Geology (GEOL)

Our understanding of Earth evolution is mostly based on the study of minerals, rocks, soils, fossils, and geological structures.

Using examples from Atlantic Canada, students examine surface and subsurface processes (e.g., weathering and erosion involving gravity, wind, waves, river currents and ice; groundwater flow; tectonics), and consider geological time, history, resources and hazards. Classes 3 hrs. and lab 3 hrs. a week.
