Document Summary
The sun has always been the strongest single factor controlling earth"s. Chapter 6 hw instructor rick di maio. Answer these questions with a brief response total time: 90 minutes. 1) from sec 6. 1: name and describe two major controls (climate forcing"s) that have caused historic climate changes (before mankind). climates. The second factor that has caused historic climate change is milankovitch. Cycles which act to alter the total amount of solar radiation affecting season intensity: from sec 6. 6: volcanism during the cretaceous period added massive amounts of co2 to the atmosphere thus driving up global temperatures. Describe two factors that removed large amounts of carbon during this period. The highest levels of co2 were due to volcanism, but the earth naturally got rid of the massive amounts of co2 because of the plants. The amount of plants naturally balanced out the levels through natural processes. Cretaceous period that tiny coccolithophore shells drew down many gigatonnes of co2 from the atmosphere.
