Ijust want to know what this means what does this mean i have a question and i dont get what it means "in addition to the glossary on pages 828–853, on which pages is there an additional geographic dictionary" what does that mean? ?

I’m assuming this question is in reference to a text book... In case you didn’t know, a glossary is a list of words and their definitions, usually at the end of a book or chapter. What the question is asking for is where else in the book can you find a list of words + their definitions related to Geography. To get started, you might want to check the end of each chapter.

Hope I helped (:
