Answer 2

differences in temperature and salinity.

Step-by-step explanation:

Sea currents are water flows in the oceans that have specific characteristics according to location, in addition to moving continuously. These currents vary in salinity and temperature, which causes a difference in water density, which is what ends up causing them. In this way, they directly influence the planet's climate.

Ocean currents are always circulating between the northern and southern hemispheres, following different directions. This movement is also important for conserving the balance of ocean ecosystems, in addition to being an important factor in orienting fishermen.
