Which of the following best explains why the engineers used concrete to build this part of the bridge?

• Concrete is low in density so this part of the bridge can float on top of the water.

• Concrete is heavy so this part of the bridge can move back and forth in the wind.

• Making the atoms bigger

• Making the atoms a different shape

• Making larger spaces between the atoms

• Making chemical bonds between the atoms
