Geologic processes both rapid (earthquakes and landslides) and slow (mountain building and sea level rise) are intimately linked with sustaining the diversity of life on the planet. This course examines processes linked with the flow of energy and mass between the atmosphere, geosphere, and biosphere. Laboratory exercises, and field work provide authentic experiences to develop the skills needed to observe and model processes shaping our environment. Problem solving during class time fosters critical thinking and classroom debates between larger teams focus on research and communications skills by examining current issues in geosciences such as building and removing dams, and the science surrounding global climate change.

This course provides those interested in any aspect of the Earth Sciences with the base necessary to understand the physical and chemical properties of Earth Materials (e.g. minerals and rocks). The primary focus of this course is to understand the concept of optical and chemical mineralogy in the broad context of the geosciences, but the environmental and human health applications of Earth Materials will also be explored. Our primary tools will be field and hand sample observations, petrographic analysis of rocks and minerals in thin section, and x-ray and electron beam based analytical techniques.

Sediments and sedimentary rocks cover most of the Earth's present surface. Sedimentology encompasses the study of the origin, transport, deposition, and lithification of sedimentary rocks and is critical to accurate interpretation of the geologic rock record. Observations of modern sedimentary processes illuminate past environments; sedimentary strata record evidence of mountain building and seismic activity, glacial advances and paleoclimate cycles, and preserve the fossil record. Natural resources including groundwater, coal, and petroleum are found in sedimentary rocks. Society is impacted by sedimentary processes in popular human habitats including coastlines and flood plains. Readings and discussions build students' familiarity with topics such as sediment transport, stratigraphy, and modern and ancient depositional environments. A semester-long project, laboratory exercises, and mandatory field trips emphasize field methods, rock identification, and data collection, analysis, and interpretation.

The Earth is a dynamic planet where change is driven by processes that operate within its interior and on its surface. In this course we study these processes as well as interactions between the solid earth, the hydrosphere, the atmosphere, and the biosphere that together produce the environment we live in and influence our daily lives. Topics covered include the origin and history of the Earth, plate tectonics, deep time, the materials that make up the solid earth, the distribution of earthquakes and volcanoes, hydrology, landscape evolution, and global climate. Hands-on work in class and laboratory sessions, along with project work, and local field trips, provide opportunities to develop deeper learning of key concepts and to hone observational and analytical skills.

The geologic record, covering 4.6 billion years, provides us with a long-term perspective of the Earth system and how it operates over time scales much longer than human history. Using Wellesley’s extensive rock and fossil collection, geologic data sets and journal articles, we will reconstruct and interpret Earth's eventful past, including periods of mountain building, dramatic climate changes, and the evolution and extinction of life on our planet. This class should give students an understanding about deep time and that we live on an ever changing planet. The lab component of this class will be entirely in the field where we will visit key geologic outcrops that represent a large part of Earth history. During three weekends throughout the semester (one half day, one full day and one 1.5-day trip) we will explore the regional geology in New England and Upstate New York. The majority of the field work will take place during a 6-day field trip to the southwestern United States in mid-May between the last day of finals and commencement. This class fulfills the geosciences major requirement.

The Earth is an ocean planet. Covering 71 percent of the Earth's surface and holding 97 percent of the Earth's water, the oceans are perhaps our planet's most distinctive feature. This course will address fundamental questions about the oceans such as, why do we have oceans and ocean basins? Why do we have ocean currents? How have the interactions among physical, chemical, and biological processes produced the ocean we have today? Why should we strive to learn more about the oceans, and what are the links between the oceans and Earth's climate? In-class exercises, case studies, and data analysis will emphasize fundamental oceanographic processes and problem solving skills. A mandatory field trip to the coast will allow students to explore coastal processes in action.

The metamorphic and igneous rocks that underlie much of New England record a complicated history of mountain building, subduction, and failed rifting dating back to at least 1.2 Ga. This course will explore this history from the earliest orogeny to the assembly and destruction of Pangea. To guide our exploration, we’ll focus on three key questions:

1. How and why do igneous and metamorphic rocks form, and how are these processes related to plate tectonics?
2. How can we use the geochemistry and structural geology of igneous and metamorphic rocks to reconstruct past tectonic events?
3. How are stable cratons formed and why do they remain stable?

There will be one weekend day trip and one overnight weekend trip.
