What is the range of detail that can be displayed in Google Earth?
answer
Google Earth can display in scales ranging from the entire Earth down to street level.
Google Earth uses satellite images wrapped around a 3D model of the Earth, aerial photography, and street-level photography.
question
How is Google able to map roads and display street-level imagery in Google Earth?
answer
by driving cars equipped with special cameras along the streets
Cars are just one of the ways that the imagery is collected. Google also uses tricycles, walking, and trekker backpacks.
question
How was Google Earth used as a tool by a tribe living in the Amazon rainforest?
answer
Tribe members used Google Earth to help fight against encroachment from logging activities.
Because they were able to identify their local area on satellite images, they were able to delineate their tribal areas and then use this information in their fight against the encroachment.
question
How was Google Earth used to inform public opinion about atrocities committed in Darfur, Sudan?
answer
Imagery in Google Earth showed villages that had been burned by Sudanese troops.
The government response to the uprising in Darfur included ethnic cleansing and genocide with casualties estimated to be in the hundreds of thousands.
question
What was the impact of the Martellus map on the voyages of Christopher Columbus?
answer
It convinced Columbus that China was much closer that it really was.
Using Ptolomy's calculations, Martellus underestimated the circumference of the Earth by nearly 7,000 miles.
question
How did the first maps following the voyages of Columbus portray the New World?
answer
The Americas were shown without a complete west coast.
Cartographers portrayed the New World in such a way that implied it was connected to Asia.
question
Why is the Waldseemüller map significant historically?
answer
It is the first map to incorporate the name "America."
The name America is derived from a Latin version of the name of Amerigo Vespucci, an Italian explorer who first showed that the West Indies were not part of Asia.
question
Weather V. Climate
answer
Weather
Climate:
question
The effect of aerosols on weather and climate
answer
The ash and smoke could lead to an increase in clouds and fog.
Global temperatures could decrease.
The composition of the atmosphere affects climate and weather. In our eruption scenario, global temperatures could decrease and the ash and smoke could lead to an increase in clouds and fog.
question
Which of the following locations experiences the greatest seasonal variations of carbon dioxide concentrations?
answer
North America
As the video shows, seasonal variations in carbon dioxide concentrations are greater in the Northern Hemisphere than in the Southern Hemisphere. This is mainly because the Southern Hemisphere contains substantially less land area than the Northern Hemisphere, and thus fewer terrestrial plants exist in the Southern Hemisphere to go through these seasonal cycles of photosynthesis and respiration.
question
Which of the following locations, over the course of the video, has the highest concentration of carbon dioxide?
answer
Greenland
Throughout the video, Greenland is one of the countries with the highest levels of carbon dioxide concentrations overall.
question
Which of the following locations, over the course of the video, has the lowest concentration of carbon dioxide?
answer
The southern part of South America
Over the course of the video, the southern part of South America has the lowest carbon dioxide concentrations, relative to the other choices.
question
Meteorology
answer
is the study of the atmosphere and its related weather systems.
question
A primary difference between the concepts of weather and climate is the:
answer
time period involved.
question
The majority of the water outside of the oceans is in the form of:
answer
glacial ice.
question
This variable atmospheric component can exist in all three states of matter (solid, liquid, and gas) at the temperatures and pressures that normally exist on Earth.
answer
Water
question
What best explains the "bumps" seen in the seen in the CO2 concentrations on the graph above?
answer
changes in plant growth that result in less CO2 being absorbed during the dormant season
question
This atmospheric component absorbs damaging ultraviolet radiation from the Sun.
answer
Ozone
question
Atmospheric pressure is caused by:
answer
the weight of the air above.
question
The four thermal layers of the atmosphere in order beginning from the surface are:
answer
troposphere, stratosphere, mesosphere, thermosphere
question
The "weather sphere" is in the:
answer
troposphere.
question
Which parameter best defines the primary difference between weather and climate?
answer
Time
Weather typically refers to the short term, such as rain or sun this afternoon. Climate is the generalized influence of weather over a long span of time.
question
Which of the following is not among the elements of weather?
answer
time of sunrise and sunset
Correct! Though a prediction of this phenomenon often accompanies weather reports, it is not considered one of the basic elements of weather. However, would you expect that the time of sunset and sunrise could affect the day's weather?
question
In considering a move to a place that is unfamiliar to you, what information about weather and climate would be most useful?
answer
long-term climate data
Correct! Weather for the past few days might give you an idea of a trend, but long-term climate data would give you a better idea of what to expect, as well as the extreme cases.
question
Which weather-related phenomenon resulted in the most fatalities during the 30-year interval between 1977 and 2006?
answer
floods
Correct! According to statistics, more fatalities were attributed to floods than any other weather-related cause between 1977 and 2006.
question
In terms of dollars, which type of weather event caused the most damage in the United States between 2004 and 2006?
answer
hurricanes
During the time between 2004 and 2006, eight hurricanes resulted in over $6.5 billion dollars each in damages.
question
Which of the following phenomena is not an example of how humans have contributed to disruption of the atmosphere?
answer
wind turbines
The generation of electricity by wind turbines makes use of air movements within the atmosphere, but it is not thought to cause major disruption nor harmful side effects, even with increased application.
question
Which of the following is both a daily need and directly tied to weather patterns?
answer
food and water
Correct! Significant changes in weather patterns can cause drought, floods, and changes in precipitation patterns. These changes can dramatically influence agriculture and water quality.
question
Which specific gas is most abundant in Earth's atmosphere?
answer
nitrogen
Nitrogen represents 78.08 percent of the specific gases that make up the atmosphere.
question
Which gas in the atmosphere is vital to virtually all life that exists on Earth?
answer
oxygen
Though not the most abundant gas in Earth's atmosphere, oxygen is vital to the survival of most organisms.
question
Which gas in Earth's atmosphere has a significant role in the heating of the atmosphere?
answer
carbon dioxide
Carbon dioxide gas in the atmosphere is able to absorb heat generated by Earth and by humans, and thus influences heating of the atmosphere.
