MESOSPHERE THERMOSPHERE STRATOSPHERE TROPOSPHERE 12 km I am the layer of the atmosphere second closest to the ground MESOSPHERE THERMOSPHERE TROPOSPHERE STRATOSPHERE 12 km 50 km I am the layer of the atmosphere third closest to the ground. 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. Oscillating . electric and magnetic fields. propagate through space. Virtually . all energy exchange between the Earth and the rest of the Universe. is by electromagnetic radiation. Most of . what we perceive as temperature. Lesson Objectives. Describe how the temperature of the atmosphere changes with altitude.. Outline the properties of the troposphere.. Explain the role of the ozone layer in the stratosphere.. Describe conditions in the mesosphere.. Definition of the Atmosphere. . The layer of gases surrounding Earth; composed mainly of 78% nitrogen and 21% oxygen, and other gases (water vapor, dust, pollutants, etc.). Brainpop: . Earth’s atmosphere. 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.. 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.. GLY 4241 - Lecture 6 . Fall, . 2016. 2. Earth. Even in a high resolution image from space, the atmosphere is not visible. 3. Radiation. NASA graphic. 4. Chinese Smog. Haze over China. Increased desertification has added dust to China’s 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 15.3 Layers of the atmosphere Key concepts: What are the four main layers of the atmosphere? What are the characteristics of each layer? Key term: Troposphere, stratosphere, mesosphere, thermosphere, ionosphere, exosphere ). Presented By. Dr. . Banashree. . Saikia. Assistant Professor. Department of Geography. JN College,. . Boko. Structure of the Atmosphere . On the basis of the characteristics of temperature and air pressure there are four distinctive layers from the earth surface upward . Layers of the earth’s Atmosphere. Presented by-. Dinabandhu Patra. Department of Geography. Kharagpur College. Introduction:. The atmosphere can be divided conveniently into a number of rather well-marked horizontal layers, mainly on the basis of temperature. Scientist are understood and makes idea from the various sources like balloons, radio wave investigations, and, more recently, from rocket flights, radar wind-sounding, satellite sounding systems etc.. . .
