Specific things by name
Science Topics provides links to USGS scientific information by categories, which are types of things. We have seen that occasionally people are looking for some specific thing by its name instead. In most cases these things would be described in several different categories, so this page provides a way to find the corresponding categories.
Arctic National Wildlife Refuge, an area of Federal land located on the North Slope of Alaska east and south of Prudhoe Bay. Exploitation of petroleum resources in this area is a political controversy.

General concept of the recycling of material in the earth's crust, from the formation of mountains and the transfer of their material through erosion to the oceans as sediment, to its reincorporation in new mountains through tectonic subduction.
