Test: Layers of the Earth & Density

The formula for density is

• volume/mass

• mass/volume

• mass x volume

• density x mass

If an object is less dense than water it will

• sink when put in water

• sink when put in quicksand

• float when put in water

• float when put in outer space

How does the density of the wood block compare to the density of the water in the picture?

• The wood is the same density as the water.

• The wood is less dense than the water.

• The wood is more dense than the water.

• The density of the wood is changing.
