AREA’S OF REVIEW FOR THE EARTH SCIENCE FINAL Geologic Time (chapter 21) Describe the geologic time scale (what is it & how is it constructed) Identify the Geo. Time scale divisions & their order (eon, era, period, epoch) Principle of uniformitarianism Geologic principles (original horizontality, superposition, cross-cutting relationships) Relative age of rock determined by (Inclusions, unconformity, cross-cutting relationships) Absolute dating methods (dendrochronology (tree rings), radioactive decay, & radiocarbon) Know what evolution is by definition Methods by which fossils can be preserved (original preservation, permineralization, index fossils, mold, cast) General understanding of the events of geologic history (era dinosaurs lived/died, when abundant life first appeared, largest extinction, era mammals became dominant, etc.) The Sun-Earth-Moon System (chapter 28) Electromagnetic radiation (types of light & wavelengths) Tools of astronomy Telescope types & Interferometry o Ground based vs. space based astronomy o Telescopes using light other than the visible part of spectrum Lunar properties (highlands, craters, rays, rilles, albedo etc.)-why craters on the moon & not Earth? Composition of the moon Impact Theory of Moon’s formation Phases of the Moon (know the waxing and waning phases) Eclipses (know how eclipses and phases relate) – how to the umbra and penumbra relate to eclipses Relationships between the Sun, Moon, and Earth (solstices, equinoxes, daily motions, annual motions, apogee, & perigee) Reasons for the seasons Our Solar System (chapter 29) Heliocentric model of our solar system (perihelion, aphelion & astronomical units) Relate gravity to the motions of celestial bodies (Kepler’s first, second and third law) Properties of terrestrial planets & gas giant planets Comets & Asteroids (meteoroid, meteor, meteorite) – what are they and what’s the difference Characteristics of dwarf planets Stars/Sun (chapter 30) Parts of the Sun (photosphere, chromosphere, corona, solar winds, sunspots, solar flares, prominence) Solar interior (fusion, fission) Solar composition (hydrogen/helium) Stellar spectra (continuous, absorption, emission) & star composition Types of stars (super-giants, white dwarfs, main sequence) Properties of stars (magnitude, apparent magnitude, absolute magnitude, luminosity) What properties make a star bright? Classification of stars (spectral types O,B,A,F,GK,M) Doppler Effect & wavelength shifts- (blue-shift vs. red-shift) H-R diagrams Star formation (nebula, protostar, white dwarfs, supernovae, neutron star, black hole) Galaxies and the Universe (chapter 31) Characteristics of the Milky Way Galaxy (halo, nuclear bulge, disk, globular clusters, spiral arms, population I vs. population II, & where’s most of it’s mass found) Usefulness of variable stars, RR Lyrae variables, and Cepheid variables & quasars Classification of galaxies (elliptical, barred spirals, spiral, irregular)) Expansion theories of the Universe (Hubble’s Law/Hubble constant – farther a galaxy is the faster it moves) Cosmology-study of the Universe Big Bang theory (cosmic back ground radiation, expansion rate, unknown force is accelerating the expansion of the universe) What is the Doppler Effect? (know blue-shifts & red-shifts) Atmosphere (chapter 11) Atmospheric composition (key gases, ozone) Structure of the atmosphere (troposphere, stratosphere, mesosphere, thermosphere, exosphere) Energy transfer (radiation, conduction, convection) Properties of the atmosphere (temperature, dew point, condensation, wind) Vertical temperature changes (lifted condensation level, adiabatic lapse rate) What are temperature inversions? Relative humidity vs. humidity (how are dew point & saturation related) Cloud formation) o Processes that lift air (condensation nuclei, orographic lifting, frontal wedging, & convection) o Lifted condensation level o Condensation nuclei Atmospheric stability vs. instability Latent heat during phase changes of water (evaporation absorbs heat, condensation releases heat) Characteristics of cloud groups (cirrus, cumulus, stratus, nimbus) Precipitation (coalescence) Water cycle (evaporation, condensation, runoff, groundwater, precipitation) Energy budget- balance of temperatures), absorption vs. reflection Condensation nuclei and their relation to cloud formation Meteorology (chapter 12) Weather vs Climate Types of air masses/where they form (A, mP, mT, cP, cT) Air mass modification & stability (ch 11) Coriolis effect- deflects air due to Earths rotation (N. Hemisphere vs. S. Hemisphere) Wind systems/ and locations- (polar easterlies, prevailing westerlies, trade winds, jet stream) Types of fronts/symbols for fronts/characteristics for fronts (cold, warm, stationary, occluded) Compare and contrast high pressure systems to low pressure systems Weather instruments (thermometer, barometer, anemometer, hygrometer, ceilometers, radiosonde) Weather radar vs weather satellites (infrared imagery) The Nature of Storms (chapter 13) Formation of thunderstorms Dangers of Severe thunderstorms (lightning, hail, high winds, and floods) General steps in the formation of tornadoes Tornado safety Formation of hurricanes/dangers of hurricanes Classification of hurricanes-Saffir-Simpson hurricane scale Origin of tropical cyclones Life cycle of a tropical cyclone Cold waves vs heat waves Cause of lightning Description of a draught
