The JOIDES Resolution is an amazing ship that contains all the equipment necessary to drill into the ocean floor for samples of rock and sediment: a derrick, drill pipe, drilling tools, and drill bits. Once the cylindrical core sample arrives on the rig floor, the drill crew passes the 10 m core to technicians. They, in turn, carry it to the catwalk, where it is cut into 1.5 m sections and labeled. After the core is brought up on deck, the technicians notify the rest of the crew by yelling: "CORE ON DECK!"
One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible aftereffects. An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. For hundreds of millions of years, the forces of plate tectonics have shaped the Earth as the huge plates that form the Earth's surface slowly move over, under and past each other. Sometimes the movement is gradual. At other times, the plates are locked together, unable to release the accumulating energy. When the accumulated energy grows strong enough, the plates break free. If the earthquake occurs in a populated area, it may cause many deaths and injuries and extensive property damage.
Hurricanes are among the most common and most destructive types of natural hazards on Earth. Because they occur across space and time, hurricanes can be better understood using maps, particularly digital maps within a Geographic Information Systems (GIS) environment. GIS allows you to use maps as analytical tools—not maps that someone else has made—but using your own maps to make decisions.

National parks play an important role in preserving our nation's heritage for the enjoyment, education, and inspiration of current and future generations. National parks are in the “forever business.” The National Park Service is always looking forward to ensure that what it does is sustainable.
An earthquake simulation activity from IRIS.
Push away from those paper seismograms and get outside to make your own earthquake waves! You're going to learn about earthquake location kinesthetically. In the activity below, you will model how earthquake waves travel through the Earth at different speeds. You also will construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel-time curve). Finally, you'll use the constructed travel-time curves to locate the epicenter of a simulated earthquake by triangulation.
Geoscientists, energy researchers, and others in numerous careers and disciplines use GIS and its integrative nature to tackle these issues. You can, too.
