Our dynamic planet: Earth and life

On this page

The Earth appears constant and unchanging from a human perspective. Yet over the span of geological time, measured in billions of years, it is a dynamic system in which continents move slowly across its surface; mountain belts rise and fall; ocean basins are created and destroyed; the evolution of life itself occurs and all in concert to the pulse of the Earth’s internal energy: heat. But how did all this start? What are the Earth's origins and how does life form part of its pattern? This course tackles these fascinating questions and equips you with the intellectual tools to examine the evidence that is all around us.

Modules at Level 2 assume that you are suitably prepared for study at this level. If you want to take a single module to satisfy your career development needs or pursue particular interests, you don’t need to start at Level 1 but you do need to have adequately prepared yourself for OU study in some other way. Check with our Student Registration & Enquiry Service to make sure that you are sufficiently prepared.

What you will study

How did the Earth form and evolve into its present state? And how does life fit into this dynamic system? This course explores the structure of the Earth from core to atmosphere, and investigates how the Earth system works from a geological perspective. You will study how the geosphere, hydrosphere, atmosphere and biosphere all interact to produce the world we live in today.

The course is organised in two halves, based around two books. The first book, An Introduction to Our Dynamic Planet, investigates the solid Earth (or geosphere); its place in the Solar System; and the processes that have both shaped it in the past and continue to shape it today. After opening chapters on the structure and formation of the Earth and that mysterious time before the geological record, the Hadean, the book focuses on plate tectonics. There are separate chapters on processes at constructive and destructive margins and continental collision zones. These are all regions where the geosphere interacts with the oceans and atmosphere and where the geosphere is currently active. You’ll then look at the deep Earth and how that continues to affect the surface environment, with a final summary of the critical factors that make the Earth operate in the way it does today. All through this course, you’re continually reminded of the ways in which the geosphere interacts with (and reacts to) the atmosphere and hydrosphere.

The second half of the course is based on the book An Introduction to the Earth-Life System and examines the interactions and feedbacks between the atmosphere, hydrosphere, geosphere and biosphere. You will explore how the Earth’s surface environment is a complex interplay between these components. You will also be looking at the variable timescales over which these interactions take place: from the Wilson Cycle – dictated by plate motions operating over hundreds of millions of years – through ice ages of a few million years duration, to the effects of ocean and atmospheric circulation over periods of years, decades and centuries. You will investigate the astronomical controls of climate change; how they are recorded in sedimentary rocks; and the interaction between mountain building, erosion and climate change. You’ll also examine life itself: is it passive, or a force for change driving the environment towards further evolutionary development?

Throughout the course, your studies will be directed via a website. There will be additional activities, some based around your computer while others involve reading and analysis of sources in the published scientific literature.

Entry

This is a Level 2 course and you need to have a good knowledge of the subject area, obtained either through Level 1 study with the OU, or by doing equivalent work at another university. Exploring science (S104) and Maths for science (S151) would be ideal preparation.

You are also strongly advised to have already completed Geology (S276) and Planetary science and the search for life (S283) as both are essential preparation for this course.

We do not recommend that you start your Level 2 study with this course, as the content requires a familiarity with scientific language and concepts that are reasonably advanced. Although highly rewarding, it is a challenging course as it requires the ability to take a broad overview of an issue, drawing on evidence from a wide range of sources and science disciplines. It will also equip you with the skills and knowledge required to take on any of our current Level 3 Geosciences courses.

It is essential that you establish whether or not your background and experience give you a sound basis on which to tackle the course, since students who are appropriately prepared have the best chance of completing their studies successfully. The Science Faculty has produced a booklet Are You Ready For S279? to help you to decide. This can be viewed or printed from the Are you ready for science? website.  

If you have any doubt about the suitability of the course, please contact our Student Registration & Enquiry Service.

Regulations

As a student of The Open University, you should be aware of the content of the Module Regulations and the Student Regulations which are available on our Essential documents website.

If you have a disability

The study materials will be available on DVD-ROM in Adobe Portable Document Format (PDF). The course contains many complex diagrams and the most important of these may be described within the PDF e-texts. Components may not be fully accessible using a screen reader and mathematical, scientific, and foreign language materials may be particularly difficult to read in this way. The books are available in a comb-bound format. Written transcripts for the audio-visual material are included on the DVD-ROM. The course also involves drawing diagrams and plotting graphs which may be difficult for some students. You may be required to draw diagrams or to annotate by hand diagrams that you download, and then to use either a scanner or a digital camera to produce files of these diagrams for inclusion in your assessment. If you have severely impaired sight, you may need a sighted assistant to be able to make full use of the computer-based resources or complete some of the activities. Our Services for disabled students website has the latest information about availability.

If you have particular study requirements please tell us as soon as possible, as some of our support services may take several weeks to arrange. Visit our Services for disabled students website for more information, including:

  • help to determine your study requirements and how to request the support that you need  
  • Disabled Students' Allowances (DSAs)
  • using a computer for OU study
