Earth Science Stack Exchange is for questions related to earth science disciplines.

You are also welcome to ask questions about techniques or data sources related to these disciplines.
We welcome questions at different levels of expertise, but we expect that all questions are precise and answerable in the Stack Exchange Q&A format. Please look around to see if your question has been asked before. It’s also OK to ask and answer your own question.
If you are are posting an identification request, please provide as much detail as possible, with pictures, and reply to comments on your question. For rock identification requests, see the rock identification guidelines before posting your question.
If your question is not specifically on-topic for Earth Science Stack Exchange, it may be on topic for another Stack Exchange site (e.g. Physics, Chemistry). If no site currently exists that will accept your question, you may commit to or propose a new site at Area 51.
