Reading for this week Chapter 2: The Internal Structure of the Terrestrial Planets If you haven’t finished reading the chapter, keep working on it. If you have just skimmed it, look back at it, looking especially for the topics I talk about in class. Get started on reading chapter 3: Volcanism. We will wait until Friday for the quiz to give you time to read it.

ABCD Quiz Assume Mars has the same internal composition and the same density as the Earth, but ½ the diameter of the Earth. How does the mass of Mars compare to the mass of the Earth? D. Mars has 1/8 the mass of the Earth Volume is proportional to width cubed, so is (1/2) 3 = 1/8 as large. If their densities are the same, mass is proportional to volume, so the mass of Mars is also 1/8 the mass of the Earth.

ABCD Quiz So the rate of heat generation inside of Mars is 1/8 the rate inside of the Earth (if their compositions are the same). How about the rate of heat loss from the surface?
