• Paleocene-Eocene thermal maximum
• NAIP - north Atlantic igneous province
• Each layer is a single basaltic flow
• Forams: algae like organisms
• Drastic change in population
• Life recovers
• Deccan traps: volcano area
• Good record of volcanic eruptions in last hundred years
• Small eruptions don’t tend to leave evidence on surface of earth
• Arguing either for or against
• Should western countries tell developing countries to take a different pathway in order to curve
greenhouse gases
November 15th - science skills lecture
November 22nd - ERS111 drop in session
• Material erosion, brought into ocean, gets subducted or becomes mountain and cycle continues
• Helps to balance the climate
• Once it is cemented together it is a rock
• Water, air, and ice are movements of sedement
• Surface area is what interacts with weathering
•
• Ice - enlarges the joints and cracks
• Important in terms of climate
• Interaction with chemicals in the atmosphere combined with rock particles
• Carbonates release more carbon dioxide
• Helps to negate big scale climate changes
• Homogenous = made of one thing
• Heterogenous- made of multiple things
