Dynamic Earth

__ Divergent Boundaries __ -Magma rises and pushes plates apart.

Process:Sea-floor spreading

EX:Mid-Atlantic Ridge,East pacific rise.

Characteristics:Mid-Ocean ridges,Rift valleys,Earthquake activity at fracture zones along mid-ocean Ridges,Volcanic activity

__ Convergent Boundaries __ -A plate collides with or goes under another.

​ Process:Ocean-Ocean Subduction/Ocean-Continent Subduction/Continent-Continent Collision

​ EX:Islands of Indonesia,Marina Islands/​Western Coast of South America/Himalayes

​ Characteristics:Deep-Sea Trenchses,Volcanic Island Arcs,Earthquake Activity/Deep-Sea Trench Bordering Continent,Volcanoes Along Coast of Continent,Earthquake Activity/High Continental Mountain Chains,Earthquake Activity

__Transform Boundary__-A boundary between two plates that are sliding past each other Process:Plates sliding past each other.

Ex:San Andreas Fault,North Anatolian Fault(Turkey),Fracture Zones Along Mid-Ocean Ridges.

Characteristics:Earthquake Activity.
