AS101 Chapter Notes - Chapter 13: Seismic Wave, Planetary Science, Planetesimal
Document Summary
Chapter 13: comparative planetology of the terrestrial planets. Comparative planetology understanding planets by searching for and analyzing contrasts and similarities among them. Mantle the layer of dense rock and metal oxides that lies between the molten core and earth"s surface or a similar layer in another planet. P wave a type of seismic wave involving compression and decompression of the material through which is passes. S wave a type of seismic wave involving lateral motion of the material through which it passes. Secondary atmosphere a planet"s atmosphere that replaces the primary atmosphere, for example by outgassing, impact of volatile-bearing planetesimals, or biological activity. Greenhouse effect the process by which a carbon dioxide atmosphere traps heat and raises the temperature of a planetary surface. Global warming the gradual increase in the surface temperature of earth caused by human modifications to earth"s atmosphere. Subduction zone a deep trench where one plate slides under another.
