I use this page to list the videos and photos mostly of geological interest I bookmarked on Twitter. This page is intended to be an open and searchable archive of those entries. I do believe one good photo/video worths more than ten thousand words, especially when introducing natural processes to students. Twitter has troves of those material openly shared by users around the world. To use the material externally, I do recommend contacting the original author for permission.
