During the second half of the 20th Century, a consensus emerged among North American archaeologists that the Clovis people had been the first to reach the Americas, about 11,500 years ago. This is the way America got populated.
<h3>What are major changes occurred in America's population?</h3>
In 2006, America's population reached 300,000,000 inhabitants. According to the estimates of the US Census Bureau, at the end of 2019 the American population will exceed 330 million people. As can be seen, it is a population in constant increase, both for its positive birth rate and for the high rates of immigration that arrive in the country every year. With these numbers, a percentage of annual population growth of 0.62% is determined.
This amount of population makes the United States the third most populated country in the world, only behind China and India (which have 1.4 billion and 1.35 billion inhabitants, respectively).

Um, I disagree. Maybe you should take some time to understand how Earth works!
Answer: A. 101.3 kPa
Explanation:
By experiment, standard sea-level pressure = 760 mm (29.92 inches) of mercury, which also = 14.70 pounds per inch², which also = 1,013.25 × 103 dynes per cm², which also = 1,013.25 millibars, and one standard atmosphere = 101.325 kPa.
Therefore, the unit of pressure that represents the force exerted by the atmosphere at sea level is 101.3 kPa
