      I’m not suite sure what you mean here, it is a term used to mean different thingsisn different areas. In Geology, extension is a term used to descibe when a tectonic plate is being stretched, this causes it to get thinner, and eventually a new ocean could form.

      Extension or extinction?

      Extinction means ‘reduce to zero’. In Biology, this might mean when all animals of a species have died out, that species becomes extinct, or when a virus is ‘wiped out’, it becomes extinct. In physics, when there is absolute darkness, where no light exists (at all), then light is said to be extinct.

      Now ‘extension’ can mean a number of things, including to add to, increase, lengthen – you could almost say it’s kind of the opposite of extinction!!

      I struggle with this as a question because I don’t understand it. I don’t know of any process called ‘extension’ but I see Kate knows one. Then I though may be this is a typo (a mistake in typing) and Rob has answered that. To be a scientist you need to ‘Be Curious and Ask Why’ if that does not answer your question ‘Ask Why’ followed by ‘Really’. So if these answers do not answer your question ask it again, may be using different words.

      As Kate said, “Extension” is used to mean so many different things.

      I’m going to start with the basic idea.
      If you can find an elastic band, put a pin through a piece of paper and put the elastic band on the paper, with a part of it touching the pin. Draw around the band (without any stretch).
      Next up, stretch that band (use your non-writing hand) and draw where it gets to.
      Remove the band, the extension is the difference between the unstretched band and the stretched band.

      Language is a complex thing, we often use words that come from one meaning and use them for something else. So “extension” then could be what something looks like if we take what we know and stretch that.
