Which of the following is the largest "carbon sink" on Earth?
Deforestation results in everything except:
Lower CO2 absorption
Warmer relative surface temperature
Decreased erosion
Increased CO2 release
Permafrost traps CO2 because
It prevents decomposition
It prevents deforestation
It allows decomposition
It absorbs CO2
Records of CO2 have been determined by (select 2)
Collecting direct data in Muana Loa, Hawaii
We have no real data
From scientists dating back to the Medieval Ages
From ice cores
Leaf Out data has shown
Dates have gotten earlier
Dates have gotten latter
Dates have no pattern, changing completely at random
Dates have stayed the same
Ice Cover data from Lake Mendota, WI, has shown there is
Decreasing ice cover
Increasing ice cover
No change in ice cover
Which of the following are types of Global Change?
Climate Change
Land Use
Invasive Species
Atmospheric CO2 Levels
All of these are examples of Global Change
To have the most likely and accurate conclusions, scientists try to use
Only data as old as the scientist involved
Data that will fit their agenda
Whatever data has happened in the last 10 years
The most complete and long term data
Greenhouse gases affect the world by
Reflecting most of the solar energy causing warmer temperatures
Trapping more solar energy causing warmer temperatures
Reflecting most of the solar energy causing cooler temperatures
Trapping more solar energy causing cooler temperatures
On a sunny summer day, which spot will likely have a higher temperature?
On a sunny summer day, which spot will likely have a lower temperature?
Warmer oceans result in all the following except
Stronger Storms
Less CO2 absorption
Greater CO2 absorption
Increased ice cap melting
Invasive species (select two answers)
come from a different location
come from the invaded location
cause no damage/changes
cause damage/changes
This image shows a trend of
Ice cover days getting fewer on average
Ice cover days always decreasing year to year
Ice cover days getting greater on average
Ice cover days always increasing year to year
Global warming means that each year will always be warmer than the previous year
Countries have differences in rank of total CO2 and per capita CO2 due to
Different populations
Different wealthiness
Different industrialization
All of the above are reasons for differences in rankings
