Thematic Sequences

The Geology Department offers three thematic sequences; Oceanography (TGLG-1), The Water Planet (TGLG-2), and Plate Tectonics (TGLG-3). Please contact Jonathan Levy (9-1947 or levyj@muohio.edu) to enroll or to get more information.

Oceanography, TGLG-1

This sequence provides an appreciation of the critical importance of the oceans to the functioning of our planet. Oceans dominate the surface area of the earth, and they are critical to the maintenance of a habitable planet. This sequence examines what we know about the oceans and how the oceans are an integral part of the Earth's ecology. In Tier 3, students engage in first-hand field studies, the ways that we study the oceans.

Tier 1. Choose one of the following:
GLG 111 The Dynamic Earth (3 hours)
GLG 121 Environmental Geology (3 hours) GLG 141 Geology of National Parks (3 hours)

Tier 2
GLG 244 Oceanography (3 hours)

Tier 3
GLG 413 Tropical Marine Ecology (5 hours)

Generally, Tier 1 courses are taught every semester; GLG 244 is taught every year. GLG 413 is taught as a two-week field course during the summer in the Bahamas, Florida and the Caribbean. This course requires summer registration of 5 credit hours and a travel/housing meal surcharge of approximately $600. GLG 413 is generally offered every summer.

The Water Planet, TGLG-2

This thematic sequence provides an introduction to the essential role water plays on Earth with respect to other Earth systems and in supporting life on Earth. The origin of water is examined along with water’s physical and chemical characteristics, how they combine to make life possible on the continents and in the oceans, and details concerning the hydrologic cycle. Over 97% of all water on Earth is in the oceans, the focus of Tier 2. In Tier 3, freshwater systems are emphasized. Depending on the option taken, this tier introduces economic, legal and political ramifications of water use in the US and globally and examines in detail freshwater systems including groundwater, surface water or lake ecosystems.

Tier 1. Choose one of the following:
GEO 121 Introduction to Physical Geography (3 hours) GLG 111 The Dynamic Earth (3 hours)
GLG 121 Environmental Geology (3 hours)
GLG 141 Geology of National Parks (3 hours)

Tier 2
GLG 244 Oceanography (3 hours)

Tier 3. Choose one of the following:
GLG 307 Water and Society (3 hours)
GLG 335 Ice Age Earth (3 hours)
GEO 425 Hydrogeography (3 hours)
GLG 408 Introduction to Hydrogeology (4 hours)
BIO 463 Limnology (3 hours)

Generally, Tier 1 courses are taught every semester; GLG 207, 244 and 408 and ZOO 463 are taught every year. GEO 425 is taught every other year.

Plate Tectonics, TGLG-3

This thematic sequence provides an overview of how plate tectonics shapes the Earth, including the creation of landforms, natural hazards, and economic reservoirs. Following an introduction to the primary features in Tier 1, courses in Tier 2 examine physical principles underlying movement of Earth’s surface and effects on rock types, chemistry, fabric, and layering. Tier 3 provides an opportunity to apply the general knowledge and physical principles from the previous tiers to more complex, real- world situations. These courses illustrate how local studies can provide insight into global processes.

Tier 1. Choose one of the following:
GLG 111 The Dynamic Earth (3 hours)
GLG 121 Environmental Geology (3 hours) GLG 141 Geology of National Parks (3 hours)

Tier 2
GLG 261 Geohazards and the Solid Earth (3 hours) GLG 301 Sedimentology and Stratigraphy (4 hours)

Tier 3. Choose one of the following:
GLG 322 Structural Geology (4 hours)
GLG 461 Geophysics (3 hours)
GLG 467 Seismology (3 hours)
GLG 492 Global Tectonics (4 hours)

Generally, Tier 1 courses are taught every semester; GLG 261, 301 and 492 are offered each Spring; GLG 322 is offered every Fall; GLG 461 and 467 are taught in alternating Fall semesters.
