Answer:
how did the native americans in the pacific northwest adapt to their environment? the native americans in the pacific northwest adapted to their environment by making things out of wood. they depended on the fish, wildlife, and plants instead of farming.The Native Americans used natural resources in every aspect of their lives. They used animal skins (deerskin) as clothing. Shelter was made from the material around them (saplings, leaves, small branches, animal fur). Native peoples of the past farmed, hunted, and fished.The findings conclusively demonstrate that Native Americans in eastern North America impacted their environment well before the arrival of Europeans. Through their agricultural practices, Native Americans increased soil erosion and sediment yields to the Delaware River basin."Indians cultivated and developed many plants that are very important in the world today. Some of them are white and sweet potatoes, corn, beans, tobacco, chocolate, peanuts, cotton, rubber and gum. Plants were also used for dyes, medicines, soap, clothes, shelters and baskets.
The answer is True. In a convergent boundary, two tectonic plates collide as they move in opposite directions, and there is a subduction zone where there are deep trenches. As the heavier tectonic plate, mostly the oceanic plate, is subducted, it enters the mantle and begins to melt. This makes magma that rises and erupts into a volcano in the overlying continental plate. This is how the Andes Mountains were formed.
