GEO 2200 / Sec 6497 Instructor: Carlos M. Canas Spring 2012 ̃ TEST 1 Review Guide 1. What is Physical Geography? Physical geography covers the topics relating to the surface of the earth - the landforms, glaciers, rivers, climate, oceans, earth-sun interaction, hazards, and more. 2. What are the four principal systems that make up the earth’s environment? Hydrosphere, atmosphere, lithosphere, biosphere 3. Climate describes how the atmosphere behaves over a short period of time (weeks or less) and weather refers how the atmosphere “behaves” over relatively long period of times. False 4. What are the two important facts to consider when talking about sun-earth energy flow? 5. What are the main effects of earth’s rotation and revolution? 6. What are the four types of transfer of energy? By what means is energy transferred at each of them? (Hint: vertical motion; collision; across the vacuum of space; horizontal motion) Conduction- contact b/t two objects ex. Stove top Convection- Vertical mass motion ex. Clouds Advection- transfer of energy horizontal through medium ex. Cold fronts Radiation- Energy transfer in the form of electromagnetic waves w/o medium ex. electromagnetic radiation 7. What is electromagnetic radiation? IS energy emitted by all objects with a wide range of length and frequency 8. What is the law relating the total energy emitted by an object to its surface temperature? Stefan Boltzman Law 9. What is the law relating the dominant wavelength of maximum energy emission of an object to its surface temperature? Wein’s Law 10. A hotter object emits more total energy than a cooler object. True 11. A hotter object emits its dominant energy in a longer wavelength than a cooler object. False 12. The huge sun’s radiant energy is located at the section of the EMR spectrum with long wavelengths. False 13. Place in order, from shortest to largest wavelength, the different regions of the

electromagnetic spectrum (gamma rays, x rays, ultraviolet, visible light, near infrared, infrared, microwave, radio/TV waves)? (gamma rays, x rays, ultraviolet, visible light, near infrared, infrared, microwave, radio/TV waves) 14. Red light has larger wavelength than blue light. True 15. Ultraviolet rays have longer wavelengths than your kitchen’s microwave wavelengths. False 16. The Sun emits its huge energy at longer wavelength than earth’s energy wavelength. False 17. At which type of wavelength does earth emit most of its energy back to the space? Long wave 18. What is INSOLATION? Is a measure of solar energy intercepted by an exposed surface on earth within a period of time 19. Years with more sunspots mean the sun is emitting more solar radiation. False 20. What are the types of variation in insulation? Spatial- Insulation depends on location (Zenith angle, % of rays); Temporal- Annual (Aphelion and Perihelion), Seasonal (Earth’s axis is tilted); Daily (insulation depends on the length of daylight) 21. What are the two annual moments during the year that our planet is placed the nearest and the farthest from the sun? Give the month for each one . Perihelion and
