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	Earth Sciences is a study of rocks, minerals, Earth's structure, and environmental systems — how the planet works and how humans interact with it. The program includes a co-op work placement component, meaning you alternate between classroom study and paid work terms at companies or organizations in geology and environmental fields. It suits students curious about natural systems and interested in learning through hands-on experience in the workplace.	You study the structure, composition, and processes of the Earth's rocky layers and landscapes, combining geology with physics and geography. Physical geology focuses on how rocks form, break down, and move, rather than on finding mineral deposits or fossils. The co-op option lets you do paid work terms with industry or research employers alongside your studies, giving you real experience in the field.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.
