Standard air pressure at sea level is the equivalent weight of a column of air __15___ miles tall and one inch square.
Explanation:
This is as much as a substantial amount of the atmosphere extends up almost into space. However, remember that air pressure decreases the higher into the atmosphere you go because the density of air decreases the higher you go. Half of the air molecules are found about 18,000 feet high from the earth’s surface.
A square inch of the atmospheric air exerts a pressure of 14.7 pounds per inch squared from the ‘weight’ of the air column above - equivalent to 29.92 inches of mercury.

Canada ranks 38th by population, comprising about 0.5% of the world's total,[2] with over 37 million Canadians as of 2019.[3] Despite being the fourth-largest country by land area (second-largest by total area), the vast majority of the country is sparsely inhabited, with most of its population south of the 55th parallel north and more than half of Canadians live in just two provinces: Ontario and Quebec. Though Canada's population density is low, many regions in the south such as the Quebec City–Windsor Corridor, have population densities higher than several European countries. Canada's largest population centres are Toronto, Montreal, Vancouver, Calgary, Edmonton and Ottawa with those six being the only ones with more than one million people. The large size of Canada's north which is not arable, and thus cannot support large human populations, significantly lowers the country's carrying capacity. Therefore, the population density of the habitable land in Canada can be modest to high depending on the region.
The historical growth of Canada's population is complex and has been influenced in many different ways, such as indigenous populations, expansion of territory, and human migration. Being a new world country, immigration has been, and remains, the most important factor in Canada's population growth.[4] The 2016 Canadian census counted a total population of 35,151,728, an increase of around 5.0 percent over the 2011 figure.[5][6] Between 1990 and 2008, the population increased by 5.6 million, equivalent to 20.4 percent overall growth.[7]
This is true. Temperate grasslands are found in several regions across the globe. This includes but is not limited to the midwestern United States. The area is usually very flat and consists of grasses and shrubs.
