Given the nature of explosive volcanic eruptions here on Earth and the important roles of dissolved gases and plate tectonics, what might you...

Well, I would expect any planet with no plate tectonics to have little to no volcanic eruptions. If there is no mantel, then there would be no liquid rock for the planet to eject in the first place. In addition, the presence of volcanoes on a planet would suggest a mantel and possible plate tectonics.


Dissolved gasses in the magma are released as volcanoes erupt. On earth, these gasses are commonly water vapor, carbon dioxide, sulfur dioxide, sulfuric acid, and hydrogen halides like HF, HCl, and HBr. A strongly volcanic planet would have an atmosphere of similar composition; consider, for example, Venus. Venus is the most volcanic planet in the solar system, with almost 90% of the surface being basalt rock, or freshly cooled lava. The atmosphere of Venus, in comparison, is primarily carbon dioxide with trace sulfur dioxide--an almost perfect match.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
