There are two terms that keep coming up as I research out MODx, they are Chunks and Snippets. Below I am going to do my best to describe what the function of both is inside the MODx environment for the sake of journaling my learning as I go along,
MODx Chunks
These are pieces of non-functional html (non scripted) that can be dropped into the content area of a html page. An example of how a chunk could be used in my opinion would be something like this that would simply be hyperlinked to a form page. This is something that you would probably want to have at the bottom of multiple pages in your website..

The main function of the chunks in my opinion (and I may be off base with this a little bit as I am just learning the whole thing) is to save the end-user, or editor in this case, a lot of typing. Another practical use for the "Chunks" feature would be if certain pages of a site had a few lines that served as a disclaimer of sorts. Chunks would work well for this in my opinion.
MODx Snippets
Now, let’s say you have a piece of dynamic code that you want to introduce onto multiple pages of your website like a search box (an example of an ajax search box can be found here: http://www.heber-springs.com/content/). You can use the snippets feature to add these types of dynamic drop-ins.
In my explorations I have also seen where Snippets are also used to call in things like menus as well.
