SCIENCE 4Q

• tectonic plate ( called as lithospheric plate)
• tectonic plate - massive, irregularly shape slab of a solid rock
• tectonic plate can be composed of both oceanic and continental crust
• if collider grind each other, the amount of energy will be releeased causes the grounded to vibrate
• focus - source or orgin of the earth quake
• epicenter - point on the surface directly above the focus
• types of earthquakes

  1. tectonic earth quake
  2. volcania earth quake
• tectonic earth quake - accur when the plates oof earth move akong breaks or cracks
• breaks or crack on earth crush is called faults
• volcanio earth quake - rising lava or mag a be earth active volcanoes
• most earth quake accur on the pacific ring of fire
• branch of sciences that deals with the study of earth quake seismology
• who study earth quake - seismologist
• what instrument used to detect the accur range of earth quake - seismograph
• what do you call the record or data from the seismograph - seisogram
• magnitude - energy released by an earth quake from its focus
• intensify - degree of shaking
• tsu - harbor
• tidal wave - tsunami
• nami - wave
• oceanic converge t - form trenches nd volcanic arcs
• volcano - opening on earths surface, which molten lava and other bases are produced. it is a cone shaped mountan

  A) ash cloud

  B) fissures

  C) lava

  D) lava and ash

  E) main vent conduit

  F) magma

  G) crater
• crater - funnel-like opening ot mouth of a volcano. it is formed when eplosive eruptions occur at the central vent
• vent - opening on the surface of a volcano
• magma - molten ricks inside a volcano
• lava - it is th magma that reaches the surface or outside of the volcano
• magma chamber - storage of magma inside the volcano
• conduit - where magma passes through like a pipe due to pressure
• classification of volcano

  
• shield volcano - low, side cone, flat top, no crater, erupts slowly
• shield volcano flows out like peanut butter
• composite volcano - the most explosive and dangerous volcano and the largest and tallest
• cinder cone - smaller in size than composite
• lava dome - smaller because of having very high viscosity or thickness
• Active volcanoes have a recent history of eruptions; they are likely to erupt again.
• inactive volcanoes have not erupted for a very long time but may erupt at a future time
