It occurs to about 500 km
above the Earth’s surface
What is ATMOSPHERE?
It includes all of the Earth’s
water: fresh water, salt
water, ice, and water vapour
What is
the HYDROSPHERE?
Livestock (…mainly
cattle….) and bacteria
release this heat-trapping
gas.
What is METHANE (CH4)?
As air rises over these, it
cools and water vapour
condenses and falls to Earth
as precipitation on its
windward side
What is MOUNTAINS?
In the troposphere, this
gas is a corrosive, toxic
gas which is a component
of smog.
What is OZONE?
O
22.1
O
24.5
It varies from
to
over a 41,000 year period
What is
the TILT of the Earth?
Unlike other substances, this
substance expands when it
freezes.
What is WATER?
This is caused by the
earth spinning but not in a
straight line (…like a
top…) due to the masses
of oceans and mountains
What is
the WOBBLE of the Earth on
its axis?
Amount of radiation
emitted by the Sun varies
on a periodic cycle
What is
SOLAR VARIATION?
These release huge amounts
of dust into the atmosphere
that reflects more radiation
back into space and, in the
short term, cool the Earth
What are
VOLCANIC ERUPTIONS?
While atmospheric CO2
concentrations have
increased above normal
cyclic levels, this other
measure is not above normal
levels
What is
TEMPERATURE?
A term for “resulting from
human influence”
What is
ANTHROPOGENIC?
A natural or artificial
reservoir that accumulates
and stores some carbon for
an indefinite period.
What is
a CARBON SINK?
It is part of the large-scale
ocean circulation that is
driven by differences in
water density, water
temperature and salt
concentrations
What is
THERMOHALINE
CIRCULATION?
A response to the output
signal in the same direction
as the signal and, in a cycle,
an increase in the original
output signal.
What is
POSITIVE FEEDBACK LOOP?
Invest in ideas and wait for
tomorrow
What is
TECHNOLOGICAL HOPE?
Ignore the problem and
assume the natural processes
will return the change to more
“normal” conditions
What is DO NOTHING?
A measure of human
demand on the Earth's
ecosystems
What is
ECOLOGICAL FOOTPRINT?
Do not correct the problem;
rather, spend resources and
energy adjusting
What is ADAPTATION?
It is how Ecological
Footprint is measured
or represented
What is
the NUMBER of Earths it would
take to support humanity if
everybody lived a given
lifestyle?
