MODULE 3 Flashcards
Carbon in the atmosphere is largely found in the form of the following, except:
CO
CO2
CH4
CFC
CO
t or f: In an urban setting when there is little to no wind, variations in temperature are more felt in the night than day time.
T
The following are sources of trace gases that accelerate the greenhouse effect, except:
Fossil fuel, croplands, aerosols, cars, refrigerators
croplands
Ecological footprint measurement takes into account the following, except:
Forested Land Area, Ocean carbon absorption, carbon emissions of human activities, none of the choices
none of the choices
The average global temperature has increased by 1.4 degrees since ____
1880
the buildings blocks fo all organic compounds
carbon
The four major earth systems
biosphere, atmosphere, hydrosphere, and geosphere
T OR F; Before the Industrial
Era, circa 175 biospheric carbon dioxide (CO2) concentration was 280 ± 10 ppm for several
thousand years.
false: should be atmospheric
this is produced by burning fossil fuels
carbon dioxide
byproduct of agriculture
methane
from car exhaust
nitrogen oxides
aerosol and refrigerators
CFC
the warmest year in measured history for the past 12 years
1998
the greenhouse gases that reached their highest levels that melt the arctic sea
carbon dioxide
and methane
In the last century, the earth’s temperature has raised about____
0.036 – 0.042O Celsius
t or f: Researchers report that temperature will increase 0.3O Celsius by the end
of the decade.
false; should be century
In
the _____, carbon is found primarily in the form of bicarbonate ion (HCO3), which forms from the
dissolution of carbon dioxide in water. (carbonic acids to bicarbonate ion)
hydrosphere
In the
______, carbon is found predominantly in molecules of carbon dioxide (CO2) and methane (CH4).
atmosphere
In the ______, large volumes of sedimentary and metamorphic rock are
composed of carbonate minerals making up carbonate rock (limestone, dolostone, and marble),
geosphere
The______ introduced the method ecological footprint to measure biocapacity
or the productive area that can regenerate all the goods and services people demand from nature. In a
simplest term, this is use to quantify the human impact on the environment. T
Global Footprint Network (GFN)
carbon
footprint can also be expressed as the amount in tons of _______
co2 emissions
An urban heat island (UHI) is a metropolitan area that experience significantly ____temperature than
surrounding rural areas because of man-made activities.
warmer
_______ are considered as sentinels of climate change (Adrian et al., 2009) and are therefore excellent
study ecosystems in order to better appreciate the impacts of climate change. The Intergovernmental
Panel on Climate Change and Millennium Ecosystem Assessment both recognize the threats lake
ecosystems face today.
lakes
The carbon component of the
ecological footprint (carbon footprint) measures the _____that is required to absorb all the
______ from human activity in excess of what the ______ already absorb.
area of forestland, carbon emission, oceans
