Answer:
Environmental Factor
Explanation:
The environmental factors like weather, rainfall, vegetation, etc affected the food and housing of the Native Americans in the Pacific coast and Southwest.
The environment is arid and droughts are common.
In the Southwest, the soil is relatively fertile despite the decrease in moisture content and coarse texture of the soil.
Residents are found along waterways and some areas major in irrigation system of farming due to low rainfall.
Proximity to water affected the people's culture in both farming and hunting.
Most groups of the Southwest were able to cope with the desert environment. As a result of that, they occupied sites on waterways. These groups relied on agriculture for food. Where there are limited access to waterways, others relied on wild foods during each year.
Some of the crops cultivated were corn, beans, squash and cotton.
Some groups lived in riverside hamlets with houses constructed of log frameworks covered with sand and brush.
In the upland areas, houses were dome-shaped with walls and roofs of wattle-and-daub or thatch.
Those in summer residences used lean-tos and windbreaks as shelter during the rest of the year.
