      Compare the actions of converging and diverging tectonic plates.

    Answer:

      Convergent boundaries occur when two plate slide toward each other to form either a subduction zone or a continental collision. When two tectonic plates converge, the crust is destroyed and recycled back into the interior of the Earth as one plate dives under another. Mountains and volcanoes area often found where plates converge. The Himalayas were formed due to the converging of the Eurasian plate with the Indo-Australian plate. As divergent boundaries, new crust is created as two plates pull away from each other. Oceans are born and grow wider where plates diverge or pull apart. When a diverging boundary occurs on land, a 'rift' will arise and the mass of land will break apart into distinct land masses. A divergent boundary between the North American and Eurasian plates has caused a ridge in the middle of the Atlantic Ocean.                                     (5)
