Geoscience Text Images & Small Group Discussion Temp vs Heat Sources of Heat Heat Transfer Energy Balance

1. Compare and contrast the GS and Physical Science definitions of temperature and heat.

(see question 2 on the next slide)

2. List and describe the Earth’s three sources of heat outlined in the text.

3. What is radiation? 4. How does radiation differ from convection and conduction?

5.

5. How does the air become warm? 6. What is conduction? 7. What conditions are necessary for conduction to occur?

8. What is convection? 9. Describe in detail the process of convection. 10. Convection currents are among the main mechanisms responsible for the vertical motions of air, which in turn cause the different types of __________.

SEE IMAGE ON NEXT SLIDE FOR HELP… 11. What happens to the area illuminated by sunlight as the rays strike the ground at a lower angle? (at the poles) 12. What happens to the relative intensity of the sunlight as it strikes a lower angle? (at the poles) 13. How is this different than what occurs at the equator? (impact angle and relative intensity)

14. How do regions manage to maintain fairly constant average temperatures?
