Exploring Energy with GIS Activity Source: ESRI. Adapted with permission. Locating crucial energy resources involves examining phenomena under, on, and above Earth’s surface. Some of these phenomena change frequently, such as winds. Others, such as oil and coal deposits, are products of long series of geologic processes. Yet all are geographic in nature — they occur in specific places for specific reasons. To determine the best regions to explore for new natural gas deposits, to determine the ideal places for wind farms, or to locate the best rooftops for solar panels in a city, Geographic Information System (GIS) technology and methods are vital.

Exploring for Petroleum - Modeling an Oil Reserve Activity Source: Adapted from “Earth System Science in the Community,” American Geosciences Institute, 2005 Background Since 1970, oil and natural gas have provided more than half of the energy used each year in the United States to produce electricity, heat, transportation fuels, and many everyday products from balloons to vitamins. Oil and natural gas are forms of petroleum, a word that literally means “oily rock. [Read More]

Exploring Geoheritage From Space Activity Source: Adapted with permission by NASA. Great images of geoheritage sites can be found everywhere. But no one holding a camera on Earth can “back away” far enough to get the extraordinary perspective captured by NASA satellites. In celebration of Earth Science Week 2016, NASA’s Earth Observatory has created a special collection of images and articles showcasing geoheritage sites in America’s National Parks. Two such sites are Yellowstone National Park (Wyoming/Montana/Idaho) and Hot Springs National Park (Arkansas). [Read More]

Exploring Geoheritage Through EarthCaching Activity Source: Adapted with permission by Geological Society of America. An EarthCache is a special site that people can visit to learn about a unique geoscience feature or aspect of our Earth. Visitors to EarthCache sites can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth. EarthCaches are part of the greater global adventure game of Geocaching. [Read More]

Exploring Permafrost in the Arctic Activity Source: Written by AGI with the Natural Resources Conservation Service Permafrost, frozen ground lasting at least two years, is found in Earth’s coldest regions: the Arctic, boreal zones, Antarctica, and high-altitude areas. It profoundly impacts the plant, animal, and human communities in these regions. Permafrost underlies 15% of the northern hemisphere’s exposed land. It is prevalent across the Arctic and extends into areas like Alaska, Canada, Greenland, Russia, and the Tibetan Plateau. [Read More]

Exploring Porosity Activity Source: The NEED Project. Adapted with permission. Earth scientists play a vital role in harvesting the energy resources on which we all rely. When preparing to drill for oil, for example, geoscientists must assess many aspects of a rock stratum (layer). For example, they must figure out the volume of the rock’s pores, or empty spaces, as compared with the rock’s total volume. This is called the rock’s porosity. [Read More]

Exploring the Age of the Seafloor Activity Source: Written by AGI based on lessons by the International Ocean Discovery Program The Earth’s surface is made up of tectonic plates that fit together something like puzzle pieces, forming fault lines where they meet. There are seven major plates and some smaller ones. These plates move apart at divergent boundaries and collide at convergent boundaries. At transform boundaries, the plates slide past each other.

Exploring Watersheds in North America Activity Source: Written by AGI for ESW 2024 Watersheds serve as natural drainage systems, collecting rainfall and channeling it towards a common outlet such as lakes, rivers, or oceans. The health of watersheds directly impacts the availability and cleanliness of water for drinking, agriculture, and ecosystems. Additionally, watersheds play a critical role in regulating water cycles, mitigating floods, and replenishing groundwater reserves. Understanding and managing watersheds is essential for sustainable water resource management and ecosystem conservation, ensuring the well-being of both human and natural communities. [Read More]

Find Your Park Activity Source: Adapted with permission by National Park Service. A park can be many different things to many different people. For many people, Canyonlands National Park is a favorite showcase of geology. In each of the park’s districts, you can see the remarkable effects of millions of years of erosion on a landscape of sedimentary rock. The Green River has carved a channel out of rock layers deposited nearly 300 million years ago creating an open book for earth science enthusiast of all ages. [Read More]

Finding Slope Activity Source: Soil Science Society of America. H.M. Galloway, A.L. Zachery, Agronomy Department, Purdue University, Revised by S.S. Fulk-Bringman. Adapted with permission. Earth scientists play an important, if largely invisible, role in many aspects of our daily lives, such as building homes or growing food. For example, geoscientists help determine which locations would be best for undertaking these vital activities. The slope of the soil is an important soil property to consider when building or planting. [Read More]
