C 82% atmosphere, 7% ocean
D 22% atmosphere, 87% ocean
E 52% atmosphere, 57% ocean
Question #4
A how long it takes to measure the salt level
B The average length of time an element spends in the ocean
C The maximum length of time an element spends in the ocean
D The minimum length of time an element spends in the ocean
Question #5
A The concept that the ocean has a uniform pH
B The concept that the ocean has a uniform temperature
C The concept that the ocean has a uniform salinity
D It is a concept that ions are added to the ocean at the same rate as they are being removed
Question #6
A the salt level is variable throughout the ocean
B the ratio of major salts is in constane flux in the ocean
C the ratio of major salts is constant in the ocean regardless of the salinity
D the ratio of major salts is constant unless the salinity changes

A the zone of no light
B the zone of no sound
C the zone of little light
D the zone of light
Question #11
A the surface zone, the pycnocline, the deep zone
B the upper layer, the middle layer, and the lower layer
C the surface zone, the middle zone, and the deep zone
D the surface zone, the pycnocline, the bottom zone
E the pycnocline, the middle zone, the deep zone
Question #12
A Yes. 1000 meters.
B Yes. 1 meters.
C No
D Yes. 100 meters.
E Yes. 3000 meters and deeper
Question #13
A Adhesion leaves no visible remains while cohesion does.
B Adhesion is the property of water molecules to stick to each other. Cohesion is the ability of water to stick to other materials, allows water to cohere to solids, that is, to make them wet.
C There is no difference they are the same
D Cohesion leaves no visible remains while adhesion does.
E Cohesion is the property of water molecules to stick to each other. Adhesion is the ability of water to stick to other materials, allows water to adhere to solids, that is, to make them wet.

C it is a substance composed of two or more elements in a fixed proportion
D it is unique to water
Question #15
A it is a substance composed of two or more elements in a fixed proportion
B it is a substance composed of identical atoms that cannot be broken down into simpler substances by chemical means
