Strongly recommended subject: ENG4U Alternative Offers You will receive an offer of admission to only 1 program. Your highest listed choice is considered first when you indicate more than 1 Brock program on your application. If you are not eligible for your first choice, your subsequent choices will be considered in your indicated order of preference. In most cases: If you apply to only 1 Brock program but do not qualify, you will be considered for an alternative or related program. If you apply but are not admitted to a co-op program you will automatically be considered for the regular, non-co-op program.

What it is	Environmental Science combines the study of living systems and Earth's physical processes — like climate, water, and soil — to understand how natural environments work and respond to human activity. Unlike a program focused only on biology or only on geology, this degree integrates both to tackle real-world environmental problems. It suits students interested in conservation, resource management, or environmental consulting who want a broad scientific foundation rather than specialization in a single discipline.	This program lets you study pure science in one of four areas: biology, chemistry, physics, or a mix of these subjects. You'll take foundational courses in your chosen field and build toward specialized upper-year courses. It suits students who want a strong grounding in how the natural world works, whether they're planning to go further in science or use that knowledge in other directions.	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.
