James has three blocks with the same size. He places the blocks in water and observes them. Block A floats in the middle, blocks B sinks to the bottom and C floats to the top of the water. Which statement below can James make about the density of each of the blocks?

• Block A is less dense than block B

• Block C is more dense than block B

• Block B is more dense than block C

• Block C is more dense than block A

Your weight on the moon is about one-sixth of your weight on Earth. Why do you weigh less on the moon?

• The moon exerts a greater gravitational force because it is more dense than Earth

• The moon exerts a smaller gravitational force because it has less mass than Earth

• The moon exerts a greater gravitational force because it is closer to Earth than the sun

• The moon exerts a smaller gravitational force because objects are closer to its center than on Earth
