Helllppp this is easy but i still don't ! which of the following has a major role regulating global temperatures?
a. oceanic currents
b. ocean layering
c. oceanic chemistry
d. oceanic salinity

Oceanic Currents because temperature is the amount of kinetic energy something has. Since the oceanic currents are used to measure mass and velocity, it is used to measure kinetic energy, therefore measuring temperature. (KE=1/2 x M x V^2)
