Global Systems + Solar Energy Flashcards
thin layer of land, water, and air
all life on earth exists here
biosphere
three main components of biosphere
- atmosphere
- lithosphere
- hydrosphere
gaseous portion of biosphere
mostly nitrogen and oxygen
contains other suspended particulate
atmosphere
nitrogen is for …
plants
oxygen is needed by … and supplied by …
animals
plants
1st layer of atmosphere
troposphere
ground-level layer
all weather phenomena occur here
15 °C
2nd layer of atmosphere
stratosphere
contins ozone gas
absorbs UV rays
-60 °C to 0 °C
3rd layer of atmosphere
mesosphere
meteors burn up here
0 °C to -100 °C
4th layer of atmosphere
thermosphere
almost a vacuum
-100 °C to 3000 °C
the land (crust and mantle)
lithosphere
outermost layer of geosphere
portion where humans exist
lithosphere
all water on Earth
hydrosphere
diff names for liquid and frozen water
hydrosphere vs cryosphere
do all components of the biosphere continuously interact
yes
where does the biosphere get energy from
the Sun through radiation
open system
matter and heat/energy escape
through boundary
closed system
only heat allowed to escape
isolated system
no heat or matter allowed to cross boundary
what type of system is earth + why
CLOSED
solar radiation enters, radiant energy leaves
meteorites n spaceships r the exceptions
solar energy that reachers Earth in form of light, Uv radiation + some infrared radiation
electromagnetic radiation
waves from longest wavelength to shortest length
RMI V UXG
shorter wavelengths vs longer wavelengths absorption place in geosphere
shorter - lower atmosphere by water + CO^@
longer - upper atmosphere
energy in shorter vs longer wavelengths
shorter - higher
longer - lower
how energy distributed on Earth
absorbed in atmosphere - 23%
reflected - 29%
absorbed at surface - 48%
diff between incoming radiation and all outgoing radiation
net radiation budget
net Rad. Budget. =
Incoming Rad. - Outgoing Rad.
ability of surface to reflect energy
albedo
dark vs light surfaces in terms of albedo
dark - low albedo
light - high albedo
most greenhouse gases in a atmosphere r
CO^2 methane gas (CH^4)
