How do the causes of surface and deepwater currents differ?

Surface currents are caused by wind; deepwater currents are caused by differences in water density.

Surface currents are caused by the Coriolis effect; deepwater currents are caused by differences in water density.

Surface currents are caused by differences in water salinity; deepwater currents are caused by differences in water temperature.

Surface currents are caused by differences in water density; deepwater currents are caused by wind.

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

the answer would be a
