Grand Canyon National Park Geology Tour is a narrated photographic tour of the South Rim of the Grand Canyon with an emphasis on the geology. Learn why the rocks display those magnificent colors, find out how the interesting pinnacles and buttes formed, study the different rock layers and their ages, and more.
Earthquake Finder displays recent earthquakes on a 3D (or 2D) map of the world. Recent earthquake data is obtained from a USGS data feed and is updated every 5 minutes (requires an internet connection).
Puzzling Plates inspires you to explore the large, tectonic plates that make up the surface of Earth. It includes three levels and scoring when exploring the topics of plate tectonics, maps, world geography, types of plates and plate boundaries, Earth's layered structure, motion at plate boundaries, causes of earthquakes and volcanoes.
Folds and Faults provides an illustrated overview of two significant topics in geology: folds and faults. Understanding folds and faults helps to explain how mountains form, how layers of rock change shape over time, and the underlying cause of earthquakes.
This app displays the Geologic Time Scale that represents the timeline for Earth's history and also includes illustrations and information for significant events that have occurred during Earth's long history. The Geologic Time Scale shows the names of the eons, eras, periods, epochs, and ages along with their corresponding dates.
Focus on Earthquakes provides a comprehensive description of the causes and consequences of earthquakes. The EARTHQUAKE TRACKER feature provides a visual display of recent earthquake activity.
Arches National Park Geology Tour provides an illustrated and narrated introduction to the geology of Arches National Park. Illustrations, animations, and photos by Dennis Tasa are narrated by geologist Deborah Ragland, Ph.D. of the University of New Mexico, Taos.
Need to find out when dinosaurs ruled the world or when reptiles first appeared? This is a complete reference for students, educators, professional geologists, or anyone interested in geology. This is an easy, quick way to get the names and numerical dates of each of the eons, eras, periods, epochs, and ages.
The pangaea app dynamically shows the breakup of the supercontinent Pangaea and the positions of the continents over the last 200 million years. Significant events are indicated by position (longitude) and time (millions of years ago). Several events have additional information available by touching an "info" button.
