What it is	You study how Earth's systems work — its atmosphere, weather, climate, oceans, geology, and space — using physics, chemistry, and math. This program lets you do paid work terms with employers alongside your courses, giving you real experience in research labs or environmental organizations. It suits people curious about how the planet functions and wanting to test their skills in the field before deciding on a career.	You study how Earth's climate and environment work, using chemistry, physics, and geography to understand weather systems, ecosystems, and human impacts. This program combines natural science with social geography, so you examine both the physical causes of environmental change and how people and communities respond to it. It suits students curious about climate science who want hands-on experience through co-op placements alongside their coursework.	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.
