Dellâs XPS 11 2-in-1 Ultrabook really looks the part, and promises a lot. But it falls short in a key, or should we say keyboard, area. Itâs light, performance may not be stunning but itâs perfectly adequate for a notebook this portable, the price isnât extortionate, and battery life is decent too.
The Ring of Fire is a ring of volcanoes around the Pacific Ocean that result from subduction of oceanic plates beneath lighter continental plates. Subduction of oceanic lithosphere. Most of the Earth's volcanoes are located around the Pacific Ring of Fire because that the location of most of the Earth's subduction zones. A subduction zone is a place where one plate of oceanic lithosphere (= the crust + uppermost mantle) is shoved under another plate. The downgoing plate is always the oceanic one.
All of a sudden, the Ring of Fire is starting to tremble violently. Last month, we had a whole bunch of major earthquakes along the Ring of Fire, and this month volcanoes all over the Ring of Fire are erupting. Of course there has always been seismic activity within this giant band that stretches around the Pacific Ocean. After all, approximately 75 percent of all volcanoes are located in the Ring of Fire and approximately 90 percent of all global earthquakes occur along the Ring of Fire. But what is alarming is that the level of activity appears to be rising.
