View Resource Tectonic Plates, Earthquakes, and Volcanoes

According to theory of plate tectonics, Earth is an active planet -- its surface is composed of many individual plates that move and interact, constantly changing and reshaping Earth's outer layer. Volcanoes and earthquakes both result from the movement of tectonic plates. This interactive feature shows the relationship between earthquakes and volcanoes and the boundaries of tectonic plates. By...

View Resource Total Solar Eclipse Animation

Solar eclipses result from the alignment of the Sun, Moon, and Earth. Total solar eclipses, in which the Sun is completely blocked by the Moon, are a spectacular and rare sight to witness. This animation, adapted from a NOVA television broadcast, shows a simulated total eclipse and explains some of the features that can be seen. The clip is one minute thirteen seconds in length.

View Resource Mount St. Helens: Before and After

When Mount St. Helens erupted on May 18, 1980, the top 400 meters (1,300 feet) of the volcano disappeared in a blast that covered more than 390 square kilometers (150 square miles) and sent thousands of tons of ash into the upper atmosphere. This collection of still images and video depict before-and-after scenes of Mount St. Helens and its surroundings, allowing viewers to witness the results of...

View Resource Plate Tectonics: An Introduction

In the early 1900s, most geologists thought that Earth's appearance, including the arrangement of the continents, had changed little since its formation. This video segment describes the impact the theory of plate tectonics has had on our understanding of Earth's geological history, and provides a brief overview of what is currently known about the Earth's tectonic plates and their motions. The...

View Resource Organic Farming: Conserving Top Soil

Fueled by economic pressure to maximize crop yields and government incentives to produce only one type of crop, contemporary American farmers have been facing a crisis reminiscent of one that hit the Great Plains in the 1930s. This video segment explains why more and more farmers are opting for sustainable, organic farming practices to help preserve the valuable topsoil that they rely on for...
