Further adding to the consequences‚ such a sea level rise could cause extensive erosion of the continents‚ islands and possibly other ice caps. The extra infrared radiation captured by atmosphere through the greenhouse effect is transferred into the Arctic ice caps as potential energy where the water (H2O) molecules vibrate faster and break their bonds due to the process of latent heat‚ where the temperature of the ice is prevented from falling or rising until the bonds break and a state change occurs

The region includes one of the major mountain ranges in Alaska‚ the Brooks Range‚ as well as some of the most important economic resources and reserves in the United States. This region is composed of varying sizes of plutons‚ batholiths and sedimentary rocks. Two major terranes encompass the region‚ the Arctic Alaska terrane and the Angayucham terrane as well as their associated
