Editing Inversion (meteorology) (section)

==Normal atmospheric conditions==
Usually, within the lower atmosphere (the [[troposphere]]) the air near the surface of the [[Earth]] is warmer than the air above it, largely because the atmosphere is heated from below as solar radiation warms the Earth's surface, which in turn then warms the layer of the atmosphere directly above it, e.g., by [[thermal]]s ([[Convection (heat transfer)|convective heat transfer]]).<ref>Nagle, Garrett, and Paul Guinness. Cambridge International A and AS Level Geography. Hodder Education, 2011. 41.
