Answer:
Large population centers, or urban areas (1), allow civilizations to develop, although people who live outside these urban centers are still part of that region’s civilization. Rural residents of civilizations may include farmers, fishers, and traders, who regularly sell their goods and services to urban residents.
The huge urban center of Teotihuacan, in modern-day Mexico, for example, had as many as 200,000 residents between 300 and 600 CE. The development of the Teotihuacano civilization was made possible in part by the rich agricultural land surrounding the city. As land was cultivated, fewer farmers could supply more food staples, such as corn and beans, to more people.
Trade also played a part in Teotihuacan’s urban development. Much of the wealth and power of Teotihuacan was due to excavating and trading the rich deposits of obsidian around the city. Obsidian is a hard volcanic rock that was highly valued as a cutting tool. Teotihuacano merchants traded (exported) obsidian to surrounding cultures in exchange for goods and services imported to Teotihuacano settlements.
Answer:1111 Km.
The circumference of the earth is about 40,000 kilometers and the earth has a total of 360 degrees.
If you want to know what 10 degrees is equal to, use a simple proportional equation.
10 X
------ = -------
360 40,000 km
Then, solve for X.... (cross multiply)
(10*40,000)/360= 1111.1111111

I think the correct answer is false. Most of North America do not have the same climate type. Climate can differ all over the U.S. One moment it can be 100 degrees in Texas and In Ohio it can be only 60. Hope this answers the question. Have a nice day.
Convection. It occurs when a cooler, denser mass of gas or liquid replaces a warmer, less dense mass of gas or liquid by pushing it upward. A good example would be steam rising from a pot of boiling water on a stove top.
When the water is boiled, the water moves in roughly circular patterns because of convection. This motion is due to density differences that result from temperature differences. Also referred as a convection current.
Hope this helps you out.
