Strength and deformation of rocks.
Intraplate volcanism.
Core dynamics and geomagnetism.
Earth’s evolution through Hadean, Archean, Proterozoic and Phanerzoic.

Learning Outcomes

Subject-specific Knowledge:

To understand the processes by which heat is transferred within the solid Earth.
To understand the physics behind convection in the Earth.
To acquire knowledge and understanding of the structure and composition of the Earth across different geological timescales.
To acquire knowledge and understanding of Earth materials.
To understand the physics and nature of mantle plumes, subduction processes, and intraplate volcanism.
To understand the origin of the Earth’s magnetic field and the related dynamics of the Earth’s core.
The evolution of tectonics throughout the long-term history of the Earth.

Subject-specific Skills:

Providing key insight and understanding of the physical processes involved in Earth dynamics on a range of skills.
Solve numerical problems using both computer-based and paper-based techniques.
Critically evaluate the assumptions and uncertainties inherent in a model or analysis.
Make simplifying assumptions to enable analysis of a complex geological problem or situation.
Acquire the skills to synthesise data from a variety of sources.
Acquire the skills to analyse, evaluate and interpret geophysical and geological data.

Key Skills:

Develop problem-solving skills, initiative and persistence in tackling unfamiliar and challenging questions through supervised practical work and summative assessments.
Develop discussion and presentation skills.
Develop skills to critically evaluate, and review work with colleagues through discussion.
Evaluate and reflect on assumptions and uncertainties in analysis through supervised practical work and summative assessments.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

The module is delivered through a mix of lecture and practical sessions, supported by lecture slides, lecture notes, additional supportive reading and web-based material.
The practicals provide opportunities to apply principles, concepts and theory to case studies and practical examples.
Guidance on preparation, key and exam skills is provided.
