Emissions of sulfur dioxide by industry set off chemical changes in the atmosphere that result in "acid rain". the acidity of liquids is measured by ph on a scale of 0 to 14. distilled water has ph 7.0, and lower ph values indicate acidity. normal rain is somewhat acidic, so "acid rain" is sometimes defined as rainfall with a ph below 5.0. the ph of rain at one location varies among rainy days according to a normal distribution with mean 5.43 and standard deviations 0.54. what proportion of rainy days have rainfall with ph below 5.0?

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. 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.
