What causes surface currents to move? Do you think surface currents have an effect on deep ocean currents?

- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)

- Deep is slower, driven primarily by density (salinity and temperature) differences

- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine

- Halocline: dramatic gradient in saline, increase as it deepens

- Pycnocline: resulting change in density (50-1000)

Explanation:

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
