Question

Hapter Exan 1) How does accuracy of dlimate reconstruction generally change with respect to present (1pts) day? O Accuracy decreases with increasing time before present. Accuracy increases with increasing time before present. O Accuracy is constant. There are many other variables that have to be taken into account. 2) Which of the following has been analyzed using historic art? (1pts) Amount of aerosols (particulates) with regard to the color of the sunset High temperatures with regard to how people were dressed D Ocean conditions with regard to how many boats appear in artwork d None of the above 3) The tree growth index is a ratio that includes which of the (1pts) following? Actual tree growth ring width Expected tree growth ring width based on tree's age Tree height Both a and b are correct.

Explanation / Answer

1) Accuracy decreases with increasing time before present beacause as the time span increases the evidences got vanish.

2) Amount of aerosols present with regrad to the colour of sunset. As the scientists found that the relative amounts of red and green along the horizon in the paintings indicate the amount of particulate present.

3) Actual tree growth ring width because tree-ring width was strongly correlated with rainfall and wind data, indicating that annual tree growth was closely related.

4) Run a multi regression analysis. Until now linear regression analysis were done in order to reconstruct the pact climate conditions using only one parameter at a time. Now we are using multi-attribute models and predict the climate from tree ring widths, height increments, maximum latewood densities and stable carbon isotope analysis.
