Plate Tectonics Unit Project Plate boundaries and Human Impact

Transform Boundary Characteristics Transform Plate Boundaries are locations where two plates slide past one another. Pressure forms when plates get “stuck” Earthquakes occur when plates move and pressure is released The Earth’s crust is neither created or destroyed at a transform boundary The fracture zone that forms a transform plate boundary is known as a transform fault. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges. A smaller number connect mid-ocean ridges and subduction zones. A smaller number of transform faults cut continental lithosphere. Transform boundaries are also known as Strike-Slip Faults. Earthquakes can also cause tsunamis.

Examples of Transform Boundaries The San Andreas Fault Zone of western North America, located in California and Mexico, is the most famous example. © 2005-2010 Geology.com Another example of a transform boundary on land is the Alpine Fault of New Zealand An example of a transform boundary in an ocean basin is in the Caribbean This boundary has a transform fault that caused the Haitian Earthquake of 2010

Human Impact of Plate Tectonics Haitian Earthquake January 12, 2010 ©buzzybloggers.com © AP Human Impact of Plate Tectonics An estimated three million people were affected by the quake. The Haitian Government reported that an estimated 230,000 people died. This makes the Haitian earthquake the 4th most deadly earthquake ever. An estimated 300,000 were injured and 1,000,000 made homeless. An estimated 250,000 homes and 30,000 businesses collapsed or were severely damaged. 7.0 magnitude earthquake, epicenter located only 16 miles from the country’s capital of Porte-au-Prince.
