Textbook Question
Chapter 9, Problem 55EAP
Be sure the show all calculations clearly and state your final answers in complete sentenes.
55. Internal versus External Heating. In daylight, Earth's surface absorbs about 400 watts per square meter. Earth's internl radioactivity produces a total of 30 trillion watts that leak out through our planet's entire surface. Calculate the amount of heat from radioactive decay that flows outward through each square meter of Earth's surface (your answer should have units of watts per square meter). Compare quantitatively to solar heating, and comment on why internal heating drives geological activity.

We think the terrestrial planets formed around solid “seeds” that later grew over time through the accretion of rocks and metals.
a) Suppose the Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On average, how many particles did the Earth capture per second, given that the mass of the Earth is = 5.972 × 10 ^24 kg ?
b) If you stood on Earth during its formation and watched a region covering 100 m^2, how many impacts would you expect to see in one hour. Use the impact rate you calculated in part a. You’ll need the following as well: the radius of the Earth is = 6.371 × 10 ^6 m and the surface area of the Earth is 4??^2Earth
Fully describe the greenhouse effect. How is this important for life on earth?
How is a habitable zone likely to change over time?
a. get narrower
b. move further from the star
c. they aren't likely to change
