Invariables
100
What was the name of the man who discovered seafloor spreading?
Harry Hess
100
What are fault zones?
Cracks that occur when plates move past eachother
100
What is the difference between lava and magma?
Magma is underground and hard and lava is above ground and liquidy
100
What is the difference between a silicate and a non-silicate?
A silicate contains silicon and Oxygen but a non-silicate does not
200
At what degree is the Earth's axis tilted on?
23.5
200
Is oceanic or continental crust more dense?
Oceanic
200
What is the Elastic Rebound Theory?
When plates move past each other they begin to bend as stress builds up, then plates move past and the plates rebound back into shape causing an earthquake
200
What are the 3 types of volcanoes? Name and Describe them with a real life example of each
Shield- Wide with low-viscosity lava and is non explosive ex. Kilauea
Cinder Cone- Short and steep with medium-viscosity, medium explosiveness ex. Paricutin
Composite (Stratovolcano)- Very tall and mountainous with high viscosity, very explosive ex. Mt. St. Helens
200
Name the 6 types of igneous rock textures. APPVGF
Aphanitic- Can't be seen
Phaneritic- Large crystals that can be seen
Porphyritic- Some are fine and some are large
Vesicular- Gas bubble rock that are light weight
Glassy- smooth
Fragmental- Ash material with chunks of rock
300
What is the difference between the Outer Core and Inner Core?
The Outer Core is liquidy and the Inner Core is Solid
300
What is the difference between the lithosphere and asthenosphere?
Lithosphere: Rigid crust and upper mantle that sits on top of the asthenosphere. Ashthenosphere: Molten Material below the lithosphere that causes plates to move
300
What is the difference between Primary and Secondary waves?
Primary are faster and are shear waves. Secondary are slower and are compressional waves
300
When was the Mt. St. Helens explosion and how many people were killed? Where is Mt. St. Helens as well?
1980, 57, Washington State
300
What are the 3 textures of sedimentary rocks? CCO
Clastic- Made from smaller rocks or sand
Chemical- Dissolved mineral that harden after water evaporates
Organic- Rock made from once living things
400
When is the Vernal Equinox and where does the sun strike?
March 20, directly on the Equator
400
What causes convection currents and what do they cause?
When heated material in the atmosphere rises and sinks, it causes plates above to move
400
What are surface waves?
Rayleigh Waves and Love Waves cause the surface of Earth to shake and cause damage.
Solid, Inorganic, Occur naturally, orderly crystalline structure, same chemical composition
500
How many steps are in the Scientific Method and what are they?
5, 1.) State the Problem 2.) Gather Information 3.) Form a Hypothesis 4.) Test the Hypothesis 5.) State a conclusion
500
What are divergent and Convergent Continental boundaries?
Divergent: Plates moving away from eachother
Convergent: Collision of continents
500
What is the Hypocenter?
The point underground where the stress is released around the fault and seismic waves are created
500
Name and describe the 7 parts of a volcano.
Ash cloud- Cloud of ash and dust when a composite volcano erupts
Conduit- Tube where magma rises
Crust- Layer of Earth the volcano sits on
Magma Chamber- Where magma is stored
Vent- Opening where lava erupts
Side Vent- Additional opening on the side of a volcano
Volcanic Layers- Hardened layers of lava that make up the volcano
500
