tendency of molecules of the same kind to stick to one another

• cohesion

• adhesion

• solution

• polar molecule

How would you classify layer C?

• aquifer

• permeable

• impermeable

• zone of saturation

Small insects can walk across the surface of calm water. Their feet push the surface of the water down slightly, somewhat like a person walking across a trampoline, but they do not break the surface. What is the best explanation for why this happens?

• The insects are light enough so that they do not break the hydrogen bonds holding the water molecules together

• The insects actually use their wings to hover slightly above the water's surface and they only skim it with their feet

• The insects' feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water's surface

• The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next

Water has a much higher specific heat than most other covalent compounds. What do you predict might happen if water had a low specific heat instead?

• Flooding would occur and animals would be forced to migrate

•  Harmful organisms living in water would reproduce at a rapid rate

• Organisms that are sensitive to changes in temperature would die

• Plants would not have enough water to effectively carry out photosynthesis

To use water found in an aquifer people would

• build a dam

• drill a well to below the water table

• purify ocean water
