Between 10,000 and 100,000 years ago, much of the world was covered by glaciers or thick sheets of ice. As more and more of the world’s water froze, the level of the oceans dropped. Areas that once were covered by shallow water became dry land. One of these areas was between Asia and North America. It became a bridge of land…Many scientists believe that people first came to North America between 20,000 and 30,000 years ago.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
