location of volcanoes
Let's carefully examine the edges of colliding plates to see why volcanoes might be found there. Remember that the plates move because heat flowing up from Earth's core causes mantle rock to slowly flow in giant convection currents. The rigid plates ... or continental crust. So when plates collide, we have only three possibilities: oceanic ...

These plates actually move around! The study of how these plates move is called plate tectonics. Today we know that they move at approximately the same speed at which your fingernails grow. All the plates ...

New Zealand is located along a zone of contact between the Pacific and Australian tectonic plates. Here as elsewhere in the world the distribution of major earthquakes follows the boundaries between ... (sinks). In the South Island the contact between the two plates is different and forms the Alpine Fault. There the two plates move sideways relative to each other, with a total displacement so ...

Earth Science | geology | A lesson in plate tectonics
In other converging boundaries, there is no volcanic activity because the tectonic plates are both continental plates, weighing the same. No subduction happens along these margins, just massive deformation ... two plates are sliding and scraping past each other. The resulting strain from the sliding action of the plates causes cracks in the crust called faults. As the larger plates move past ...

Earthquakes--Forces of Nature--Science, Maps, Photos, Video (National Geographic)
The Earth's plates are constantly moving and interacting in a process called plate tectonics—they push against each other, pull apart, or grind past one another. Usually the plates move very gradually. Occasionally, however, stress builds up and is released suddenly in a great burst of seismic waves. These vibrations move through the rock, causing an ...
