The word geology comes from the Greek 'Geo', the Earth, and 'Logos', the study of.
By the end of this section you should be able to:
- examine evidence for the big bang;
- describe the formation of the universe;
- outline how seismic refraction can reveal the layered structure of our planet.
- identify how we can calculate the age of the earth
