  In the following short review we will outline some of the possible
interaction processes of lower solar atmospheric plasma with the embedded
small-scale solar magnetic fields. After introducing the topic, important types
of small-scale solar magnetic field elements are outlined to then focus on
their creation and evolution, and finally end up describing foremost processes
these magnetic fields are involved in, such as the reconnection of magnetic
field lines and the creation of magneto-hydrodynamic waves. The occurrence and
global coverage in the solar atmosphere of such small-scale phenomena surpass
on average those of the more explosive and intense events, mainly related to
solar active regions, and therefore their key role as building blocks of solar
activity even during the weaker phases of the 11-year solar cycle. In
particular, understanding the finest ingredients of solar activity from the
lower to the upper solar atmosphere could be determinant to fully understand
the heating of the solar corona, which stands out as one of the most intriguing
problems in astrophysics nowadays.
