Boundary where plates move towards each other

Convergent boundary

Responsible for creating mountain belts and ranges

Convergent boundary

is a massive piece of thick and hardened stratified rock that floats above the liquid earth it sits upon.

Plate

are responsible for their formation.

Plate tectonics

It was then widely accepted by the scientific community when the continental drift theory was supported by the evidence of seafloo spreading in the 1950s to 1960s.

Plate tectonics

are plates that meet at a certain point and collide with one another.

Convergent plates

True or false: Trenches are the most common points of divergent plates.

True

are plates that dirft away from a common point.

Divergent plates

are plates that slide past one another, neither creating nor destroying one another.

Transform plate

True or false: The San Andreas Fault is an example of a dextral fault.

True

The motion can be observed at the left (called a ___) or at the right (called a ___).

Sinistral fault, dextral fault

fracture that stretches from the boundary

Normal fault

Fracture meeting at certain point

Reverse fault

THIS IS the crust that HOIDS the continents. It is less dense than the other type.

Continental drift

Happen below the ocean

Mid-oceanic drift / ridge

Fracture or crack that is being release wides the ocean deep sea vent

Slip

Gravitational force of fracture of one's plate

Joint

Bending of the rocks or deformation

Fold

The Theory states that earth's CRUST IS DIVIDED into several. Plates that Gildes over the mantie, acting as HARD SHell.

Plate tectonics

It IS DIVIDED INTO TWO DISTINCT SUBSPHERES : LITHOSPHERE & asthenosphere

Continental drift

How did the continent form

Pangea ( 7 continents)

Another continent that is being experiment

Ice island

__ creates tremendous stress near plate boundaries; this stress deforms rocks

Tectonic movement

A ___ is any feature produced by rock deformation

geologic structure

When deformation is brittle, rocks break, it forming ___

joints or faults.

When deformation is ductile, rocks bend without breaking, it forming __

Folds

one arching downward is a ___ .

syncline

A fold arching upward is an __

anticline

The sides of a fold are called the __ .

limbs

anticlines do not necessarily form ___ .

topographic ridges

__ are most commonly caused by compressive stress.

Anticlines

are created by combinations of tectonic and surface processes

Landforms

synclines do not form __

valleys

Synclines are like __-they are U-shaped folds in which strata dip towards the fold axis and the strata become younger as one moves towards the fold axis. A

basins

A __ resembles an inverted cereal bowl

dome

A circular or elliptical anticlinal structure is called a __

dome

A similarly shaped syncline is called a __ .

basin

A __ is an open, step-like structure in which the layers are all inclined in the same direction on either side of the fold axis.

monocline

__ (perfectly shaped) are rare in nature.

Cylindrical anticlines

is a fracture along which rock on one side moved relative to rock on the other side.

Fault

is the distance that rocks on opposite sides of fault have moved

Slip

form most often due to compression-forces that push rock together, breaking the rock and creating a fault.

Reverse fault

is a special type of reverse fault that is nearly horizontal.

Thrust fault

are typically nearly vertical and move rock horizontally past each other on either side of the fault.

Strike - slip faults

__ arise due to shear stress- forces moving past one another

Strike-slip faults

When the side across the fault moves to the right, it is called a __. If the side across the fault moves to the left, it is a __ .

right-lateral strike-slip fault, left-lateral strike-slip fault

is a fracture in which rocks on either side of the fracture have not moved

Joint

__ are important in engineering, mining, and quarrying because they are planes of weakness in otherwise strong rock.

Joints and faults

As they mapped the sea floor, oceanographers discovered the largest mountain chain on Earth, now called the ___

Mid- Oceanic Ridge system.

Which are the oldest rocks?

at the far left and far right of the Mid-Atlantic Ridge

Which are the youngest rocks?

in the middle of Mid-Atlantic Ridge

proposed an explanation for these odd magnetic patterns on the sea floor

Frederick Vine. Drummond Matthews, and Lawrence Morley

to mapping the topography of the sea floor, oceanographers towed devices called

magnetometers

oceanic crust is composed mostly of __, an igneous rock rich in iron.

basalt

refers to the upward and downward flow of fluid material in response to heating and cooling

Convection

is the upper portion of a convecting cell and thus glides over the asthenosphere as a result of the convection

Tectonic plate

contains the brittle materials that make it ngid It is composed of the crust and the upper mantle, whose molten peridotite composition allows it to resist flow.

Lithosphere

is the layer that contains all the liquid and semi-liquid rocks, which can be found in the mantie

Asthenosphere

This is the region on the lithosphere where tectonic plates are moving relative to each other

Plate boundary

This is the plate boundary where seafloor expansion occurs.

Divergent boundary

This is the plate boundary where plates collapse and volcanic arcs are made.

Convergent boundary

Kapag active yung subduction tinatawag itong

Subduction zone

the denser oceanic plate subducts to the less dense oceanic plate, creating island arcs

Ocean-ocean plate convergence

the oceanic plate automatically subducts, creating continental volcanic arcs.

Ocean-continent convergence

the less dense continental plate rises above, the denser continental plate, creating collision mountain beita in the process.

Continent - continent convergence

It is any factor that drives tectonic plates to move.

Plate movement

The thermodynamic heating of the liquid rocks in the mantle provides movement to the plates.

Mantle convection

This is the tensional force exerted by cold, dense oceanic plates as it subducts into the mantle due to its weight. This works in conjunction with the mantle convection.

Slab pull

Also known as gravitational sliding, it is a proposed driving force that occurs at mid-ocean ridges as the result of the lithosphere sliding down the asthenosphere

Ridge push

This is a theory proposed by John Tuzo Wilson, who tried to correlate plate movement with the Earth's timeline.

The wilson cycle

Exogenic and endogenic processes weather down mountains, which allows the crust to restart the entire cycle.

Orogenesis

As continental plates proceed to collide, crustal roots are formed and build mountains

Continental collision

Fragments carried by the subducting plate accretes and welds materials to the continent

Subduction welding

Oceanic crust subducts beneath a continental crust, creating a volcanic mountain belt at at the active margin

Volcanic mountain belt formation

As the spreading continues, passive margin cooling occurs and sediments accumulate

Passive margin cooling and sedimentation

New ocean basin and new oceanic crust are created.

Ocean basin and crust development

Continents split due to rifting.

Continent rifting
