Types of Plate Boundaries andTheir Physical Impacts
Divergent Boundaries: Where Plates Separate
At divergent boundaries, tectonic plates mountain move apart. Most are located along thee mid- oceaun ridge system, a 65,000 -kilometer- long underwater tountain chain that snakes thraigh all the contracted d 's oceans. As plates separate, magma rises frem the mantle te fill the gap, coils, and forms new oceanic cross. This process, called seawour spreading, continousy create thee oceain four.
On land, divergent boundaries create rift valleys. The Eass African Rift System is a prime example: thee African plate is splitting apartt along this fault zone, creating a serie of deep valleys, wulcan, and lakes. Over tens of millions of years, this rift will likely evolvne into a new ocean basin, separating thee Horn of Africa from the mainland.

Konwergent Boundaries: When Plates Collide

Thee San Andreas Fault System
Te San Andreas Fault is a transform boundary that runs approximately 1,300 kilometer through gh California. The Pacific plate moves northwest relative to the North American plate at about 3.5 cm / year. The fault is nota a single breake but a zone of multiple parallel faults. Over geological time, this slip has moved Los Angeles (on thee Bacfic plate) about 400 kilometers northweste relative to San Francisko (one North Americtale).
Earthquakes alonge fault have shaped California 's geography. The 1906 San Francisco thirgake (estimated magnitude 7.9) offset thee ground by up to 6 meters, destruyed much of the city, and caused extensive fires. The fault creats linear valleys, such as the Carrizo Plain, where streas ridges are offset. These offsets help geologists metricure long-term slip rates.
