FOLD = deformation in rocks created by stresses which produce bends or curves
Types of folds
According to thedirection of curvature
Anticline
Syncline
According to theangle of theaxial plane
Symmetrical
Inclined
Overturned(tumbado)
Recumbent(acostado)
Overturned fold
Recumbent fold
After erosion happens in an anticline fold the oldest layers appear in the middle

Rocks are always formed form pre-existing rocks that undergo processes of transformation
Types of rocks
Exogenous rocks(external
processes)sedimentary
Endogenous rocks
(internalprocesses)
igneous
metamorphic
caused by solar energy
Weathering rocks break up due to the action of the atmosphere water living thingshellip
Mechanical weathering Chemical weathering Weathering caused byliving beings
Erosion loosened pieces of rock start moving
Transportation eroded material is transported
Sedimentation deposition of materials
Diagenesis sediments are transformed into sedimentary rocks
caused by heat and pressure inside the Earth
GEOTHERMAL GRADIENT = the internal temperature of the Earth increases with dephtabout 30ordmC every kilometre
It causes
Volcanoes
Geysers
Thermalsprings

Friction
Radioactivesubstances

OROGEN = Mountain range also called ldquocordillerardquo
Andean type orogen
An accretionary prism is formed
Accumulated marine sediment on the edge of a continental platethat has been scraped off a subducting oceanic plate
Alps Himalayas Pyrenees
The process of formation is faster thanthe Andean type
The deformation and metamorphism of rocksis greater
Rocky Mountains
Fragments of rocks from the lithosphere are added to the appearing mountain
OROGENY = Geological period in the past when the crust was deformed and foldedtherefore mountain ranges appeared
There has been three important orogenies in the past
1 Caledonian Orogeny 2 HercynianOrogeny
3 Alpine Orogeny
ISOSTASY is the state of equilibrium between the lithosphere and the mantle
If the weight of the lithosphere
increasesIt sinks
If the weight of the lithosphere
decreasesIt rises
What happens whenhellip
hellip a thick layer of sediment is deposited
hellip a thick covering of ice is formed
hellip a mountain range is eroded
hellip the ice of an ice cup melts
The lithosphere sinks The lithosphere rises
The lithosphere sinks The lithosphere rises

OROGEN = Mountain range also called ldquocordillerardquo
Andean type orogen
An accretionary prism is formed
Accumulated marine sediment on the edge of a continental platethat has been scraped off a subducting oceanic plate
Alps Himalayas Pyrenees
The process of formation is faster thanthe Andean type
The deformation and metamorphism of rocksis greater
Rocky Mountains
Fragments of rocks from the lithosphere are added to the appearing mountain
OROGENY = Geological period in the past when the crust was deformed and foldedtherefore mountain ranges appeared
There has been three important orogenies in the past
1 Caledonian Orogeny 2 HercynianOrogeny

3 Alpine Orogeny
ISOSTASY is the state of equilibrium between the lithosphere and the mantle
If the weight of the lithosphere
increasesIt sinks
If the weight of the lithosphere
decreasesIt rises
What happens whenhellip
hellip a thick layer of sediment is deposited
hellip a thick covering of ice is formed
hellip a mountain range is eroded
hellip the ice of an ice cup melts
The lithosphere sinks The lithosphere rises
The lithosphere sinks The lithosphere rises

Locations
Rifts
(California)
Subduction zones with high risk of
tsunamis
(Chile Japan Indonesia)
Continental collision zones
(Himalayas Pyrenees)
The danger depends on
The viscosity of the magma
The contents in gases
Types of eruptions
HawaiianLow viscosity magma flows very quickly
Vulcanian
Intermediate viscosity
Lava flows and pyroclasts
Plinian
High viscosity and high gas
