How are southern appalachian (u. s.a.) and southwestern caucasus (russia) forests similar?

The correct answer is (B) They are both Northern Hemisphere, warm-temperate forests. Although Appalachian (U.S.A.) and Southwestern Caucasus (Russia) have common origins, both northern hemisphere warm-temperature Tertiary forests, they have developed differently.
