Students consider the Earth's major types of landforms such as mountains, rivers, plains, hills, canyons, oceans and plateaus. Student teams build three-dimensional models of landscapes, depicting several of these landforms. Once the models are built, they act as civil and transportation engineers to design and build roads through the landscapes they have created. The worksheet is provided in English and Spanish.

Compiled and modified for instructional use by: Kate Darby, Western Washington University In 1887, Robert Towne built a metals smelter two and a half miles northwest of El Paso, Texas, across the river from Ciudad Juarez in Mexico and across the state border from several small towns in New Mexico. The smelter, which processed metal ore from regional mines, was quickly acquired by ASARCO (American Smelting and Refining Company) and became an important visual and economic institution in the region. In 1967, following the mantra of environmental regulation at the time—"the solution to pollution is dilution"—ASARCO erected what was then the tallest smokestack in the world: an 828-foot structure visible from much of the region. While the facility provided jobs to many in the region and produced metals important for a range of manufacturing and consumer products, by the 1970s, residents and scientists began to question the other products from the smelter—especially heavy metals pollution.

Compiled and modified for instructional use by: Lisa Phillips, Illinois State University, llphill@ilstu.edu On September 10, 2012, several million southern California residents reacted with alarm to an unfamiliar noxious scent. The Air Quality Management District officials in the Los Angeles region were initially at a loss to determine the odor's source. Investigators from Ventura to Palm Springs looked for toxic spills, sewage plant leaks, and gas line breaks—all for naught.
The smell's origin was the Salton Sea more than 150 miles away and not usually upwind. The smell of an algal bloom and subsequent massive fish kill released odor molecules redolent with the stench of environmental decay.

This case study is an examination of the chemical and sensory impacts of a variety of environmental issues including sand mining, leaking underground gasoline storage tanks (LUSTs), and a railroad.
Wedron is a small, unincorporated town of approximately 100 residents in north central Illinois. A large sand mine has been in operation on the south and west sides of the town for many decades, and the mine property includes several abandoned and active pits, a processing plant, and a train car loading facility. Railroad tracks are located along the east side of town as is a grain elevator (storage and loading facility).
The following information was obtained from the US EPA web site about Wedron, personal visits to the town, and published news articles.

Two or three weeks of the course are dedicated to studying diagenesis. Lectures start with a general definition of diagenesis, the range of conditions under which it occurs, and examples of diverse diagenetic environments and features. I use rice crispy cereal and rice crispy treats to introduce cement (the marshmellow is the cement that "glues" the rice krispies together). I also incorporate basic hydrogeology to show how pores filled with (or partially filled with) groundwater provide both the space and the material for cementation. As part of this lecture, I show the students various rock samples and photomicrographs in which they can see cement examples. I outline the different cement minerals and shapes and how they can be used to interpret past diagenetic conditions (eg., gravitational "pendant" calcite cements indicate that the host sediment was once in a vadose zone with groundwater rich in calcium and carbonate). I also discuss types of pores during these lectures and the ways that pores form. We also discuss criteria for recognizing cements. After two one-hour lectures about cements, we have a lab exercise in which the students are given ~10 samples (including hand samples and thin sections) and asked to sketch and describe the cement types. The next one-hour lecture focuses on neomorphic processes and their products, including replacement, recrystallization, and polymorphic transition. As part of the lecture, we look at photomicrographs and hand samples that illstrate various neomorphic features, such as replacement dolomite and replacement chert. We establish criteria for distinguishing cements from neomorphic fabrics. This lecture is followed by a lab exercise that presents the students with ~10 rocks and thin sections and asks them to sketch and identify neomorphic fabrics. This lab is follwed by another one-hour lecture on compaction features, dissolution evidence, and determining paragentic sequences. If I am short on time, that is all I do for diagenesis. However, ideally, I continue with a lecture focused on the "dolomite problem" and some case studies of other types of diagenesis, as well as a third lab assignment that combines cementation, neomorphism, compaction, dissolution, and paragenetic sequences. As part of this section, I also try to incorporate examples of methods other than petrology (eg., fluid inclusion studies, stable isotope studies, dating) that are used for diagenetic studies. Later in the course, we take several field trips in which the students examine diagenetic features.

In this activity, students view a Quicktime video animation based on data from the North American Volcanic and Intrusive Rock Database (NAVDAT) to learn about the history of volcanism in the western U.S. during the last 65 million years. Students are guided through the complex data-rich animation with a series of instructions and study questions which highlight time-space-composition relationships and link to plate tectonics.
