Here's why:
* No Creation or Destruction: Unlike convergent or divergent boundaries, transform boundaries don't involve the creation or destruction of the Earth's crust.
* Lateral Motion: The plates move horizontally past each other in opposite directions.
* Friction and Earthquakes: This sliding motion generates significant friction, leading to frequent earthquakes along these boundaries.
Famous Examples:
* San Andreas Fault (California, USA): This is a prime example of a transform boundary where the Pacific Plate is sliding past the North American Plate.
* The Alpine Fault (New Zealand): The Pacific Plate moves northward relative to the Australian Plate along this fault.
