WORLD HISTORY

Detailed explanation-1: -Yet, mountains contain more diversity than plain regions: their varied landscapes and the changes in altitude have created a multitude of agro-ecological zones. The genetic variety of agricultural crops and farm animals contained in these zones has the potential to provide diversified and nutritious food for all.

Detailed explanation-2: -Farmers grow crops by cutting steps in mountains and not on plains. This kind of farming is done in hilly areas so that the rain water won’t carry away the soil needed for plants.

Detailed explanation-3: -The soil was rocky, which made farming difficult. The New England colonies had very harsh winters and mild summers. This made the growing season only about five months long. Because the soil was rocky and the climate was often harsh, colonists in New England only farmed enough to feed their families.

Detailed explanation-4: -When early humans began farming, they were able to produce enough food that they no longer had to migrate to their food source. This meant they could build permanent structures, and develop villages, towns, and eventually even cities. Closely connected to the rise of settled societies was an increase in population.

Detailed explanation-5: -Egyptians were among the first peoples to practice agriculture on a large scale, starting in the pre-dynastic period from the end of the Paleolithic into the Neolithic, between around 10, 000 BC and 4000 BC.
