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).

<h3>What are the reasons for location considering the availability of water, flat land, fertile soil, climate, weather, grazing land, etc?</h3>
- The reason for location considers the availability of water, flat land, fertile soil, climate, weather, grazing land, safety, Transport routes, mining, minerals, past history, and cultural, and economic factors that it will be beneficial for the cultivation of the planted crops.
- Another reason is that it will be easier for farmers.
- The next reason is that it will be that the crop will be healthy.

The faults in which the hanging wall moves down relative to the footwall is called normal fault.
Explanation:
There are several types of faults based on their characteristics. One of them is the normal fault, or normal dip-slip fault. The main characteristic of this fault is that its hanging wall moves down relative to the footwall, while the footwall tends to move up relative to the hanging wall. The force that creates this type of faults is the vertical compression as the crust of Earth is lengthening.
- These faults can be found all over the world, and they are actually the most common type of faults.
- The normal dip-slip faults are bounding big portion of the mountains, as well as rift valleys.
- As these faults progress with their formation, with the footwall going up, and the hanging wall going down, the footwall becomes a hill or a mountain, while the hanging wall becomes a valley.
- The normal dip-slip faults can be found at all types of tectonic plate boundaries.
