PPT-The Structure of the Atmosphere

Weather Whether the weather be fine Or whether the weather be not Whether the weather be cold Or whether the weather be hot Well whether the weather Whatever the weather Whether we like it or not. Controlled atmosphere storage refers to the constant monitoring an d adjustment of the CO and O levels within gas tight stores or containers The gas mixture will constantly change due to metabolic activity of the respiring fruits and vegetables in t 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. Radiative. Transfer Model. (CRTM). Overview . and Tutorial. Overview. Some background. How does radiation interact with matter. Development of . radiative. transfer. Additional CRTM components (not all, . • Pressure gradient controlled by ‘hydrostatic equilibrium’ — pressure supports weight of gas above it, and, because it is gas, density drops with decreasing pressure; combination of effects leads to e-folding drop in pressure over . 24.3. The Sun .  . Because the sun is made of gas, no sharp boundaries exist between its various layers. Keeping this in mind, we can divide the sun into four parts: the solar interior; the visible surface, or photosphere; and two atmospheric layers, the chromosphere and corona.. . General Characteristics. Composition- Gases, water vapour and dust particles. Structure: Layered structure, variation with altitude, latitude and seasons; Importance and characteristics of each layer.. Objectives. Describe the composition of Earth’s atmosphere.. Explain why air pressure changes with altitude.. Explain how air temperature changes with atmospheric composition.. Describe the layers of the atmosphere.. . General Characteristics. Composition- Gases, water vapour and dust particles. Structure: Layered structure, variation with altitude, latitude and seasons; Importance and characteristics of each layer.. 7.5 Composition and Structure of the Atmosphere What is the composition of Earth’s Atmosphere? SC.6.E.7.9, LA.6.2.2.3 Composition of Earth’s Atmosphere The atmosphere is the protective covering of Earth. It keeps Earth warm and protects it from Atmosphere Essential Question: How are we changing our atmosphere? Learning Goals: Be able to identify the layers of the atmosphere. Describe what molecules make up the atmosphere. Atmosphere Atmosphere 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% ).

On the basis of the characteristics of temperature and air pressure there are four distinctive layers from the earth surface upward . .
