agriculture

The deliberate effort to modify a portion of Earth's surface through the cultivation of crops and the raising of livestock for sustenance or economic gain.

Agricultural Revolution

The time when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering

crop

any plant gathered from a field as a harvest during a particular season

New technology and increased food production in the second agricultural revolution led to

better diets, longer life expectancies, and more people available for work in factories

different rural land-use patterns.

Patterns of diffusion, such as the Columbian Exchange and the agricultural revolutions, resulted in the
