Learn the Fundamentals of Geological Science
Understanding Earth Science is important to many industries, from mining to meteorology and agriculture to oceanography. This will teach you about the planet you live on; and lay a valuable foundation for working in any of these industries, or progressing to study a certificate, diploma or higher qualification.

- Explain different practical applications for a knowledge of geology
Geology is the study of the earth, the rocks, the materials from which the earth is made, the structure of those materials, and the processes which cause them to change over time. It is concerned with the structure of the earth at both the surface level and beneath the surface.
Geology also overlaps with other earth sciences like hydrology and climate science. An understanding of geology not only helps us to understand the historical context of the earth’s materials and formation but also uses that knowledge to help inform us about what we might expect in the future.
Studying geology has practical relevance in the real world in diverse ways, for example:
- Understanding and managing groundwater
- Informing us how to appropriately manage mining
- Providing insight into geologic natural hazards e.g. landslides, earthquakes, volcanic eruptions
- Understanding and predicting seismic activity
- Determining appropriate engineering work e.g. in construction of dams, infrastructure, buildings
- Helping to locate underground deposits of specific rocks and minerals
- Enabling knowledge of the effects of past episodes of climate change on the earth
- Adding to our knowledge of how the earth formed and plate tectonics (movement of the plates on the earth’s crust)
