The Global Climate System Quiz Questions

1.

Select the following situations that point toward evidence of global climate change.

A.

Keeling Curve - data collected by NOAA in Mauna Loa Observatory shows increase of CO2 over the past 60 years due to an increase in industry (14%), fossil fuel combustion (32%), and electricity use (38%).
B.

Wisconsin Lakes - data collected in Lake Monona show that the span of the lake staying frozen has decreased over the past 50 years by about 29-35 days each year.
C.

Montana Glaciers - data collected via repeat photography conducted by the USGS have to track how glaciers have move or decreased in size over the last 150 years; in Glacier National Park, there were 150 named glaciers in 1850 while today there are 26 still persisting.
D.

Ice Caps - data collected by remote sensing by the Polar Science Center shows an overall decrease in Arctic sea ice volume since 1979 due to the positive feedback that less ice lowers the Earth's albedo, so the ocean absorbs more sunlight which n turn melts more ice.

3.

All introduced species are invasive species.

A.

True
B.

False

Correct Answer
B. False

Explanation
All invasive species are introduced species, but not all introduced are invasive. They need to have an adverse effect on their local ecology to be considered invasive.

A.

An organism that is introduced into a new ecosystem outside of its native habitat.
B.

An organism that has an adverse effect on people like harming humans.
C.

An organism that has an adverse effect on the new habitat like eating the food source of a native species.

Correct Answer
C. An organism that has an adverse effect on the new habitat like eating the food source of a native species.

6.

Adverse effects of invasive species presence includes a decrease in property values, decreased agricultural production, decreased tourism and recreation, and decreased ecosystem health.

A.

True
B.

False

Correct Answer
A. True

Explanation
