telluric

Telluric refers to anything relating to the Earth. The term originates from the Latin word "tellus," meaning Earth. It is often used in scientific contexts to describe phenomena or measurements that are connected to our planet.

One common application of "telluric" is in the study of telluric currents. These are electrical currents that flow through the Earth's crust and mantle, and also through the oceans and the ionosphere. They are primarily generated by natural processes, such as the interaction between the solar wind and the Earth's magnetic field, or by seismic activity. Scientists study telluric currents to understand the Earth's interior, monitor space weather, and even detect earthquakes.

Another use is in the term "telluric acid," a chemical compound that is a hydrated oxide of tellurium. While named for its association with the Earth, it is a specific chemical substance rather than a general descriptor.

The concept of telluric energy or telluric force has also been explored in various metaphysical and pseudoscientific contexts, suggesting an inherent energy field emanating from the Earth that can influence human health or consciousness. However, these concepts are not supported by mainstream scientific evidence. In general scientific discourse, "telluric" strictly pertains to terrestrial origins and phenomena.
