Physical Geology

Course Description

GLY2010C – Physical Geology is a 3- or 4-credit (varies by institution), integrated lecture-and-laboratory course covering the materials and processes that shape the solid Earth. Students learn the principles of plate tectonics — the unifying framework of modern geology — along with the rock cycle and rock-forming processes (igneous, sedimentary, metamorphic); minerals and their identification; weathering, erosion, and soil formation; surface processes (rivers, glaciers, deserts, coastal systems, mass wasting); volcanoes and earthquakes; geologic time; and Earth's resources (water, energy, mineral). Most institutions integrate substantial Florida-specific content: Florida's karst landscape, sinkholes, springs, the Floridan Aquifer System, beach erosion, coastal change, and sea-level rise.

The course sits within the Florida Statewide Course Numbering System (SCNS) under Geosciences > Geology and is offered at approximately 18 Florida public institutions. GLY2010C satisfies the natural-science (laboratory) general-education requirement at every Florida public institution. The integrated "C" format means lecture and laboratory meet as a unified course; students apply concepts directly through hands-on lab exercises (mineral and rock identification, map reading, fossil identification, geologic-cross-section interpretation).

GLY2010C is the standard introductory geology course for both non-majors satisfying gen-ed requirements and geology, environmental science, and earth-system-science majors beginning their disciplinary preparation. The course is widely available in face-to-face and hybrid formats; fully online sections are less common because of the lab component, though some institutions offer "lab kit" online options where students receive a physical specimen kit. Most institutions also include field trips to local geological sites — Florida offers excellent springs, karst features, beach systems, and shallow-water marine environments for field study.

Special Information

Articulation and Transfer

GLY2010C articulates to all Florida SUS institutions and satisfies the natural-science (laboratory) general-education requirement at every Florida public institution. The course is the standard introductory geology course for both gen-ed and major preparation. Transfer of GLY2010C as part of a geology major sequence requires a grade of C or higher at most institutions.

Florida-Specific Content

Most Florida instructors integrate substantial Florida-specific geology — the karst landscape, sinkholes, the Floridan Aquifer System, springs, beach erosion, sea-level change. Florida is geologically distinctive in being almost entirely underlain by carbonate rock (limestone and dolomite) deposited as marine sediments over the past 65 million years; nearly all of Florida's "geology" is shallow-water marine and coastal. The state has only minimal exposed igneous, metamorphic, or hard sedimentary bedrock. This makes Florida an unusual but compelling case study for understanding sedimentary geology, groundwater geology, and coastal processes.

Field Trips

Most Florida physical geology courses include at least one field trip to local geological sites — springs, sinkholes, beaches, river systems, or other accessible features. Field trips are typically required and may incur additional costs (transportation, park admission). Online sections may substitute virtual field trips using Google Earth and instructor-curated resources.

Course Format and Workload

GLY2010C is typically a 3- or 4-credit integrated lecture-and-lab course. The 4-credit version generally meets 3 hours of lecture and 2–3 hours of lab per week; the 3-credit version typically meets 2 hours of lecture and 2 hours of lab. Credit and contact-hour structures vary by institution; most Florida public institutions offer GLY2010C as 3 credits with integrated lab (60 contact hours), but 4 credits (75 contact hours) is also common. Expect: weekly lecture; weekly laboratory exercises (mineral/rock ID, map reading); 2–4 unit exams; one or more field trips (may be required); a comprehensive final exam. Out-of-class workload typically runs 6–9 hours per week.

Course Code Variations

Florida institutions title this course "Physical Geology," "Introduction to Physical Geology," or "Geology of the Earth." The course is most commonly 3 credits with integrated lab (the "C" form); some institutions offer a separate-lab structure (GLY2010 + GLY2010L). The credit-hour structure varies: at some institutions GLY2010C is 4 credits; at others it is 3 credits. Students transferring should verify credit and lab-component equivalency.
