An active volcano is a volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant. An erupting volcano is an active volcano that is having an eruption.
A Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects.
There is a significant rain shadow effect east of the Rockies. One prime example is Denver. Over the course of a year it would typically receive ~20 inches of rain, but many locations to the west of the continental divide receive as much as 40 inches of rain a year. (It's important to note that the rain shadow effect only impacts storms and winds traveling against the mountains. If a storm travels south to north, the effect is severely diminished and can result in a situation where the lee side of the mountains receives more rainfall than the wind side of the mountains.

It has been reported that glaciers lost more than nine trillion tons of ice which in turn led to a twenty seven (27) millimeter increase in global sea levels over the period in review.
