"Telluric" refers to anything related to the Earth, particularly in terms of its physical properties and processes. The term is often used in geology and geophysics to describe phenomena that originate from or are influenced by the Earth's structure and materials. For example, telluric currents are natural electric currents that flow through the Earth, often associated with geological formations. In a broader context, "telluric" can also relate to the Earth's environment and its interactions with other celestial bodies. This includes the study of how solar activity affects the Earth's atmosphere and magnetic field. Understanding telluric phenomena is essential for fields like geology, environmental science, and geophysics.
