PHYS 106L Lecture Notes - Lecture 16: Axial Tilt
Document Summary
Data has been collected for 200-500 years, but can be traced back millions of years. How close to or far from the sun the earth gets. Dependent on how much ocean is exposed. How climate has changed and how the plants have responded to it. 1: looking for what could have affected climate in the past. Plot has pieces that are embedded in main diagram. 7: repeat what you did with 1 with breaking up chart. 9: relationship between volcanic eruptions and temperature. If we had no tilt, there would be no seasons. Smaller tilt = smaller magnitude of seasons. Larger tilt = greater magnitude of seasons. 12: look at question 2 of lab 4 and figure 4. 1. Pick a few dates and draw vertical lines. 17: relationship between insolation and ice cover. 18: what is the relationship between carbon dioxide and ice cover. 20: actual tree rings, identify every 10th ring and match the patterns between the charts.
