We identify the scientific prospects for studying low-energy cosmic rays, the interstellar medium, and the associated gamma-ray emissions with a next-generation wide-field telescope from 200 keV to ~10 GeV. With improved angular resolution and more than an order of magnitude better sensitivity than previous instruments, the All-sky Medium Energy Gamma-ray Observatory (AMEGO) would allow for the first time to study in detail the low-energy cosmic rays, which play a fundamental role in the formation of stars and in the dynamics of the interstellar medium. It would allow mapping the cosmic-ray distribution in order to understand their propagation in the Galaxy.
We discuss the importance of having such a telescope, and we present the predictions for the gamma-ray continuum both at large scale and in individual clouds, and for de-excitation nuclear lines.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
