Making Comparisons Thomas Hobbes and John Locke both subscribed to the social contract theory of government. Your local television weather forecast may use millibars, but the scientific community generally uses Pascals for discussing pressure.

Following the path of least resistance, high pressure air flows toward areas of lower pressure. For decades, studying pressure gradients, as well as the related high- and low-pressure systems, has been an important part of weather forecasting.

In the United States, hail is most common in which of the following regions? You can think of this as how much the air pressure (at a particular height, or level, in the atmosphere) changes as you travel from one specific location to another. positive linear correlation 3.
