CH2 RH2 Questions What is Rayleigh scattering and how does it makes the sky blue? What does position of the Sun have to do with it? 1. 2. What is the thermal equator and how does it shift? 2773. How does Refraction operate? 4. How do these terms relate: Reflection & Albedo? 5. What happens when Evaporation takes place? 6. What is the difference between the Marine effect (or maritime effect) and Continentality? How is Specific Heat involved? 7. How are the Gulf Stream and the Kuroshio (Japan Current) similar? What is an urban heat island and what are their causes? How can cities reduce the urban heat island effect? 8.Explanation / Answer
1.In rayleigh scattering the scattering is inversely proportional to wavelength.so lesser the wavelength greater will be scattering.Hence as blue lights have less wavelength sky is blue.The blue light will be more deep in color when sun remains overhead and changes to fade blue as sun comes to horizon .
2.It is a circle covering all the locations having highest mean annual temperature in every longitude around the globe.It shifts more north ward from geographic equator because northern part has more land area and hence more strongly heated.
3.Refraction occur when there is changes in medium takes place in terms of density hence it leads to bend in the path of light.
4.albedo is a form of energy which measures the percentage of light reflected from the incident total light In the form of diffusive reflection where as reflection is the property of the material which measures the ratio of reflected to total incident light.
