If matter (mass) has never been observed by any process or experiment to be created or destroyed, then using inductive reasoning it would be logical to conclude: the mass of the universe must have created itself.
the known laws of science cannot account for the origin of mass.
the amount (quantity) of mass in the universe has never changed.

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.
