50 points. select earthquakes and major plates on the world geology map and observe earthquake activity around the south american plate. based on your observations, what can you conclude about lithospheric motion of the south american plate with the nazca plate and the african plate? explain your answer.

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
