Identify the control group the experimental group the independent variable and the dependent variable. A new sunscreen has been
developed that is supposed to be
more effective at preventing
sunburn. 30 participants spray
one arm with
the new formula, and spray the
other arm with the leading
formula. After 4 hours in the sun,
their skin is evaluated for any
redness.

How do temperature and salinity affect deepwater currents? question 15 options: 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.
