Today, people are “mapping our world” with the aid of Geographic Information Systems (GIS) technology. Mapping can be done in the field or the lab—even from smartphones. You can make maps with real-time data about wildfires, tsunamis, and tornadoes. You can make maps with imagery collected with visible light, infrared, and radar data.
A map can represent data from an area on a flat surface. The part of our Earth system most frequently mapped is the atmosphere. Weather—the state of the atmosphere at a particular place and time—needs constant monitoring because it perpetually changes as weather systems evolve and move.
Awareness of what the weather is and is likely to be has numerous benefits. Weather can be hazardous, causing injuries, death, and loss of property. Weather maps are valuable analytical tools for informing people about current or future conditions.
This activity uses “flubber” to demonstrate the visco-elastic properties of the Earth’s lithosphere and shows isostatic rebound in action.
The key properties of soil (physical, biological, and chemical) determine recreation, crop production, range, water/erosion conservation, forestry, and engineering uses of the soil. Soil surveys help us understand how soils differ and how they behave under various land management systems. The heart of a soil survey is the soil map showing the spatial distribution and variability of soils on the landscape.
Geoscientists use special boats to conduct research at sea. One of these boats is named the JOIDES Resolution (JR). Unlike most oceangoing vessels, the JR has a flat bottom, a 6.4-meter hole in the middle, 12 laboratories, and a derrick towering 67 meters above the waterline! Why? So scientists can sail nearly anywhere in the world to drill for samples of rocks and sediment from below the seafloor. What for? In hopes of discovering clues about Earth's history and structure, life in the deep biosphere, past climate change, earthquakes and natural resources.
The USGS has been studying glaciers in Glacier National Park since 1850. It is estimated that there were 150 glaciers in the park back then, and when the national park was established in 1910. Today only 25 glaciers remain.
Scientists go back every year to repeat photographs, as well as to examine the ice and the ecology of the landscape to see how glacial retreat is affecting plant and animal species that live there.
This investigation will help you to learn that different geologic materials have different characteristics.
People must mine minerals to provide all kinds of materials that we depend on in our lives. The purpose of this activity is to test the conductivity of various minerals with a simple electrical circuit and draw conclusions about which ones would be used in electronics.
Learn the characteristics of difference kinds of minerals in this hands on investigative activity.
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.
