Nina is researching a biome that has warm, humid summers; cold, long, and snowy winters; and at least four to six frost-free months each year. Which region is Nina studying?

The region that Nina is studying with a biome that has warm, humid summers; cold, long, and snowy winters; and at least four to six frost-free months each year are deciduous forests. They are biomes that are identified with the type of weather that changes per season. The trees in this forest loses their leaves as winter and fall came. They are located in between the regions and tropical areas. That is why air masses from both biomes offer to the differences in climate in decidious forest. The annual mean temperature of the forest is about 50°F and rainfall has a depth of about 30 to 60 inches per year. Because of the changes of climate of this biome, many plants and animals have lifestyle that can adapt to these changes.

The biome described is the Deciduous Forest

This biome is is located in the mild temperature zone, and its major regions are located in Eastern North America, Europe and Eastern Asia.

Other characteristics of this biome include the shedding of leaves of trees, and the presence of four seasons. The leaves are shed in fall and grow back in spring.
