Document Summary

Choose 3 out of 5 medium length questions. Choose 1 out of 2 long answer questions. Geos126 has changed since last year, past exams before that will be slightly different. Australia has been covered by glaciers in the past. Climate does change significantly and sometimes over relatively short periods of time. Focus on not how much the temperature has changed but more of how fast it has changed (the rate of change). The distribution of organisms such as forams. Corals relatively high resolution for the last 10,000 years or so. Ratio of different isotopes found in the sedimentary record. The speed of growth of trees is a function of weather, especially trees in higher latitudes since the growth season is concentrated during summer months. Creates a short record which can be combined. Shows records of fires, frost, and droughts (anything that affects the trees ability to grow biomass)
