PPT-15.3 Layers of the atmosphere

153 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. Students m ust read the background material plot data points and determine where layers begin and end from their comprehension of the reading material Grade Level 10 Time Required 35 45 minutes Materials No additional materials are needed Backgroun 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. Earth’s Atmosphere. Contains the oxygen needed for life. Filters out much of the ultra violet radiation emitted from the Sun. . Holds surface heat to the Earth . Allows for weather (wind, rain) and water cycles. 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.. Layers of the Atmosphere Mania Game1. What is unique about the troposphere?2. The coldest temperatures occur at what altitude?3. Temperature increases in what two layers?4. Temperatures decrease in wh NC Essential Standard:. Compare the composition, properties, and structure of Earth’s atmosphere to include: mixtures of gases and differences in temperatures and pressure within layers.. There are . and the Impact on Living Things. Earth’s Atmosphere. The gases that surround Earth (and other planets) make up the atmosphere. These gases are like an envelope that protects us from the radiation that is caused by the sun’s . By Hero Kim.

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.. . . of .
