1. A person who believes in the Earth's internal structure and geological processes: This is the most likely interpretation, as it's a direct connection to the word "geo" which refers to the Earth. Someone who studies geology or geophysics could be considered a "geoist" in this sense.
2. A person who advocates for "geoism": This assumes a political or philosophical ideology called "geoism" exists. While there are no formal political movements or ideologies named "geoism," it could be a potential term for a hypothetical movement focused on:
* Geoengineering: Manipulating Earth's systems to combat climate change.
* Geopolitics: Examining the influence of geography on international relations.
* Geocentrism: The belief that the Earth is the center of the universe (though this is not scientifically supported).
3. A person who is "geo-centric" in their thinking: This could imply someone who prioritizes local or regional concerns over global issues, or focuses heavily on physical geography and its impact on society.
Without further context, it's impossible to definitively determine the meaning of "geoist".
If you encountered this term, it's best to look for more information about its context or ask the person who used it for clarification.
