Leading Countries in the Production of Rare Earth Elements
Geology.com

This chart shows China's dominance in the production of rare earth elements between 1994 and 2022. The United States was a significant producer through the 1990s, but low-priced materials sold by China forced mines in the United States and other countries out of operation. As China limited exports, and prices increased rapidly in 2009 and 2010, mines in Australia and the United States became active again. In 2018, data from Burma / Myanmar became available, causing an increase in production that may have been present but unreported prior to 2018. Graph by Geology.com using data from the United States Geological Survey.

Water Levels to Be Measured in 1,400 Southern Idaho Wells
United States Geological Survey

Image: USGS hydrologic technician collects a groundwater-level measurement from an aquifer monitoring well at the Idaho National Laboratory. Public domain image by USGS.
Between April 3 and 14, USGS employees, working with the Idaho Department of Water Resources and the Bureau of Reclamation, will measure groundwater levels in more than 1,400 private and public wells that draw from the eastern Snake River Plain aquifer.
The data collected from this large-scale measurement will help water managers understand the status of the aquifer as the state enters the April-September irrigation season. In addition, the IDWR will use the data to continue improving their computer model of the aquifer.

Last year, the U.S. produced 4,090 million megawatthours of electric power. Generation from renewable sources -- wind, solar, hydro, biomass, and geothermal -- surpassed coal-fired generation for the first time. Renewable generation surpassed nuclear generation for the first time in 2021 and continued to provide more electricity than nuclear generation last year. Graph and caption by EIA.

Is "The Great Unconformity" a Misnomer?
Speaking of Geoscience - The Geological Society of America's Guest Blog
Speaking of Geoscience - The Geological Society of America's Guest Blog
What Is a Misnomer?
Geology.com

Misnomers are "incorrect names". Examples include "Herkimer diamonds" and "green amethyst". Herkimer diamonds are doubly-terminated crystals of quartz but the name "diamond" has been attached to them for a novelty purpose. Green amethyst is a name used for transparent specimens of green quartz that are often faceted and sold as "green amethyst". That name is incorrect because the definition of amethyst is a purple variety of quartz.
Using an incorrect name when an item is being offered for sale can be misleading and result in civil and/or criminal liability. The Federal Trade commission recently targeted "green amethyst" and "yellow emerald" as names that can be deceptive or misleading. A quote from the FTC: "It is unfair or deceptive to mark or describe an industry product with the incorrect varietal name."
