Abstract: The quiet regions of the solar surface are densely populated with small and weak magnetic flux patches. These patches contain an amount of magnetic flux comparable to what is found in active regions during the peak of the solar cycle. This suggests that these small-scale magnetic fields are essential components of solar magnetism and may play a critical role in the transport of mass and energy through the solar atmosphere. The magnetic flux of the quiet Sun (QS) is divided between network and internetwork features. Internetwork fields are found within the interiors of supergranular cells, while network fields outline the boundaries of these supergranules. Together, they create a dynamic environment where magnetic fields frequently emerge, move, and interact with one another. The spatiotemporal evolution of the QS magnetic fields is coupled to convective motions, leading to various processes that may contribute to chromospheric heating. These processes include, among others, the formation of vortices, the emergence and reconnection of magnetic field lines, and the generation of magnetohydrodynamic waves. In this talk, I will review our current results and understanding of QS magnetic activity and how it impacts the energetics and dynamics of the quiet solar atmosphere.
