The homes of the Indians were copied by the English, being ready adaptations of natural and plentiful resources. Wigwams in the South were of plaited rush or grass mats; of deerskins pinned on a frame; of tree boughs rudely piled into a cover, and in the far South, of layers of palmetto leaves. In the mild climate of the Middle and Southern states a 'half-faced camp,' of the Indian form, with one open side, which served for windows and door, and where the fire was built, made a good temporary home. In such for a time, in his youth, lived Abraham Lincoln. Bark wigwams were the most easily made of all; they could be quickly pinned together on a light frame. In 1626 there were thirty home-buildings of Europeans on the island of Manhattan, now New York, and all but one of them were of bark."Alice Morse Earle, Home Life in Colonial Days, 1898 Americans Indians had significant, immediate influence on the colonists and their communities on the Atlantic Seaboard because (1 point) permanent villages aided the colonists in forming political alliances and allocating resources found in the Americas the colonists arrived with a need to build shelters but didn't understand the materials or tools available the weather conditions on the Atlantic Seaboard were foreign to the colonists, and they sought help from the native peoples they were familiar with the farming techniques that the colonists needed to establish their permanent communities Which describes a climate effect on the rate of weathering? Cold climates favor mechanical weathering. Chemical reactions occur slower at higher temperatures. Lower precipitation levels lead to more chemical reactions. The chemical reaction rates of minerals are not impacted by temperature. please help.. GP is geometric progression I NEED HELP PLEASE, THANKS!

D) congruence. Which major architectural influence is illustrated by the photo above? The use of Corinthian columns and semicircular arches demonstrates the influence of classical architecture. The inclusion of glass windows points towards access to sophisticated glass manufacturing from the Arab world. The presence of geometric patterns represents a uniquely northern European addition to the structure. The use of decorative tile along the covered walkway is a common technique borrowed from Byzantine architecture. 4. The dimensions of a triangular pyramid are shown below.
