Question

complete the table below. see the previous page or look in todays slides for hints. plate boundaries convergent oceanic/continental type: movement: result: example: convergent oceanic/oceanic type: movement: result: example: convergent continental/continental type: movement: result: example: divergent oceanic/oceanic type: movement: result: example: divergent continental/continental type: movement: result: example: transform type: movement: result: example:

Explanation:

Convergent oceanic - continental: Type is subduction, oceanic plate moves under continental plate, results in volcanic arcs and mountain - building (e.g., Andes). Convergent oceanic - oceanic: Type is subduction, one oceanic plate moves under another, results in island arcs (e.g., Mariana Islands). Convergent continental - continental: Type is collision, plates move towards each other, results in high - mountain ranges (e.g., Himalayas). Divergent oceanic - oceanic: Type is seafloor spreading, plates move apart, results in mid - ocean ridges (e.g., Mid - Atlantic Ridge). Divergent continental - continental: Type is rifting, plates move apart, results in rift valleys (e.g., East African Rift). Transform: Type is sliding, plates slide past each other horizontally, results in earthquakes (e.g., San Andreas Fault).

Answer:

Plate Boundaries	Convergent Oceanic/Continental	Convergent Oceanic/Oceanic	Convergent Continental/Continental	Divergent Oceanic/Oceanic	Divergent Continental/Continental	Transform
Movement	Oceanic plate moves under continental plate	One oceanic plate moves under another	Plates move towards each other	Plates move apart	Plates move apart	Plates slide past each other horizontally
Result	Volcanic arcs, mountain - building	Island arcs	High - mountain ranges	Mid - ocean ridges	Rift valleys	Earthquakes
Example	Andes	Mariana Islands	Himalayas	Mid - Atlantic Ridge	East African Rift	San Andreas Fault
