B Anthropologists believe that the earliest settlers migrated from Asia thousands of years ago
Explanation:
- The first American inhabitants, Paleo-Indians, arrived in the New World with a single, unique wave of migration from Siberia 23,000 years ago, to be divided into today's groups only later, DNA research showed.
- Most scientists agree that the continent was inhabited by people crossing the Bering Land Bridge (at that time there was a crossroads between Siberia and Alaska), and archaeological discoveries so far indicate that humans were present on American soil 15,000 years ago.
- These migrants split into two major groups about 13,000 years ago, at a time when glaciers were melting and roads inland were opening up in North America, experts say.
During the Cultural Revolution, Mao closed down all schools and appealed to the youth to help spread his communist ideas. There were confrontations between Mao’s Red Guards and local police, thus threatening another civil war. The Red Guards started oppressing the intellectuals, who were believed to hold anti-communist views. After Mao, Deng Xiaoping came to power and started focusing on agriculture. He put an end to farmer co-ops. Farmers began cultivating land privately, and agricultural profits increased. Job opportunities increased and people started migrating from rural areas to cities. Deng appealed to the youth to go abroad for higher education. He encouraged foreign countries to do business in China. As a result, China’s economy started growing rapidly.
The Huang He, or Yellow river was very important in Ancient Chinese society. It's called the yellow river because of the huge amount of silt inside of it flowing down. Because of this, the soil around it was very fertile, and this was great for rice farmers.

Answer:
Massive industrial agriculture operations disturbed the solid with large petroleum powered equipment.
Explanation:
The period of dust storms that damaged the agriculture and ecology of Canadian and American prairies during 1930's is called dust bowl. It is called Dust Bowl because choking dust and high winds swept the region from Texas to Nebraska killing livestock and people, the crops also failed in the region affected by Dust bowl.
Extended drought coupled with economic depression, poor agricultural practices, high temperatures and wind erosion all contributed to the Dust Bowl.
The farmers lost their homes and livelihood, and their crop prices fell below the subsistence level due to the Great depression. More than one hundred million acres of the southern plains turned into a wasteland, Texas, Kansas, Oklahoma, New Mexico and Colorado were most affected. There were 14 dust storms in 1932 and 38 in 1933.
The federal government sent the aid to the drought affected states in 1932.
