The Evolving Earth

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

• Discuss in detail the major events in Earth history that shaped the planet’s climate, oceans, atmosphere, and biosphere.
• Develop critical thinking skills by assessing and interpreting different published models of Earth’s past environmental and climatic changes.
• Synthesise and evaluate published data from multiple sources to explore uncertainties in our understanding of Earth system evolution
• Apply a range of methods, including Earth system models and statistics, to analyse the evolution of the Earth.
• Evaluate competing theories of Earth evolution using the latest research and quantitative approaches.
• Work independently to complete a research project that uses wider reading and modelling techniques to explore a key aspect of Earth history.

This module explores the dynamic evolution of the Earth through the lens of geological, geochemical, biological, and climatic changes. Over 24 hours of lecture and discussion sessions and 24 hours of practical sessions, students will develop an understanding of the processes that have shaped Earth system over time, and the quantitative tools that can be used to test and reconstruct them. In this module we will investigate the dynamic processes that have shaped Earth’s evolution and its place within the solar system. Key themes include planetary formation and differentiation, the development of Earth’s internal and surface systems, and the interactions between the solid Earth, biosphere, atmosphere, and hydrosphere. We will examine the role of biological and chemical processes in shaping global cycles, including shifts in ocean chemistry, climate transitions, and changes in atmospheric composition. We will analyse patterns of environmental change, mass extinctions, and planetary-scale disturbances in the context of Earth’s long-term habitability. We will further discuss comparative planetary evolution to provide broader perspective on Earth’s history and its place in the broader solar system and beyond. Throughout the course, students will gain hands-on experience with Earth system models and quantitative methods, applying these tools to reconstruct past environments and explore key transitions in Earth history. The assessment will be centred on 1) a short literature review synthesising and evaluating key data relevant to Earth system evolution and 2) an independent research project, culminating in a research presentation where students will integrate wider reading with modelling approaches to investigate the evolution of the Earth system.

Formal Lecture and Discussion Sessions: 12 x 2-hour lecture and discussion sessions will provide the background and evidence underlying key topics relating to the evolution of the Earth. Generally, the first part of each session will be a lecture, followed by a discussion component where students engage in debates and problem-solving exercises related to the lecture material. Students are expected to review material before each session to participate fully. Practical Sessions: 12 x 2-hour practical sessions will provide hands-on experience with Earth system modelling and other quantitative methods. Students will apply modelling tools and techniques to explore key transitions in Earth’s history and develop the practical skills necessary for their research projects. These sessions will be designed to reinforce the theoretical material presented in the lectures and support the development of students’ independent research capabilities. Guidance will be provided throughout the practical sessions, with an emphasis on fostering problem-solving and analytical skills in a collaborative environment. Background reading and independent research are essential, and a list of wider reading materials will be provided. Time will also be allocated for preparation of the research project, and support will be available for students with additional learning or teaching needs.
