WebVolcanic eruptions can influence climate and global temperature because of the gases and dust particles spewed into the atmosphere during the eruption. WebVolcanism also occurs in areas that are not associated with plate boundaries, in the interior of plates. These are most commonly associated with what is called a hot spot. Hot spots appear to result from plumes of hot mantle material upwelling toward the surface, independent of the convection cells though to cause plate motion. cnrv hospital in radford virginia https://traffic-sc.com
