The Earth is a massive puzzle, but there isn’t one way to solve it. Earth science looks into the past, present, and future of the planet. By studying the rocks, water, and air, we ask big questions and solve important problems.
If you love Earth science but aren't sure which major to pick, you’re not alone. While geology and environmental geoscience share the same roots, they lead to two very different missions.
Think of it this way: geology focuses on the history of the Earth, while environmental geoscience focuses on the health of the environment.
Earth Science Foundations
Both majors use the same toolkit to solve problems:
- Relative Dating: Reading the Earth’s history through layers of rock.
- Plate Tectonics: Understanding the forces that move continents.
- The Rock Cycle: Discovering how Earth recycles over millions of years.
- Environmental Care: Using science to manage the planet’s resources.
Good Earth science relies on:
- Evidence-Based Decisions: Using real data from the field.
- Systems Thinking: Studying how the whole Earth changes its systems.
- Communication: Teaching science to the public and policymakers.
Common Careers for Earth Science
Environmental Scientist/Geoscientist: Protect public and environmental health.
- Identify threats to environmental health.
- Design solutions to clean up the land.
Hydrologist: Manage the world's most precious resource: water.
- Study how water moves through Earth’s crust.
- Ensure that clean water is always accessible.
GIS Technician/Spatial Analyst: Map the world to solve spatial puzzles.
- Use advanced software to create digital maps.
- Track everything from environmental hazards to where minerals are buried.
Natural Resource Manager: Balance industry needs with conservation.
- Lead the use of forests, minerals, and rangelands.
- Work to ensure we use Earth's resources without destroying them.
Which Path Fits Your Interests?
Choose Geology if you want to focus on:
- Deep Research: Digging into the physics and chemistry of how Earth’s systems work.
- Resource Exploration: Finding petroleum, minerals, and metals.
- Rock Mechanics: Studying how solid rock bends, breaks, and supports massive structures.
- Applied Science: Mapping out the hidden parts of the Earth.
Choose Environmental Geoscience if you want to focus on:
- Data-Driven Decisions: Solving modern climate change puzzles.
- Policy & Law: Understanding legal frameworks that govern how we protect our air, water, and land.
- Sustainability: Leading conservation efforts to ensure we don't outpace natural resources.
- Advocacy: Creating awareness and communicating complex science to the public and policymakers.
The World is in Your Hands
The Earth is a massive puzzle, and your unique skills are exactly what we need to solve it.
Your next steps are simple:
- Start the Foundation: Enroll in either major to get your first taste of the Earth sciences.
- Meet the Mentors: Connect with our faculty to hear about current research in seismology, mapping, and conservation.
- Join the Community: Whether it’s the UAS/Drone Society or the Geology Museum, get involved and see where your curiosity leads.
