75 Composition and Structure of the Atmosphere What is the composition of Earths Atmosphere SC6E79 LA6223 Composition of Earths Atmosphere The atmosphere is the protective covering of Earth It keeps Earth warm and protects it from. Key Terms. Atmosphere. – a thin envelope of gases that encircles the earth and other particles (aerosols). Weather. – the state of the atmosphere at a specific place and time. Meteorology. – the study of the atmosphere and the processes that cause weather. A Reynolds’ Production 2010. Review Really Fast.

Air”. is all around us and it behaves often like a liquid- it . flows, moves, and causes things to happen (weather!). . ATMOSPHERE Composition of the Atmosphere The atmosphere is comprised of a variety of gases: Major Constituents (99%): Nitrogen (N): 78% Oxygen (O 2 ): 21% Trace Constituents: Other: 1% (they are trivially simple, but they do give some interesting results if you ask the right questions). The Physical Principal – . Conservation of Mass. Bulk Silicate Earth .
