Plate Tectonics

Volcano

________ can form in convergent boundary when the two plates collide the denser plate sinks, or subducts into the mantle and in Divergent Boundary the two plates spread apart.

Convection Current

________- causes the plates to move.

volcanic arc

A(n) ________ is formed as a result of oceanic- continental.

Island Arc

A(n) ________ is formed as a result of oceanic- oceanic.

Footwall

________- lies below the fault surface.

Boundary

It is an area where two plates meet is called Plate ________.

Subduction

________- an event which the sub of rock thrusts into the mantle.

Divergent Boundary

________- is where the two plates move apart.

Convergent Boundary

________- is where the two plates moves towards each other.

PHIVOLCS

________- Philippine Institute of Volcanology and Seismology.

Active Volcanoes

________- that have a history of eruption.

mountain range

A(n) ________ is formed through continental- continental, the best example of it is the Mount Himalayas in South Asia.

Inactive Volcanoes

________- those who have none, also have a signs of physical change due to weathering and erosion.

Plate Tectonics

movement of the plates over Earths surface

Theory of Plate tectonics

is the theory that can explain the tectonic and geologic processes that occur on Earth

Convection Current

causes the plates to move

Subduction

an event which the sub of rock thrusts into the mantle

Trench

a depression in the seafloor produced by subduction process

Convergent Boundary

is where the two plates moves towards each other

Divergent Boundary

is where the two plates move apart

Active Volcanoes

that have a history of eruption

Inactive Volcanoes

those who have none, also have a signs of physical change due to weathering and erosion

Potentially Active Volcanoes

are young looking and have no record

Fault

is a fracture or a crack found in the crust, example  of it is the San Andreas Fault in California USA

Normal Faults

have hanging walls that move down relative to the footwall

Hanging Wall

is the block immediately above the fault surface

Footwall

lies below the fault surface

Reverse Fault

or also called Thrusts Fault it occurs when the hanging wall moves up relative to the footwall

Strike Slip Fault

are those where the dominant displacement occurs along the strike of the fault
