1
New cards
Passive Solar
absorbing or blocking heat from the sun, without use of mechanical/electrical equip
2
New cards
Active Solar
use of mechanical/electrical equip to capture sun’s heat (solar water heaters or CST-concentrated solar thermal), or convert light rags directly into electricity (PV cells).
3
New cards
Photovoltaic Cells (PV)
Aka “solar panels”; contain semiconductor (usually silicon) that emits low voltage electrical current when exposed to sun.
4
New cards
Where do winds move?
Winds move north and south on the Earth's spherical surface
5
New cards
Polar air masses are:
Originating between the Arctic Circle and the North Pole or between the Antarctic Circle and the South Pole. They are characteristically cold.
6
New cards
Tropical air masses are:
Originating between the Tropic of Cancer and the Tropic of Capricorn. They are warm air masses.
7
New cards
Continental polar (cP)
cold, dry air mass
8
New cards
Continental tropical (cT)
a warm, dry air mass
9
New cards
Maritime polar (mP)
a cold, moist air mass
10
New cards
Maritime tropical (mT)
a warm, moist air mass
11
New cards
Positive Feedback Mechanism
amplifies
12
New cards
Negative Feedback Mechanism
counteracts
13
New cards
Coriolis Effect
deflection of objects traveling through due to spin of the Earth
14
New cards
Anything in the Northern Hemisphere
deflects right
15
New cards
Anything in the Southern Hemisphere
deflects left
16
New cards
Hurricanes
spin counterclockwise. Formed in Northern Hemisphere
17
New cards
Cyclones/Typhoons
spin clockwise. Formed in Southern Hemisphere
18
New cards
Global Wind Patterns
air moves between the warm equator and the cold poles
19
New cards
Open System
heat transfer, mass transfer
20
New cards
Closed System
heat transfer, NO mass transfer
21
New cards
Higher latitudes recieve
less insulation (cooler, less precipitation)
22
New cards
Rain shadow
Eastern trade winds blow moist air from the Atlantic across South America
23
New cards
how many watts are in a kilowatt
1000W = 1kW
24
New cards
Nuclear is not
endlessly renewable. Relies on uranium.
