A scientist performs an experiment where she measures the mass of a piece of metal, pours acid onto the metal, washes the metal, and then re-measures the mass of the metal. The scientist repeats the experiment several times
each time increasing the amount of acid used.
The dependent variable in the experiment is the

A. Initial mass of the metal

B. Final mass of the metal

C. Amount of acid used

D. Washing the metal

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

How does climate change cause the ocean's thermohaline current to slow down?
