Климат и природные ресурсы.
Соединенные Штаты — это страна контрастов. Природа, климат, население страны изменяются с восточного побережья на западное, с северной границы на южную.Климат на большей части умеренный, тропический на Гавайях и в штате Флорида, арктический на Аляске, полузасушливый на великих западных равнинах реки Миссисипи и полупустынный на юго-западе.Природные ресурсы включают: уголь, медь, свинец, молибден, фосфаты, уран, бокситы, золото, железо, ртуть, никель, серебро, вольфрам, цинк, нефть, природный газ и древесину.Природные катаклизмы представляют огромную проблему для США. Каждый год страна теряет сотни миллионов долларов из-за природных катаклизмов. США известны своими ураганами вдоль атлантического побережья и побережья Мексиканского залива, торнадо на среднем западе и юго-востоке, грязевыми оползнями в Калифорнии, лесными пожарами на западе, наводнениями.Иногда наблюдаются цунами, вулканы и землетрясения. Очень часты землетрясения в Калифорнии.Говоря об окружающей среде, необходимо добавить, что загрязнение воздуха выливается в кислотные дожди как в США, так и в Канаде. США — самый крупный «производитель» двуокиси углерода от сжигания ископаемого топлива.Имеет место и загрязнение воды из-за сброса пестицидов и удобрений.
