Earthquake
Sudden movement of the earth's crust when crustal plates shift.
EARTHQUAKE
Intensity number of: Many buildings are destroyed, bridges are also destroyed.
Intensity VIII (8)
Outer most shell about 80 kilometers thick which is solid and rigid.
Lithosphere
Refers to vent, hill, or mountain from which molten or hot rock or gaseous materials are thrown out
VOLCANO/ES
Some erupitions may form high level areas called what?
- Earthquake cause by sudden movement of rocks underneath.
- Earthquake brought about by rising of magma beneath volcanoes.
- Tectonic Earthquake
- Volcanic Earthquake
What scale in magnitude is this: Felt over wide areas, causes small local damage near the epicenter
Magnitude (M) 5-6
Lithosphere is further divided into small and large pieces called what?!
Tectonic Plates
- How many volcanoes on Land?
- Where and what is the name of the major volcanic belt
- 600 Volcanoes
- Ring of Fire in the rim of Pacific Ocean
What is Active and Inactive Volcano?
- Active Volcano = has erupted with historic times within the last 600 years and documented by a man.
- Inactive Volcano = has not erupted within historic times and it is beginning to be changed by weathering and erosion.
Tectonic Earthquake can occur with these depths, name the kilometers of these following depths of tectonic earthquake.
- Shallow _____
- Intermediate _____
- Deep _____
- Shallow = 0-70 kilometers
- Intermediate = 70-300 kilometers
- Deep = 300-700 kilometers
Who and what type of scientist is the inventor of Magnitude Scale?
Beneath the lithosphere is another shell called what?
Asthenosphere
Differentiate Magma and Lava.
Magma is a molten material that is extremely hot and contains dissolved gases while Lava is the magma that reaches the surface of the earth.
Changes on the Earth's Surface as a result of Volcanic Eruptions
- What changes is repeated lava flows during quiet eruptions gradually build up a broad, gently sloping volcanic mountain.- Shield Volcano
- Cinder Cone
- Composite Volcanoes
because it is closer to the earth's surface where mostly humans live and build houses and buildings.
The date, magnitude, and the epicenter when Luzon was struck by one of the greatest earthquake.
- July 16,1990
- Magnitude of 7.7
- Cabanatuan City in Nueva Ecija
- Crust
- Mantle
- Outer Core
- Inner Core
- Trenches = Converging Plate Boundary
Phreatomagmatic eruption is the eruption resulting ejection of fresh magmatic materials such as ash, volcanic bomb, and steam while Phreatic eruption is explosion driven by steam produced by heating and expansion of groundwater.
Differentiate Focus or Hypocenter with Epicenter.
Focus or Hypocenter is the place where earthquakes originate while Epicenter is the exact point above the focus.
WAIT FOR TEACHER TO DRAW!
Bonus Question:
- What instrument is used for measuring and recording earthquake waves or seismic waves?
- These are the recorded lines.
- CONGRATS?
- Seismograph
- Seismograms
Draw and differentiate the three plate boundaries
Divergent Plate Boundary - 2 neighboring plates moving away from each other or are pulling apart.
Convergent Plate Boundary - 2 neighboring plates move toward each other.
Transform Fault Boundary Vertical surface that cuts and breaks the continuity of the first 2 plate boundaries
Draw and label all of the cross section of a Volcano.
