Past Climates and Climate Reconstruction Part 1 Climate and Interactions among Spheres What interactions among the spheres of the Earth Systems can you observe in the following photos Explain your answer 1 Tectonic plates clashed together to form 3 Coral reefs protect and give fish homes the hilly area and rain formed the clouds causing the stream to protect them from erosion People hunt the fish for food 2 Humans planted seeds to create trees 4 Rain clouds form and rain into the to grow ocean Wind pushes the tide onto the coast causing waves Part 2 Tree Ring record The file Tree Ring Record xls contains annual tree ring with measured on some tree Calculate the annual width anomaly Plot the width anomaly In the same plot add a graph showing five year running mean Based on this graph complete the following table Tree Age Range Relative Thickness thick or thin 1400 1470 1500 1550 1570 1590 1590 1620 1750 1776 1850 1889 thin thick thin thick thick thin How does tree ring thickness from the specimen in class relate to the record of past moisture change for the continental US shown below Be specific and use examples from your table to support your answer The years with more moisture have thicker tree rings The record of dryer and wetter environmental conditions created from the tree rings does not match that from the figure exactly Hypothesize two reasons why these records might not match exactly There are other factors that can affect tree thickness other than moisture Human interaction is one Trees can affect it as well as other types of water or other natural effects that occur
