PPT-The Atmosphere

AP Environmental Science Mr Grant Lesson 45 Objectives Define the terms weather and climate Describe the composition structure and function of Earths atmosphere Relate weather and climate to atmospheric conditions. 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. Essential Points. Heat, Temperature and Temperature Scales. The Electromagnetic Spectrum. Composition of the Atmosphere. Layers in the atmosphere are defined by temperature profiles. How pressure varies in the atmosphere. CHAPTER. Charging Toward Cleaner Air in London. More than 4000 people in London died during a “killer smog” event in 1952.. In 2003, London started charging a fee to people who drove into the city during the week.. The ocean/layer of gas that surrounds the Earth. It is composed of 78% Nitrogen and 21% Oxygen. The other 1 % is a mixture of other gasses. We depend on this balance of gas for our survival. When it is out of balance, we have problems.. And its effects on our planet Earth. What is the Atmosphere. ?. The . envelope of gases surrounding the earth or another planet. ..

Radiation passes through atmosphere unimpeded.. Shortwave and longwave “windows” . 2. absorption. Energy is transferred to absorber; absorber emits energy. How does the atmosphere support life?. The atmosphere allows us to breathe. Many different types of organisms need oxygen to perform life processes. Plants require carbon dioxide to undergo photosynthesis. .
