Geo- and Atmo- must be understood as a continuous stack.
Geology and Atmosphere are processes that occur simultaneously at the scale of the particulate and the scale of the planet. This geo- is a multiplicity of interconnecting geos- geology, geography, geophysics, geopolitics, geofeminism.  Atmo- is the synthesis of all atmospheric scales: microscale, mesoscale, synoptic scale, and global scale. As apparently ephemeral as a cloud may seem , atmo- contains traces of every breath created here on Earth.
Drawing Geo- and Atmo- together requires the knitting together of multiple disciplines ; learning their strategies for collecting and analyzing evidence, and translating their data for optimal navigability. 
For our purpose, the stack becomes a section drawing, a slice of the earth.
This section is spatial, but also temporal, as it keeps the chronology of the planet.
