A  A measure of salinity

B  The terms in which the acidity or alkalinity of a solution is measured. It measures the concentration of hydrogen ions in a solution.

C  The terms in which the acidity or alkalinity of a solution is measured. It measures the concentration of nitrogen ions in a solution.

D  The terms in which the acidity or alkalinity of a solution is measured. It measures the concentration of oxygen ions in a solution.

A  82% atmosphere, 7% ocean

D  78% atmosphere, 48% ocean

E  52% atmosphere, 57% ocean

A  The maximum length of time an element spends in the ocean

B  The average length of time an element spends in the ocean

C  how long it takes to measure the salt level

D  The minimum length of time an element spends in the ocean

A  The concept that the ocean has a uniform salinity

B  It is a concept that ions are added to the ocean at the same rate as they are being removed

C  The concept that the ocean has a uniform pH

D  The concept that the ocean has a uniform temperature

A  the ratio of major salts is constant in the ocean regardless of the salinity

B  the ratio of major salts is constant unless the salinity changes

C  the salt level is variable throughout the ocean

D  the ratio of major salts is in constane flux in the ocean

A  heat capacity of water decreases with increasing salinity

B  as salinity increases, freezing point decreases

C  osmotic pressure increases as salinity increases

D  as salinity increases, evaporation slows

E  all of these

A  ionic

B  simplistic

C  polar

D  covalent

A  Orange

B  Purple

C  Yellow

D  Green

E  Red

F  Blue

A  the zone of no light

B  the zone of light

C  the zone of no sound

D  the zone of little light

A  the pycnocline, the middle zone, the deep zone

B  the surface zone, the middle zone, and the deep zone

C  the surface zone, the pycnocline, the deep zone

D  the upper layer, the middle layer, and the lower layer

E  the surface zone, the pycnocline, the bottom zone

A  No

B  Yes. 3000 meters and deeper

C  Yes. 1000 meters.

D  Yes. 100 meters.

E  Yes. 1 meters.

A  Adhesion leaves no visible remains while cohesion does.

B  Cohesion leaves no visible remains while adhesion does.

C  There is no difference they are the same

D  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.

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.

A  it is a substance composed of two or more elements in a fixed proportion

B  it is a mixture

C  it is a substance composed of identical atoms that cannot be broken down into simpler substances by chemical means

D  it is unique to water

A  it is a substance composed of identical atoms that cannot be broken down into simpler substances by chemical means
