strong>Heat Transfer– Conduction, Convection and Radiation measured as thermal energy (temperature) which is the motion of moelsules of a substance
Radiation – Sunlight or suns rays
Conduction – the direct transfer of heat from one substance to another (sunlight hitting the surface)
Convection – Heat transfer by fluid (gas,liguid) where cooler air/water sinks due to its heavier density replacing warmer air/water
Solar radiation – The sun prodoces the most energy 90% and plants use it to produce sugar called photosynthesis, then the Earth (geothermal,wind, etc), and then society produces very little (people)
Photosynthesis – CO2 + H2O –> C6H12O6 (sugar) + O2
Coriolis Effect – because of earths tilt and direction of rototaion ( global winds in the northern hemisphere turn to right, and in the southern hemisphere turn to the left)
Unequal heating – more direct sunlight hits the equator than the poles
Latitude – distance from the equator measured in degrees (horizontal lines) air sinks at 30 degrees creating hadley cells and most deserts and rainforests are distributed in bands located near this area where air rises and sinks
Jet stream – air current that travels around earth at 200-400 km/hr
Rainshadow effect – Winds get moist or wet (cold) when they ascend up a hill or mountain(windward side), and Dry and warm on the leeward side creating deserts
Air masses – huge bodies of air that move along earth
Tropical – start equator and move towards poles (warm)
Polar – start at poles and move toward the equator (cold)
Maritime – start on water and move towards land (wet)
Continental – move over continents and are Dry
Maritime tropical – wet humid air masses
Maritime Polar – Cool humid air masses
Continental tropical – Dry warm air masses
Continental Polar – Cold dry air masses
Factors affecting climate – Latitude – tropical zone is at 0 degrees lat. (equator) to 23.5 degrees north and south lat.and receives the most direct solar radiation, Temperate sone is located at 23.5 degrees n/s lat to 66.5 degrees N/S latitude which brings warm hot summers and cool winters
Altitude : higher altitudes have cooler climates
Distance to large bodies of water: mild marine climates and more humid summers
Long term changes in climate: fossil evidence suggests 4 major ice ages in earths history which include variations in earths position relative to the sun, suns energy output, and the movement of continents.
El nino’s – wind patterns in the pacific that bring warm air into ocean and bring precipitation to california and ocuur every 7 years and Mexico + south america,
CFC’s (chloroflourocarbons) air conditioners, refridgerants, and aerosol cans deplete the ozone layer and increase solar radiation hitting earth




Monday April 9
No QFD or ?FD this week

Objective: To understand the California Earth Science standards at a level to pass proficiently or better
4. a. Students know the relative amount of incoming solar energy compared with Earth’s internal energy and the energy used by society.
b. Students know the fate of incoming solar radiation in terms of reflection, absorption, and photosynthesis.
c. Students know the different atmospheric gases that absorb the Earth’s thermal radiation and the mechanism and significance of the greenhouse effect.
d.* Students know the differing greenhouse conditions on Earth, Mars, and Venus; the origins of those conditions; and the climatic consequences of each.
1) notes
Weather is the condition of Earths atmosphere at a particular time and place (short term)
Climate is the condition of the atmosphere over time (long term)
Atmosphere – 78% nitrogen, 19-21% oxygen, Argon 0.93% , CO2 0.036% and water vapor (clouds/precipitation)
Ozone – located in the stratosphere and is O3 and helps keep Earth warm by trapping heat and carbon dioxide in the lower atmosphere
Photochemical smog – caused by the action of sunlight and chemicals in the air creates a brown haze when pollutant react with one another in the air
Temperature Inversions – when a layer of warm air is trapped between 2 layers of cold air producing smog
Air pressure – result of columns of air pushing down on an area. High pressure (happy weather) little clouds, Low Pressure (lowsy weather) cloudy, precipitation
Air pressure decreases as altitude increases (lower pressure in Big Bear)
Barometer – measures air pressure (aneroid and mercury) measured in millibars
Layers of the atmosphere (from ground upward) – Troposphere, Stratosphere, Mesosphere, Thermosphere
Theresa should make tacos
Troposphere – where we live, weather and the most changing conditions exist temperature decreases with altitude
Stratosphere – Layers of Ozone – temperature increases with altitude
Mesosphere – Meteroids burn up as they enter atmosphere here- temperature decreases with altitude
Thermosphere – Aurora Borealis (Northern Lights) satelites – temperature increases with altitude
Electromagnetic waves – form of energy that can travel through space and classified according to wavelength
Radiation – direct transfer of energy and sunlight enters atmosphere as ultraviolet radiation and bounces off the surface as infrared radiation
Approximately 55% of Ultraviolet radiation (most) hits the Earths surface, 30% bounces back into space, and the remainder is scattered by clouds, water vapor and particles in the atmosphere
Greenhouse Effect – The trapping of heat by radiation near earths surface and is affected by increases in Carbon Dioxide (burning fossil fuels, gas, and manufacturing increase the greenhouse effect) Greatest on Venus (lots of CO2) HOT, then Earth (moderate CO2) WARM, and very little on Mars COLD
