This spot can be located within the Earth or on top of the crust. It is the part of the earth to shake first.
What is an Earthquake's "focus" point.
100
What are the three main types of volcanoes?
What are "Shield, Cinder-Cone, Strato/Composite" volcanoes.
100
This scientists is known for coming up with the theory of "Continental Drift."
Who is "Alfred Wegener"
100
This cycle is known to cause plate tectonics to move because it creates changes in density in the Mantle of the Earth? Which of the Earths 4 layers has the most volume? How much space does it take up?
What is a "convection current" What is Earth's "Mantle" What is "70%"
100
This type of scale is used to measure the intensity of an earthquake? What is intensity?
What is the "Modified Mercalli Scale?" Intensity shows how much damage has be created because of an Earthquake.
200
This is known as the area where Primary and Secondary Waves reach first. It is located directly above the "focus Point" of an earthquake.
What is the "epicenter"
200
This volcanoe is known to shoot Pryro-clasisic flow into the air and also known becuase is has alternating layers of lava and ash that accumulate on the volcano after an explosion.
What is a "Strato/Composite" volcanoe.
200
What is a fault? Why does it occur?
What is "a crack in the earth caused by built up pressure from geologic events"
200
Which of the 4 layers of the earth is the most dense? Explain!
What is the earths "inner core" Because all weight of the crust, mantle, and outter core are pushing down/providing pressure on the inner core.
200
This is a scale that is used to measure an Earthquakes magnitude. What is magnitude?
What is the "Richter Scale" What is "the strength of an earthquake/it's waves"
300
What are the 3 types of Waves associated with Earthquakes? Which causes the most damage?
What are "Primary ( P ), Secondary (s), and Surface Waves. What are "Surface Waves"
300
What is the difference between a "dormant," "active," and "extinct" volcano?
What is Active: Dormant (sleeping): Extinct:
300
What are 3 boundaries that cause plates to move on the Earth's Crust?
What are "Convergent, Divergent, and Transform" boundaries.
300
What is the difference between an inference and an observation?
What is "an observation is when scientists use their 5 senses to gather data" What is "an inference is when observations are analyzed to make a claim"
300
What happens during "convection currents" and where in the Earth do they take place?
What is "mantle material is warmed by the outer core and looses density as it rises to the crust, then gives off energy, gains density, and sinks back down to the bottom of the mantle" What is "Earth's Mantle"
400
Name 2 facts for P, S, and Surface Waves.
Answers will vary
400
These are used to decrease the amount of pressure built up during a volcanic explosion/eruption. Not all volcanoes have them which is why they erupt violently.
What are "side vents"
400
Create a bubble map that shows Convergent and Divergent plate teconic boundaries, and what is formed becuase of them.
What is Convergent boundary: - "buckling zones" form mountains/volcanoes" - "Subduction zones" form trenches" Divergent boundary: - "Rifting zones"forms cracks on the Earths surface. - "Mid-Ocean Ridges" form/create "slab pulls"
400
This object can be seen in the ski because it leaves a tail of debris that can be millions of miles long.
What is a "comet"
400
What is Pangea? How does the theory of "fossil distribution" support the theory of Pangea?
What is " a supercontinent composed of all 7 continents together" What is "fossils of the same creature found on 2 serparate continents proves Pangea once existed."
500
This is used to locate the epicenter of an earthquake. It uses three known points taken from a seismogram to located a 4th unknown point.
What is "triangulation"
500
Draw a picture of the 3 different types of volcanoes and label the following: 1)Summit crater 2)steepness of their sides 3)size 4)type of eruption created.
Shield Volcano: Quiet/non-violent eruption, huge base but small, non-steep sides. Strato/composite: Explosive eruption, small crater, medium sides, very large. Cinder Cone: Explosive eruption, big crater, very steep sides, very small.
500
(DAILY DOUBLE) How do mid-ocean ridges create slab pulls?
What is Mid-ocean ridges create slab pulls divergent boundaries force plates away from each other creating a mid-ocean ridge. The lava pushes old crust away from the ridge and leaves new crust on top. The weight/density of the built up old crust causes that crust to sink/subduct back into the earths mantle.
500
These maps show the elevation of specific points on a landmass on the earth. If a hiker was climbing a mountain and had this map, how would he/she know the steepest point to climb.
What is a "topographic map". What is "closer lines represent steeper inclines."
500
Officials in Chile report surprisingly light damage and a low death toll for such a strong temblor. How would you write this using the words "magnitude" and "intensity"?
What is "an earthquake with a high magnitude and low intensity"
