Students will become familiar with fire terminology, realize how fire can be used as a management tool, and better understand the factors that need to be considered when planning a prescribed burn. In this activity the students will form opinions around fire management issues. They will then work in...

Scientists, engineers, and others create geologic maps to determine the best places for people to settle, build, farm, and use land in a variety of ways. They also use geologic maps to monitor the ways that human activity might be changing the land itself over time. As the Geologic Map of Karst in...

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 volcano is a vent in the surface of the Earth through which magma and gasses erupt. Volcanic eruptions are among the Earth's most powerful and destructive forces, but volcanoes are also creative. Volcanoes have also shaped the Earth's landscape, as many of our mountains, islands, and plains 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.

"There are many glaciers all over Alaska. Flying into Lake Clark National Park and Preserve through Lake Clark Pass, you will see many glaciers. These glaciers were growing during the last Ice Age. Now many are retreating because Alaska is getting warmer. As the glaciers melt they leave behind...

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...

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,...

Sinkholes are natural depressions in the land caused when limestone and soils dissolve. They form when groundwater removes rock underground. They can form by slow gradual sinking or by sudden collapse of an underlying hole. Sinkholes are common in about one quarter of the U.S. You can usually...

An earthquake occurs when massive rock layers slide past each other. This motion makes enormous vibrations, which travel from the site of the earthquake in waves. The waves (seismic waves) travel all the way through the Earth. Seismologists can record these waves when they reach Earth's surface...
