If you're curious about our planet and interested in discovering solutions to environmental issues, then our geology courses could be for you.

Looking for something other than a qualification?

The majority of our modules can be studied by themselves, on a stand-alone basis. If you later choose to work towards a qualification, you may be able to count your study towards it.
