Mid-ocean ridge edges are destructive, are formed when the lithospheric plates separate and grow the oceans
Pits are destructive edges, are formed when the oceanic lithospheric plate sinks.
Continental crust is 30 to 70 km deep in the continent.
Oceanic crust between 5 and 10 km deep in the oceans
3 large dorsal Pacific, Atlantic and Antarctic Ocean
VOLCANOES: Magma is the materials deeper in the earth's crust, can withstand temperatures of 1000 to 1200 º C and therefore are fused.
Composition of silicate magma (rock fluid) gases and water vapor.
Factors determining the viscosity of magma amount of silica (SiO2) very viscous, slightly fluid
Volcanic materials: solid (volcanic bombs, lapilli and ash), liquid (lava, magma without gas) gas (-emerge gradually, there-explosions within the volcano is piling up, there are explosions)
Types of Volcanoes
Hawaiian: very fluid lava, no explosions, eg Mauna Loa
Strombolian eruption: lava less fluid, eg solid gas explosions stromboli
Vulcan: less fluid lava, violent explosions lipari eg
Fight: very viscous lava, very violent Explosin Mount pete eg martinique

EARTHQUAKES: vibratory movements are short-lived due to fractures in the crust
Causes: discolacociones internal materials of the crust and movements of the layers
Hypocenter (focus) is the internal point of the earth where the earthquake originates
Epicenter: is where the earthquake has more intensity
Seismograph: A device that records the arrival of seismic waves
Seismogram: recording seismic waves
Seismic Waves: originate during the earthquake can be P (faster, originate from the hypocenter) S (are the second, stem from the hypocenter) L (originating at the epicenter, are what cause the damage)
SCALES: The Mercalli me indicating damage Richter and indicates the energy of the earthquake
Weathering: disintegration or chemical alteration of rocks by the action of the atmosphere and living things. TYPES: Physics (if broken) Chemistry (when such changes color)
Biological (when involving the living)
Weathering PHYSICS: Gelifración (rainwater falls between the cracks of rocks) Termosfracion (the rocks of the lower contract and expand with temperature increase) Haloclastia (occurs as the water evaporates which remained in the crevices of the rocks )
Erosion starting and moving material
Transport: the transport of material eroded from one place to another
Sedimentation: the deposit of material transported
