Subject Science  Class=10 Unit= 24 Topic=Atmosphere Topic: Teaching Greenhouse Effect Objective:           At the end of the lesson teacher will be able in the following: →→To define greenhouse effect →→To understand about globalization →→Effect of globalization →→Preventive measures                   Introduction of Greenhouse Effect: The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases. Solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface, which ...
