Concrete masonry units (CMU) are some of the most commonly used materials in building construction. Due to their relatively low cost as wall material and their fire resistance, CMU walls are laid on many types of projects. From schools to warehouses, many buildings have CMU walls.
History >> Native Americans for Kids. The Inuit people live in the far northern areas of Alaska, Canada, Siberia, and Greenland. They originally made their home along the Alaskan coast, but migrated to other areas. Everything about the lives of the Inuit is influenced by the cold tundra climate in which they live.
Inuit are the descendants of what anthropologists call the Thule culture, who emerged from western Alaska, after crossing from Siberia, around 1000 CE and spread eastwards across the Arctic. They displaced the related Dorset culture, the last major Paleo-Eskimo culture (in Inuktitut, called the Tuniit).
