Answer to Question 1

ANS: A
Covalent bonds are those that form when electrons are shared between atoms. This sharing of electrons
holds the atoms together. Information can be found in the section The Water Molecule Is Held
Together by Chemical Bonds

Answer to Question 2

ANS: A
Red light waves are converted to heat within the first few meters of the surface. In fact, 99 of these
waves are converted by 4 meters deep. Beyond this depth, red objects appear gray in color.
Information can be found in the section Light Does Not Travel Far through the Ocean.
