Go outside and find an outcrop—a roadcut, cliff face, or other site where rocks are exposed. These are ideal places for practicing field geology. Professor Cotter gives tips on safety, maps, tools, and techniques. A notebook and careful record-keeping are essential. Amateur geologists can make important discoveries, so field geology is your chance to advance knowledge while enjoying the outdoors.

Mining is one of the oldest applications of practical geology. Find out how metals are classified and how most are associated with igneous and metamorphic deposits. Some metals, like gold, can be mined in a pure—"native"—state that requires little processing. Discover how and where to go prospecting for gold, using the panning process perfected by the Forty-Niners in California.

Since 2006, the number of landlines has decreased, while the quantity of mobile phones and other communication devices now outnumber the entire human population. Explore how engineers have created the cellular systems required to manage large numbers of calls at once, even as the user moves from place to place.

Explore the earliest electronic computers, including Charles Babbage's Analytical Engine. Although Babbage was not able to completely build it out before his death, his "engine" was based on the same four components that define computers today—input device, some type of memory to store data and temporary calculations, a calculating processor, and an output device.

Investigate glaciers, which now cover about 10% of Earth's land area; 25,000 years ago, they covered 30%. Learn how to spot evidence of past glaciation—from sculpted valleys in Yosemite National Park, to the cliffs at Vicksburg, Mississippi (which formed far from glaciers), to Minnesota's 10,000 lakes. Dig into the physics of glaciers: how they develop and the forces they exert.

Geomorphology is the study of landscapes and their individual landforms. Learn the five major influences on landscape formation. Use this background to tour the United States, which is a remarkable laboratory of geomorphology with features such as the Appalachian and Rocky Mountains, the Grand Canyon and Channeled Scablands, and more.

Soil may be the most important geologic resource on the planet. Discover how geologists classify soils, focusing on the concept of soil horizons, which are distinct layers that often vary in composition, color, and texture. Analyze how this cross section, which signals soil fertility, differs depending on the type of biome. Learn how soils form and how easily they are destroyed by erosion.

Rivers are the key to understanding why many landscapes look the way they do. Study how rivers form, how they sculpt the land, how water and sediment move in a river, and how rivers change course over time. Rivers also create habitats for plants and animals, both of which influence the landscape. Finally, signs of vanished rivers tell the story of geologic events in the deep past.
