Chapter 15 The Atmosphere
Chap 15, Sect 2 (Atmospheric Heating) Objectives: 1. Describe and show an example of conduction, convection, and radiation. 2. Explain the relationship between the greenhouse effect and global warming.
Radiation - transfer by electromagnetic waves Conduction - transfer by direct contact Convection - transfer in fluids by circulation
The Greenhouse Global Warming VS. Effect § gases (CO 2 and § an increase in water vapor) absorb average global thermal energy and temperatures radiate it back to Earth § an increase in § this process reminds greenhouse gases us of an actual in the atmosphere greenhouse
Global Warming Current research shows that 81 to 100 percent of climate scientists believe that global warming is caused by human activities. Climate 101 Interesting Debate (the views expressed in the video might be perceived as controversial – since politics is involved. This video simply represents both sides of the issue, in order to provide a global perspective for students) Effects of Climate Change
§ Energy from the sun is the driving force behind the water cycle, which contributes to create Earth’s weather. § The greenhouse effect is Earth’s natural heating process. Increasing levels of greenhouse gases could cause global warming.
