Question

the southwest: the first farming villages north of present - day mexico emerged in the southwest. there, the cultivation of crops required building ponds, dams, and ditches in order to irrigate, or bring water to, the fields. building such complex systems required leadership by a group of priests and chiefs. the hohokams lived in the gila and salt river valleys of present - day southern arizona. over the course of their history, they built more than 500 miles of irrigation canals. the hohokams as canal builders were so elaborate that later peoples returned to the hohokams canals. in their largest village, about 1,000 people inhabited row houses built of adobe, a type of sun - dried brick. some of the houses were three stories tall. the anasazis occupied the upland canyons in the four corners region at the intersection of what is now arizona, new mexico, utah, and colorado. at chaco canyon, the anasazis built an especially complex village that required 30,000 tons of sandstone blocks. this site became the center of the anasazi world. some of the multistory dwellings, known as pueblos, rose five stories and had about 600 rooms.
the mississippians: unlike the arid southwest, the mississippi river valley has a humid and temperate climate. the mississippi river collects the waters of wide - ranging tributaries, including the ohio, missouri, arkansas, and red rivers. the people from this area, known as the mississippians, were influenced by the great cultures of mexico. they built large towns around central plazas, featuring pyramids made of earth. at the top of the pyramids, they built wooden temples that also served as the residences of chiefs. the largest and wealthiest city of the mississippian culture was at cahokia in present - day southwestern illinois. cahokia benefited from being located near the confluence of the missouri, tennessee, ohio, and mississippi rivers. the site provided fertile soil and excellent trade connections with distant groups. at its peak in the year 1100, cahokia had a population of at least 10,000 people and perhaps as many as 40,000. during the twelfth century, cahokias residents abandoned the city. as in the southwest, evidence suggests that an environmental crisis led to social conflict. the growing population had depleted the soil and decreased the numbers of deer. hunger led to disease and to fighting among villages. although cahokia disappeared, mississippian culture still thrived to the south at moundville in alabama, etowah in georgia, and spiro in oklahoma.
