Study Notes
Earth's Shape and Movement
- Earth is an oblique spheroid
- Circle of illumination is the great circle separating day and night
- Earth's axial tilt is 23 ½ degrees
- Winter Solstice occurs on December 21 or 22 in the Northern Hemisphere, with the subsolar point at the Tropic of Capricorn
- Tropic of Cancer is the subsolar point at 23.5 N latitude during the summer solstice, with a 90-degree angle of incidence
Atmospheric Pressure and Winds
- Chinook wind, meaning "snow eater", occasionally warms Calgary
- Standard air pressure unit is the millibar
- Coriolis force deflects movement on rotating bodies
- Windward side of a mountain is exposed to the wind
- Sea breeze blows from water to land during the day
Earth, Air & Wind
- Polar Highs result from large high-pressure systems over the poles
- Equatorial Low is caused by a large low-pressure system at the equator
- Northeast Trades return to the equator in the Northern Hemisphere, deflected northeast
- ITCZ stands for Inter-tropical Convergence Zone
- Westerlies are mid-latitude winds between 30N and 60N
Ocean Currents
- Upwelling involves the rising of cold water from ocean depths
- Ocean current meander is a river-like curve
- Gyre is a continuously moving loop of water in an ocean basin
- Thermohaline Circulation is the deep-sea ocean movement system
- Southern Oscillation occurs when El Niño happens with westward surface windflow
Severe Cyclones
- Cyclogenesis is the formation of mid-latitude cyclones
- Low-pressure trough is an elongated, depressed area of air pressure in the upper atmosphere, often associated with clouds and rain
- Downdraft is a rapidly moving current of cool air in a thunderstorm
- Supercell thunderstorms have opposing winds, strong winds, lightning, thunder, and possible hail and tornadoes
- Tropical storm has sustained winds between 63 km/h and 118 km/h
Weather Wonders
- Freezing is the process of water turning to ice
- Dew forms when water vapor increases past saturation levels on mountains
- Precipitation is any liquid water or ice falling to Earth
- Psychrometer measures relative humidity
- Latent heat is the heat involved in melting
Rain, Rain Go Away
- Hail consists of ice crystals in continuous circulation above and below freezing level
- Convection is spontaneous vertical air movement in the atmosphere
- Thunderstorm mature stage has updrafts continuing, creating cumulonimbus clouds
- Orographic precipitation results from lifting over a topographical feature
- All precipitation results from air lifting
Climatic Alphabetizing
- Tropical climates are represented by letter A
- Polar climates are represented by letter E
- Dry climates are represented by letter B
- Koppen climate classification system provides a balanced approach
- Koppen's system is based on plant life
Climate Change
- Stretch involves changes in Earth's orbit influencing climate
- Roll involves changes in Earth's declination affecting climate
- Wobble represents changes in Earth's axial shifting impacting climate
- Anthropogenic forces are human-caused climate change factors
- Expansion due to heat is the main reason for rising sea levels
Sweet Sustainability
- Noahic Covenant includes all living creatures on Earth
- Carrying Capacity is the maximum ecosystem population support
- Sumeria, a civilization between 4000 and 2300 BCE in southern Iraq, ruined its arable land through irrigation
- San Joaquin Valley in California is becoming increasingly saline due to irrigation
- Revelation 11:18 foretells God's destruction of those who damage the Earth
Final Jeopardy
- Death awaits everyone, regardless of climatic conditions.
