WGU D199 SUMMARY AND TEST
(INTRODUCTION TO PHYSICAL AND HUMAN
GEOGRAPHY) QUESTIONS AND
ANSWERS|GRADED A+
1. in the last 10,000 years: - ANSWER: humans began modifying the land
surface for growing food with advent of agricultural revolution
2. the agricultural revolution roughly - ANSWER: coincides with a warm
interglacial period that began about 11,700 years ago which is called the
HOLOCENE era (warm stable climate)
3. the last 270 years of the Holocene ushered into the - ANSWER: INDUSTRIAL
REVOLUTION when climate pollution began to increase dramatically
4. the industrial revolution was powered by - ANSWER: fossil fuels
5. what began after world war II?
- ANSWER: the great acceleration (1950-present)
-caused depletion in the ozone layer
-After 1950, the biodiversity of species started decreasing and the
extinction of species accelerated
6. The Great Acceleration marks the beginning of
- ANSWER: Homo sapiens' truly massive global imprint on the planet
-The climate has already warmed by 1°C since 1900.
-If humans continue with business-as-usual consumption of fossil
fuels, the warming between 1900 and 2100 could exceed 4°C.
7. the greenhouse effect.
- ANSWER: It is this trapping of heat energy that otherwise would have
escaped to space through the atmosphere
-allows solar radiation to enter
-the blanket effect
8. is the greenhouse effect real?
- ANSWER: -Satellites routinely measure the incoming solar energy and the
outgoing heat energy from the planet
-Independently, the heat energy emitted by the surface has been
estimated using observed surface temperatures on land and sea.
9. aerosols
- ANSWER: -Visible smoke and smog are made up of tiny particles
-carbon dioxide and other greenhouse gases cannot be seen by
the human eye #$%^&^%$#

ANSWERS|GRADED A+
-Most of these aerosols reflect sunlight and have a cooling effect
10. black carbon aerosols (a major component of soot)
- ANSWER: -absorb solar radiation entering the atmosphere and have a
warming effect.
-warms the climate by absorbing solar energy rather than infrared
energy from the planet
11. super pollutants
- ANSWER: -non-carbon dioxide greenhouse gases and black carbon particles
-per molecule, their warming effects are much larger than that of
carbon dioxide.
12. The Northern Hemisphere has warmed more than the Southern Hemisphere,
largely because - ANSWER: the ocean's influence
13. At current emission growth levels—that is, under a "business as usual" scenario
- ANSWER: -another trillion tons of carbon dioxide will be added to the
atmosphere by about 2030
-At that point, the rate of climate change will be three times faster
than the pace experienced until now.
-unchecked emissions will lead to warming that could exceed
4°C
14. Earth is now experiencing the Anthropocene Era
- ANSWER: -which means a time when environmental change is driven by
human activity
-One result of the Anthropocene Era is the increase in the
greenhouse effect, which might be better termed the
"atmospheric blanket."
15. evidence that human activity is the primary cause of global warming includes -
ANSWER: physical and satellite observations and the confirmation of the
predictions of scientific models.
16. How are satellites and weather balloons used with climate change model data? -
ANSWER: to confirm predictions
