deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses Lesson 2.12

Question 3 options:

Density

Thermohaline currents

Salinity

Polar ice caps

I'm pretty sure it's Density

Explanation:

Density differences in water masses due to temperature and salinity variations which makes a process known as thermohaline circulation. These currents move water through the ocean taking nutrients, oxygen, and heat with them.

its B) Thermohaline currents  Sorry if its wrong but im sure this could be it

Explanation: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. In the Earth's polar regions ocean water gets very cold, forming sea ice.

a is the answer to this question

explanation:

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.
