A 2,500 km long line of volcanoes, with 80 volcanic mountains and 41 historically active (since 1760 AD) volcanoes produce an arc stretching along the southern edge of the Bering Sea and onto the ...
Some great ideas shake up the world. For centuries, the outermost layer of Earth was thought to be static, rigid, locked in place. But the theory of plate tectonics has rocked this picture of the ...
When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through a ...
The Earth's plates jostle about in fits and starts that are punctuated with earthquakes and volcanic eruptions. 4 min read There are a few handfuls of major plates and dozens of smaller, or minor, ...

Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and upper mantle that fit together like puzzle pieces. Think of these plates as massive rafts floating ...
A geologist has revealed intriguing insights into the volcanic activity on Mars. He proposes that Mars has significantly more diverse volcanism than previously realized, driven by an early form of ...
There’s no geological artist quite like Earth’s plate tectonics. Thanks to this ongoing operation, we have mountains and oceans, terrifying earthquakes, incandescent volcanic eruptions, and new land ...
It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...
Scientists say they have evidence of a new continental rift forming in southern Africa that could eventually develop into a ...
