How could a rock formed by volcanic activity get to this shoreline, surrounded by sedimentary rocks? That was the question a group of third-grade students asked--and answered--during an inquiry-based summer camp. Over a two week timeframe, the students practiced basic inquiry skills such as observing; measuring; describing and drawing; sharing…

Imagine recreating a tsunami's force in a bathtub or exploring the potential of geothermal energy by using steam from a kettle to illuminate a light bulb. These types of activities and more are offered in Matthew Levy and Mario Salvadori's collection of experiments and demonstrations in Earthquakes, Volcanoes and Tsunamis. More than 30 easy and…

The most common igneous minerals and their diagnostic properties, which the author considers the most significant and pragmatic aspect of igneous geology for physical geography students, are discussed. The nature of igneous geology is also examined. (RM)

This paper explores the uses of true landform miniatures and small-scale analogues and suggests ways to teach geomorphological concepts using small-scale relief features as illustrative examples. (JDH)

Within this huge national park (over two million acres spread across Wyoming, Montana, and Idaho) are steaming geysers, hot springs, bubbling mudpots, and fumaroles, or steam vents. Drives on the main roads of Yellowstone take tourists through the major hot attractions, which also include Norris Geyser Basin, Upper and Lower Geyser Basin, West…

One of a series of general interest publications on science topics, the booklet provides those interested in the study of caves (speleology) with a nontechnical introduction to the subject. Separate sections examine types of caves, how caves form, cave features, minerals found in caves, uses of caves, and caves as natural underground laboratories.…

Reports statistics on the type and amount of geologic mapping in the U.S. during 1976. (MLH)

Provides written tour of Colorado Rockies along San Juan Skyway in which the geological features and formation of the mountain range is explored. Discusses evidence of geologic forces and products such as plate tectonic movement and the Ancestral Rockies; subduction and the Laramide Orogeny; volcanism and calderas; erosion, faulting, land…

Discusses environmental pollution problems caused by direct discharge of submarine seeps of marine oil. (PEB)

Discusses characteristics of sand, its derivation, various colors, shape, grain size, how it is transported, how sand dunes are formed, and economic uses. (BR)

Seismological research last year was directed toward several fundamental problems. Advances were made in the computation of theoretical seismograms for complex structures and sources. (BB)

Introduces a series of related articles on the study of ocean/continent boundaries (margins) within the framework of plate tectonics. Topics discussed include: early attempts to interpret ocean/continent boundaries, Atlantic-type margins, Pacific-type margins, the edges of ancient oceans, and future challenges in the study of continental margins.…

The development of the South Atlantic continental margins through geological time is discussed in a series of three time slices, all of which depict various characteristics in the initial formation of this margin during the Cretaceous period (180 to 65 million years ago) of the Mesozoic era. (BT)

One of a series of general interest publications on science topics, the booklet provides those interested in landforms of the United States with a nontechnical introduction to the subject. Separate sections examine deposital versus erosional landforms in the central stable region of the United States, the Appalachian Highlands, the Ozark Region,…
