Question 5

How is ocean acidification possibly linked to increased anthropogenic emissions of carbon dioxide (CO2)?

Accepted Answer

A) Oceans may absorb much of the rising concentrations of rising carbon,as dissolved CO2 mixes with water to form carbonic acid (H2CO3). 
B) Thermohaline circulation exchanges carbon between surface dissolved organic carbon and deep layers of dissolved inorganic carbon. 
C) Increased photosynthetic activity in phytoplankton resulting from increased atmospheric CO2 concentrations results in acidification due to a complex chemical reaction during plant decay. 
D) Atmospheric CO2 combines with atmospheric moisture forming a light carbonic acid forms (H2CO3),that is precipitated over the worldʹs oceans.

Question 6

A definitive link between climate change and extreme weather events has been established.

Accepted Answer

A) True 
 B)False

Question 7

Which of the following accurately describes the use of tree rings for studying past climates (dendroclimatology)?

Accepted Answer

A) The width of annual tree rings indicates the climatic conditions; wider rings suggest favorable conditions,whereas narrower rings suggest harsher conditions. 
B) Because most trees only live 60 to 100 years,dendrochronology can only serve as a climate record for recent history and are primarily used to supplement instrument data. 
C) The age of trees can be determined by tree ring analysis.By establishing the age of long -lived trees,one can determine the climate conditions of the area the year the tree sprouted. 
D) Dendrochronology is primarily used in the tropical regions,where one can easily correlate a tree speciesʹ age with the climatic conditions there.
