Continents X and Y crash together, increasing the subduction mountain range. mountain's creation process produces rounded-top chains, the Black Hills of South Dakota serving as a good example. Vulcanism also results in the most obvious mountain creation volcanoes. Although volcanoes are usually associated with subduction of tectonic plates, some places are simply hot spots, or places that allow magma to rise near the surface. Although volcanoes are spectacular and dangerous, they are not very...

Thick, the lack of light under the canopy only allows certain plants to flourish. Thick carpets of mosses grow in the dim light under the spruces and firs while lichens thickly grow under the pines where there is slightly more light. This vegetation (along with the layer of undecomposed needles) acts as an insulator to the permafrost. The colder the soil becomes, the more the permafrost moves towards the surface, and the less soil is available to tree roots. During periods of early warm...
