Along with fossils in sedimentary rock, what other evidence do geologists use to infer what paleoclimates were like?

• grass

• pollen

• amber

• trees

Besides Antarctica, what other landmass has the other continental glacier?

• Canada

• Russia

• Arctic

• Greenland

Air bubbles trapped in ice cores are used to infer paleoclimates. One atom they study is oxygen isotopes and the ration between oxygen-16 and oxygen-18. What type of conditions tend to produce more oxygen-18?

• rainy periods

• warmer periods

• dry periods

• colder periods

Along with the oxygen isotope ratios, what other molecule do we relate with warmer temperatures?

• increased carbon dioxide

• decreased carbon dioxide

• increased carbon-14

• decreased carbon-14

Trees tend to grow more during warm years, what is the weakness in using trees to learn about paleoclimates?

• Trees are new in the geologic record

• Tree growth is too unpredictable

• Not all trees have rings

• Trees can only live up to 5000 years
