In noting that the earth is "differentiated," we mean thatGroup of answer choicesthe radioactive heating in the core is increasing with time.the density increases as you descend downward toward the core.the earth's magnetic field varies at different locations on the globe.the earth is very different than any other planet we study.the density of oceanic basalt is less than that of granite on the mountain tops.

If the earth's differentiation were any different, its gravitational pull and might have been affected.

the earth's crust varies from 8km to 40 km what does this show?

If the Earth is represented as a bar magnet, state which magnetic pole of the bar magnet would be closer to geographic north.

Describe how the composition of the Earth's layers changes with depth.

Which of these supports the idea that Earth’s Core is largely liquid iron?Group of answer choicesEarth’s large mass can only be explained by large amounts of a heavy element in its interiorEarth’s magnetic field points to the presence of a metallic liquid in its interiorS-waves are absorbed as they travel through Earth’s deep interiorAll of these taken together are the basis for the present model of Earth’s Core
