One common misconception is that Creative Commons (or CC) licenses replace copyright. CC is just a modifcation of copyright. Copyright means that all rights are reserved. CC licenses allow you to decide which rights are reserved, enabling you to share your work more broadly without giving up full control of how your work is used.
Because these licenses allow users to freely distribute, and sometimes to remix or reformat, they are very popular for open educational resources.
No. For something to be considered a true OER it has to comply with the 5 Rs*. It can be Reused, Retained, Redistributed, Revised, and Remixed. Some licenses and some license combinations prevent items from being redistributed, revised, or remixed, and thus items published under these licenses are not considered true OERs. Although there is debate about which licenses are too restrictive, NonDerivative, NonCommercial, and ShareAlike licenses can all in different circumstances limit users abilities to openly and freely reuse a work. That doesn't mean you can never use items under these licenses. Learn how on the Creative Commons Remixes page.

*The 5Rs are an adaptation of "Defining the 'Open' in Open Content and Open Educational Resources, originally written by David Wiley and published under CC BY 4.0.
Two terms you have probably heard in association with Creative Commons or with copyright are Public Domain and Fair Use.
Public Domain refers to items on which the copyright has expired, like the "Happy Birthday" song or the works of Shakespeare. Currently in the U.S., an item enters the public domain 70 years after the creator's death. Creators can also choose to release their works to the public domain upon creation by applying the CC0 license.
Fair use refers to the use of copyrighted materials that is considered to not be a violation of copyright. Copyright law lays out certain situations and use cases that would qualify as fair use for purposes like education, scholarship, and research. University of Minnesota has developed a tool to help you think through whether a particular situation is fair use, you can use the tool Thinking Through Fair Use here (please note that this form is not legal advice). You can also inquire with the library's copyright expert, Federico Martinez-Garcia, listed on this page.
Another license you may come across in looking for open content is GNU-FDL, or GNU Free Documentation License. Although this license is typically associated with open software documentation, it can be used for any open text. This license requires that future adaptations or reproductions include: attribution; documentation of any changes; any derivative works must be licensed under the same terms; invariant sections (as defined by the author), the warranty, the full text of the license, and any warranty disclaimers must be included unchanged; and technical measures must not be used to control or obstruct future editing or distribution. To learn more view the GNU-FDL site.
GNU-FDL is not wholly compatible with CC licenses at present. Although you could redistribute a CC-BY or a CC-BY-NC item under a GNU-FDL license, SA (share alike) and ND (non-derivative) licenses are not compatible with GNU-FDL. For more on compatibility, visit the GNU License Compatibility Page.

You may already know which license you'd like to apply to your work, but it's important that you apply it the right way. Although it appears that all you need to do is add some letters or a logo, it's important that you get the license from the Creative Commons site.
Each license has three layers. One is obvious, it's the "human readable" layer, this is the logo you see and the rights you understand from the license. Beyond this layer, each license also has a legal layer, the legal code for lawyers and courts to use in cases of dispute about CC licensed works. Finally each license also posesses a machine readable layer. This is what allows tools like Google to discover your work when people search for items with a CC license.
To pick and acquire your CC license with all three layers, visit the Creative Commons Share Your Work page and use the Choose a License workflow.
