As of 2019-07-30, Rock identification questions are off-topic on Earth Science Stack Exchange. Please see this meta post.
Please find another forum for your question. When you do find another forum, please do refer to the underlying guide, as it is universally useful regardless of where you ask.
How to ask an "Identify this rock" question
This guide is ...
(This is just the first flash of ideas I have on that. A discussion should probably follow, and I'm 100% open to it.)
In my opinion, it is off-topic, since it is not in scope of any earth scientists to be able to discuss the CO2 trace of combustion vs hybrid vs purely electrical cars.
We can discuss how much the emissions from car traffic influence the ...
Any answer that points to just some other page, is effectively not an answer. If the answer doesn't stand on its own merit, in the absence of the information at the other end of the link, then it's not an answer. We're trying to build a body of expert content here, not just a collection of signposts.
That means you've got several options. Please, as part of ...
I think this has been addressed thoroughly in Is cross-posting a question on multiple Stack Exchange sites permitted if the question is on-topic for each site?
Personally, I would like the question closed so that the questioner decides carefully what the best site is.
Part of the issue is you are asking many questions. From your post I see:
Has planetary science contributed in any substantial way to Earth science?
Is it expected to do so as planetary exploration develops in the next few decades?
Do climate scientists know about the atmospheres of Mars and Venus and Titan and the gas giants?
They should be good questions.
The copyright should be compatible with CC BY-SA 3.0 and you need to respect any other requirements stated by the source. The answer may be yours, but the question is not.
Some why questions are acceptable. For example,
Why is the Earth an oblate spheroid?
Why does the Earth have an iron-nickel core?
These questions aren't asking the purpose of an oblate spheroid shape or of an iron-nickel core. "Why" in these contexts is just shorthand for a "what" kind of question, but where the "what" requires a lot more words:
Not a dupe, but I think the question on homework questions is relevant.
I have absolutely no problem with a student asking a clear, well-defined, on-topic question.
I don't know that the example given (the precipitation analysis) is a homework question, but I think a lot of the same issues apply - it was a very broad, poorly defined question (although ...
Describe and photograph a fresh surface.
Breaking open a rock to see an unweathered surface is very important for identification. In some cases the minerals show up better on a weathered surface so include both pictures if possible.
This isn't as important for mineral crystal specimens and we understand if you are reluctant to destroy your sample but not ...
A streak test is another test that can be useful in mineral identification. If you are able to perform this test, include the results in the question.
Streak is the colour of the powdered mineral. In many cases it is the same colour as the rock but in some it is very different from the normal surface.
To perform a streak test, you need a piece of hard, ...
I think questions on rock cutting and gem cutting for artistic or industrial purposes is off topic for Earth Science stack exchange. Some aspects may be on-topic, such as scientific aspects of rock formation and how this affects hardness and other properties relevant for artists. But there is currently no Stack Exchange site where the artistic or ...
I would say that at least 90% of questions in the whole SE can be answered by a google search - with a significantly different degree of effort, of course. And yet, that is not a reason for not having them on the network. The value added of SE, imo, is to transform information into a Q&A style. But not all information. The key criteria to me is this: is ...
I'll repost my comment as an answer to get the ball rolling, perhaps others will have some feedback as well.
In this case are you describing a situation where you have a question and you've found some explanation but the source is not official or too brief? If so, then I think that question might be well received. If you have done some independent ...
There's a practical difficulty beside the broken-window one - which is that there are (relatively) many people who can review close and re-open votes, but few who have the expertise to know whether a rock-id question is answerable.
I think that in principle if it can be answered, then it shouldn't be closed as having insufficient info - but that does mean ...
I don't think we should encourage questions that ask "what is the purpose of ..."
I don't however believe we should have a blanket ban on questions that ask "why", because the meaning of "why" in my opinion is contextual. Depending on the context, the word "why" can mean "what is the cause of?" as opposed to "what is the purpose of?". The exact ...
I don't think you can do this directly from the site. In the search bar you can search for views:500 and get all questions with at least that many views.
If you really want all the questions, sorted by views, try this query in the data explorer:
See also: Can we have a sort by view count?
It is too broad because it would take an entire book to answer the question, because the importance of planetary science for Earth Science can be addressed from many different perspectives. There could be easily over 100 different answers to that question. On Stack Exchange, we want questions that can be answered in a considerable shorter space.
You can ...
I would suggest holding off on closing for a day or two so an answer can be posted. I also think most people asking the questions would be happy with an answer that essentially says, "it is probably..."
I agree with with what's proposed in the question both for the reason mentioned in a comment:
...there should be no need to go to another site to read the question.
and because what happens in one site can't be controlled on another site, and there's not even a notification process; if the other post is altered or deleted this is not communicated back here ...
Let me answer this from the perspective of a Worldbuilding user.
One of the good things about the site is that scientific and mathematical answers are welcome (to questions tagged science-based or reality-check). I take full advantage of this, and to my knowledge, I've used LaTeX much more in my answers than anyone else there.
We do have a decent amount of ...
