5 A dear, glass beaker is filled half-full of water. A plastic spoon is placed in the
beaker, and one end rests against the top edge of the beaker. When viewed
from the side, the bottom of the spoon does not line up with the top of the
spoon. What causes this to happen?
a:light rays bend the plastic spoon
b:light rays are reflected by the water
c:light rays are refracted by the water
d: light rays are absorbed by the plastic spoon

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.
