PLATE BOUNDARIES Divergent Boundary Convergent Boundary Transform Boundary
PLATE BOUNDARIES • Divergent Boundary • Convergent Boundary • Transform Boundary
Different Types of Boundaries http: //pubs. usgs. gov/gip/dynamic/understanding. html
Divergent Boundary • Occurs where plates move apart • Effects – SEA FLOOR SPREADING (oceanic) and RIFT VALLEYS (continental)
Divergent Boundary – Arabian and African Plates Arabian Plate Red Sea African Plate
Divergent Boundary – Iceland http: //pubs. usgs. gov/gip/dynamic/understanding. html
Divergent Boundary - Oceanic http: //www. geology. com
Divergent Boundary - Continental http: //www. geology. com
Convergent Boundary • Occurs where plates push together. • Effects – MOUNTAINS (continental) and VOLCANOES (oceanic- due to subduction)
Convergent Boundary – Indian and Eurasian Plates = Himalaya Mountain Range Eurasian Plate Indian Plate
Convergent Boundary – Oceanic & Continental http: //pubs. usgs. gov/gip/dynamic/understanding. html & http: //www. geology. com
Convergent Boundary – Oceanic & Oceanic NOTE – PLATES ARE REVERSED http: //pubs. usgs. gov/gip/dynamic/understanding. html & http: //www. geology. com
Convergent Boundaries - Continental http: //pubs. usgs. gov/gip/dynamic/understanding. html & http: //www. geology. com
Transform Boundary • Occurs where plates scrape past each other. • Effects – EARTHQUAKES
Transform Boundary – San Andreas Fault www. geology. com
HOT SPOTS
Hot Spots • Places where heated rock rises in plumes or thick columns from the mantle • Effects – VOLCANOES
