Which geographical feature favored the exploration of north america

The extensive and deep penetrating system of rivers inside the continent helped and facilitated the explorations in it.

Explanation:

The deep rooted river systems facilitated the exploration of many coastal regions which were deep inside North America as the European explorers usually travelled in ships. The Mississippi being one of the most important and extensive example of such rivers.

Columbus who is credited the most to the exploration of North America too was able to access it through the coasts and the central American river coasts starting with the Bahamas, Cuba and Hispaniola and spreading to Trinidad and Tobago.

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.
