Question

when a denser oceanic plate is pushed underneath a less dense continental plate, in a process called ____________, a deep wedge or valley called a __________ is formed. when two oceanic plates converge, the ocean floor can be pushed up to form a __________ __________ __________ along a trench. the best example of this is the island nation of __________. when two continental plates converge, neither plate is dense enough to subduct, and they simply push up to form __________ __________. the best example of this process are the __________. transform plate boundaries exist where plates __________. the best example of a transform boundary is __________. a __________ __________ is an area of hot upwelling magma called a mantle plume. the best example of this is the island chain of ____________.

Explanation:

1. When a denser oceanic plate is pushed beneath a less - dense continental plate, it's subduction and a trench is formed.
2. When two oceanic plates converge, volcanic island arcs can form, like Japan.
3. When two continental plates converge, mountain ranges form, such as the Himalayas.
4. At transform plate boundaries, plates slide past each other, and the San Andreas Fault is a well - known example.
5. A hot spot is an area of hot upwelling magma, and the Hawaiian Islands are formed by a hot spot.

Answer:

1. Subduction; Trench
2. Volcanic island arc; Japan
3. Mountain range; Himalayas
4. Slide past each other; San Andreas Fault
5. Hot spot; Hawaiian Islands
