Textbook Question

Chapter 4, Problem 56IF

Internal vs. External Heating. In daylight, Earth’s surface absorbs about 400 watts per square meter. All of Earth’s internal radioactivity produces a total of 3 trillion watts, which leak out through the surface. Calculate the internal heat flow (watts per square meter) averaged over Earth’s surface. Compare this internal heat flow quantitatively to solar heating, and comment on why internal heating drives geological activity.

CO2 and planetary warming: understanding Earth’s complicated atmosphere Mars has an atmospheric pressure of 6 mbar (compared with Earth atmosphere pressure of 1013 mbar), 96% of which is CO2. The average calculated temperature of Mars is -57°C, whereas the actual average temperature is -55°C so that the amount of warming due to CO2 is only 2°C. On the other hand, the average calculated temperature of Earth, with 0.4 mbar of CO2, is -19°C, whereas the actual average temperature is 15°C so that the amount of warming due to CO2 is 34°C, much greater than that on Mars, which has higher CO2 concentration. Explain how this is possible.

Briefly summarize the evidence linking human activity to global warming. What are its potential consequences?

Eddies- Describe the many ways that eddies might occur. Understand the distinction between warm-core and cold-core eddies. Learn how eddies contribute to the transfer of water masses and organisms. Understand how eddies may lead to varying patterns of convergence and divergence, which affects ocean production.
