
- magnetic ﬁelds need a molten core, and rotation
- anytime you have a charged material that is moving, it will generate a magnetic ﬁeld - in the earth, that charged material is the molten core
- the motion generates a magnetic ﬁeld
- solar wind: charged particles emitted by the sun and streaming out into space
- when these particles interact with the magnetic ﬁeld, they slide along
