Lecture 21- Marine Chemistry 1 Flashcards
1
Q
evaporation
A
- moves latent heat from the ocean to the atmosphere in the form of water vapor
- atmosphere then transports this heat to other parts of the planet
2
Q
condensation
A
latent heat released into the atmosphere as sensible heat to form clouds and rain
3
Q
total amount of salt contained in the entire ocean is
A
essentially constant
4
Q
local differences in surface salinity are caused by
A
local differences in the addition and removal of water NOT SALT
5
Q
What has the greatest contribution of ion in seawater by weight?
A
- Cl-: 55%
- Na+: 31%
- SO4-: 8%
6
Q
salinity is a direct function of
A
evaporation minus precipitation
7
Q
high latitude
A
- low surface salinity
- high precipitation
- low evaporation
8
Q
tropics
A
- high surface salinity
- high evaporation
- low precipitation
9
Q
equator
A
- dip in surface salinity
- high precipitation offsets high evaporation
