The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

The boundary where the two plates meet is called a convergent boundary. Deep trenches appear at these boundaries, caused by the oceanic plate bending downward into the Earth. Deep below the Earth ...

Plate tectonics is the widely accepted theory that ... while the other is pushed downwards where it melts. This is a convergent boundary. Scientists have wondered for many decades whether the ...

For more on divergent boundary, go to The Sea Floor Spread. Also known as subduction boundary, a convergent boundary occurs where one plate slides under another as the two are pushed together.

The movement of these tectonic plates leads to earthquakes and volcanoes ... This is called a destructive or convergent plate boundary. When the plates collide, the denser plate, usually the ...
