i)16O and 18O are two different isotopes of oxygen. What is ONE IS TRUE about 18O? it less easily evaporated than 16O it is more volatile and reactive than 16O it is lighter than 16O it is more commonly occurring than 16O II) Ice core samples taken from Antarctica have been used to estimate changes in surface temperatures and the atmospheric concentrations of carbon dioxide and methane. This data indicates that when the temperature is relatively warm, the amounts of carbon dioxide and methane are ___________ Select one: relatively low (negative correlation) sometimes high, sometimes low (no correlation) relatively high (positive correlation) III) The answer to the previous above question indicates that ___________ . Select one: high atmospheric concentrations of carbon dioxide and methane might lead to warmer temperatures high atmospheric concentrations of carbon dioxide and methane might lead to cooler temperatures there is no relationship between temperature and the atmospheric concentrations of carbon dioxide and methane none of the above, because climate scientists have been unable to establish a clear cause and effect relationship between the amounts of the greenhouse gases carbon dioxide and methane and changes in temperature
i)16O and 18O are two different isotopes of oxygen. What is ONE IS TRUE about 18O?
it less easily evaporated than 16O
it is more volatile and reactive than 16O
it is lighter than 16O
it is more commonly occurring than 16O
II)
Ice core samples taken from Antarctica have been used to estimate changes in surface temperatures and the atmospheric concentrations of carbon dioxide and methane. This data indicates that when the temperature is relatively warm, the amounts of carbon dioxide and methane are ___________
relatively low (negative correlation)
sometimes high, sometimes low (no correlation)
relatively high (positive correlation)
III)
The answer to the previous above question indicates that ___________ .
Select one:
high atmospheric concentrations of carbon dioxide and methane might lead to warmer temperatures
high atmospheric concentrations of carbon dioxide and methane might lead to cooler temperatures
there is no relationship between temperature and the atmospheric concentrations of carbon dioxide and methane
none of the above, because climate scientists have been unable to establish a clear cause and effect relationship between the amounts of the greenhouse gases carbon dioxide and methane and changes in temperature
