Explanation:
The major factor that influences the strength of rocks is the rock type. 
Different rock types are known to have their own relative strength. 
Based on their strength, rocks are classified into hard and soft rocks. 
Soft rock types are dominated by sedimentary rock. Sedimentary rocks are formed by accumulation and deposition of sediments. They are often layered. 
Metamorphic and igneous rocks are usually classified as hard rocks. These rocks forms under very high temperature and pressure conditions. 
In engineering applications, the soft rocks not desired for construction purposes although they have their own unique material functions. 
Hard rocks are used for heavy duty and durable constructions like dams and bridges.

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).
