Essay plans: Go over your notes and read around the subject a bit!
A structured way of doing this is by identifying the 1A tripos questions that relate to the Michaelmas and Lent term of the course (which you can access through Moodle), and use these essay titles to construct detailed essay plans. Where you can’t think what you would say, head back to the notes and then onto relevant textbooks to find the information you need and to furnish your answers with more quantitative detail and, especially, real-world examples of the processes you are describing.
Plan these essays last few years of tripos on Lent term material and bring them to the first supervision. Focus on :
 Using the concept of global energy balance, account for the global average temperature at the Last Glacial Maximum (LGM). How can you reconcile your account with the Milankovitch theory of the ice ages, given that global average insolation at the LGM was similar to the present day?
 Outline the major patterns in animal biodiversity during the Phanerozoic. To what extent are geological events responsible for these patterns?
 Contrast and explain the different lithological properties and sedimentary structures of limestones and sandstones. Why are these rock types distinct?
 What are the main types of sedimentary delta, and what are the physical parameters that control delta morphology and internal structure? How do you recognize a deltaic sequence preserved in the geological record?
 Discuss the factors that control the oxygen isotope ratio of calcite in the shells of marine foraminifera. How have oxygen isotopes been important for testing the Milankovich hypothesis of glacial cycles?
