Atmospheric Stability

Atmospheric Stability. Why is this Important?. A stable atmosphere is associated with air pollution, fog, and strong surface temperature inversions in winter. An unstable atmosphere is associated with lots of atmospheric mixing, with good air quality and sometimes convection/thunderstorms.

Students will know how the Hydro- and Atmosphere was formed

Students will know how the Hydro- and Atmosphere was formed. Back in the beginning of the earth, it was believed our planet was entirely molten. The cooling started as heavier materials sunk to the core and lighter ones rose to the top. This allowed for stability in the planet.
