Answer:
These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.

Answer: Polarization
Explanation: Polarization is the movement of electrons within a neutral object because of the electric field of a nearby charged object. It occurs without direct contact between the two objects.
For example, electrons in a metal plate can repelled by the negative charges in a plastic rod if the plastic rod is placed near the metal plate. The electrons move away from the plastic rod, thereby causing one side of the metal plate to be positively charged and the other side to become negatively charged.
The frequency of any wave is (wave speed) / (wavelength) .
The speed of light is 3 x 10⁸ m/s.
If the wavelength is 10 nm (10⁻⁸ m) , then the frequency is
(3 x 10⁸) / (10⁻⁸) = <em>3 x 10¹⁶ Hz</em>
That's 30 million gigahertz !
