Title: Science 9 Review for the Climate Change


1
Science 9 Review for the Climate Change
2
  • 1. The surface features of the earth are called
    ______________.

topography
3
  • The process by which carbon moves from sphere to
    sphere.

Carbon cycle
4
  • Areas that absorb and store carbon (when carbon
    is not moving through the cycle)

Carbon sink
5
  • Carbon containing materials that formed over
    millions of years through the decay, burial, and
    compaction from rotting vegetation on land and at
    the sea floor.

Fossil fuels
6
  • One of the GHGs that is commonly found in
    fertilizer

Nitrous oxide
7
  • Heavy colorless gas that is formed especially in
    animal respiration (exhaling), burning of trees,
    or decay of vegetation.

Carbon dioxide
8
  • The long term removal of trees from an area
    because of changes in land use.

deforestation
9
  • The study of ancient climates through ice cores,
    tree rings and pollen.

paleoclimatology
10
  • The average weather for a particular region over
    time.

climate
11
  • A system that does not allow for the exchange of
    matter between boundaries.

Closed system
12
  • Layer of permanently frozen ground

permafrost
13
  • A gas that is produced by organic matter
    decomposing in an environment w/o oxygen. ( cows
    give off this gas)

methane
14
  • The effect produced by GHGs allowing solar
    energy to pass through the earths atmosphere,
    but preventing it from escaping.

Green House Effect
15
  • A FRACTION OF THE SOLAR ENERGY REFLECTED FROM THE
    EARTH SURFACE BACK INTO SPACE IS
    CALLED______________.

ALBEDO
16
  • A chemical compound found in aerosol cans that
    causes a depletion of the ozone layer.

CFCs
17
  • Trees and plants commonly absorb _____________
    from the atmosphere in a process called
    ________________.

Carbon dioxide, photosynthesis
18
  • The _________ is a layer of gases that surround
    the earth like a blanket.

atmosphere
19
  • List the three major carbon sinks

Ocean, soil, forest and vegetation
20
  • _________ is the GHG that is most damaging to
    the ozone layer

CFC
21
  • WHAT WAS DEVELOPED TO REPLACE CFCs?

HFCS
22
  • Gases in the atmosphere that prevent incoming
    solar radiation from escaping
  • back into outer space.

GHGs
23
  • How do volcanos impact the atmosphere and
    climate?

Dust and gas thrown into air. This dust blocks
the suns rays.
24
  • Do the number of clouds effect the atmospheric
    Albedo? How?

Yes. More clouds more reflection which means
less of the suns rays reach earth
25
  • How does an increase in water vapor effect the
    atmospheric albedo?

Increased water vapor increased clouds more
reflection
26
  • How does an melting ice and snow effect the
    surface albedo?

Melting snow means less reflection of the suns
rays. (Earth absorbs sun rays.)
27
  • What are 3 external forces that effect climate?

Shape of earths orbit, tilt of axis, and wobble
28
  • How do the continental movements cause climate
    change?

Suns rays hit continent at a different angle,
therefore, changing climate by more or less suns
rays hitting. Changes flow of ocean currents.
29
  • What are the names of the earths four main
    subsystems? (spheres)

Biosphere, hydrosphere, lithosphere, atmosphere
30
  • Methane is present in much lower levels than
    carbon dioxide. Why is it such a concern?

It traps 20 more times heat than carbon
31
  • Fertilizers and manure produce what type of GHG?

Nitrous Oxide
32
  • Earths rotation makes winds seem to curve. This
    is known as the _____________.

Coriolis Effect
33
  • What is the purpose of the GHGs?

Keep the temperature on earth balanced.
34
  • Are GHGs bad?

No. Too many are accumulating in our atmosphere.
35
  • Is carbon dioxide increasing, decreasing or
    stable on earth?

Stable. It is being moved from one sphere to
another. Too much is in atmosphere.
