How did the environment influence the cultures of the northwest and southwest? (this is about native american cultures)

2-4 sentences : ) thx

Traditional Native American cultures vary extensively rely on tribes or clans, with hundreds of them in America, northwest and southwest included.

Some settlements were concealed by mountains and plains. Thus people in the plains relayed on corn, squashes and beans like the Mandan living in villages; others were moving herds like the Lakota.  

People in the NW areas depended on the sea, being experts in whaling, fish oil trade, and salmon breeding.  

Native American quotidian practices fluctuate from using animal skins as clothing, shelters made from the surrounding materials to using resources like rocks, or oyster shells to farm, hunt, and fish.

People of the Northwest Coast wore minute clothing, excepting when it was cold; having a high metabolic rate allowed them to produce body heat, often remaining naked, or barely wearing bushy clothes from animal leather, or wool.

And the Southwest's climate is generally hot and arid, with rock formations, water-miser plants, and few green river valleys, so the cultures from that region were based on farming supplemented by hunting and gathering.
