As Earth was forming in its earliest history and probably when the collision that resulted in the formation of the Moon occurred more than 4 billion years ago, Earth was a blob of molten rock with just a thin solid film on its outer surface. Given your experience with materials of different densities, what can you infer about the relative densities of Earth’s atmosphere, ocean, rocky crust and mantle, and iron-rich core?

If you could drill a hole straight to the center of the earth, and keep track of what the hole is going through, youwould find: a) you would go through one sort of material, and then a different, denser material, and then a still-different, still-denser material, because the planet is made of concentric layers, sort of like an onion. b) you would go through one sort of material all the way to the center, because the planet is all mixed up. c) if your hole started at the north pole, you would go through different layers of different materials, but ifyour hole started at the equator, you would go through one sort of material all the way to the center. d) if your hole started at the equator, you would go through different layers of different materials, but if yourhole started at the north pole, you would go through one sort of material all the way to the center. e) you would strike diet pepsi when you got to the center.
