What it is	You study how Earth's materials, structures, and processes work by combining geology with physics — essentially learning the physics that explains what geologists observe in rocks, earthquakes, and planetary systems. This program differs from studying geology or physics alone because you'll apply physical principles directly to Earth science problems rather than studying them separately. It suits you if you're curious about how the planet works at a fundamental level and want flexibility to pursue either Earth science or physics-based careers.	This is a first-year science program that teaches you foundational chemistry, physics, and related subjects before you specialize. Unlike going directly into a single honours program, you spend your first year exploring different branches of physical science, then choose your final degree path — either a pure science degree or a combined science and engineering degree. It suits students who are strong in math and science but aren't yet sure whether they want to focus purely on theory or blend science with applied engineering.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.
