The two pieces of information that you need to find density are:

Mass

Weight

Volume

Density

Temperature

Question 2

2.

What are the layers of the mantle in order of least dense to most dense?

Asthenosphere, lithosphere, mesosphere

Lithosphere, asthenosphere, mesosphere

Mesosphere, asthenosphere, listhosphere

Lithosphere, mesosphere, asthenosphere

Question 3

3.

Why doesn't the crust sink into the mantle?

It is more dense than the mantle. 

It is less dense than the mantle.

It is warmer than the mantle.

The oceans hold it up.

Question 4

4.

In this model of the Earth, it says, "Crust (thickness exaggerated)." What does that tell us about this model?

It is not a scale model because the crust should be even thinner.

It is not a scale model because the mantle is too thick.

It is a scale model because the crust is pretty thin.

It is a scale model because all the layers are the right thickness.

Mantle

Crust

Outer Core

Inner Core

How do scientists know what the mantle and core are like?
