Since our beginnings, we humans have had a narrow view of our home - Earth. For many years, standing on the ground and looking around or climbing a mountain and squinting down were the most useful ways people had of trying to understand the planet's surface. Only in the past few hundred years have...

A normal fault occurs when rocks break and move because they are being pulled apart. As the area is stretched, the rocks move along the fault. Each movement causes an earthquake. This model demonstrates how a block of rock is extended by a normal fault.

The JOIDES Resolution (JR) has physical dimensions unlike most oceangoing vessels. Why? So that scientists can sail nearly anywhere in the world to drill for samples of rocks and sediment from below the seafloor — in hopes of discovering clues about Earth’s history and structure, life in the...

Core samples are small portions of a formation taken from an existing well and used for geologic analysis. The sample is analyzed to determine porosity, permeability, fluid content, geologic age, and probable productivity of oil from the site. Drilling is the only way to be sure that oil and gas...

Raindrops contain more than just water. In addition to the small particles of dust around which water drops form, raindrops can contain chemicals found in the atmosphere. Often rain is slightly acidic. This “acid rain” can chemically affect (weather) materials it touches. The amount of...

Bombarded by Web sites, the evening news, newspapers, and popular magazines, citizen scientists often have to interpret scientific information directly from the media. Sometimes this can be a confusing process. How can you, as a citizen scientist, figure out whether science information you get from...

Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off. In this activity,...

Soil is often overlooked as a natural resource. Like fossil fuels, we depend on it for energy in the form of foods. And, like fossil fuels, it is nonrenewable. Soil is a delicate balance of inorganic minerals, organic matter, living organisms, soil water, and soil atmosphere. The natural development...

Elastic waves that move through the Earth are called seismic waves. Want to study them more closely? SeisMac is a free application that displays the output from the Sudden Motion Sensor in recent Mac laptops as a real-time, three-axis, acceleration graph, or, more commonly, a seismogram. Once your...

On our ever-changing Earth, conditions may change quickly or slowly. Some changes come from natural processes; some from human activity. Satellites allow us to see conditions and track changes over time — in land use, forest health, land/water interface, and so on. Since 1972, Landsat...

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...
