Why did german declare war on Russia

Explanation:

Germany declared war on Russia on 1 August and France on 3 August. Germany's violation of Belgian neutrality and British fears of German domination in Europe brought Britain and its empire into the war on 4 August. These actions reflect the fears, anxieties and ambitions of the European powers.

both eastern and western early north american cultures were known for building wigwams and longhouses.

wigwams, also called wetus, were small houses of 8-10 feet tall, made of wooden frames covered with woven mats and sheets that were used by algonquian indians. similarly,   longhouses were also used by algonquian and the iroquois tribes, and they were built as well with pole frames and elm bark covering. however, the main difference between wigwams and longhouses is that the latter was much larger than the former, with 200 feet long, 20 feet wide, and 20 feet high with inner raised platforms used for sleeping space.
