Dark colored igneous rock
What is mafic
100
An example of a volcano's effects on the atmosphere
What is acid rain, ash, blocking sun, etc.
100
These form as the crust around a displaced fault re-adjusts after an earthquake
What is an aftershock
100
Two pieces of evidence that support the Theory of Plate Tectonics
What is coastlines, rock strata, fossils, coal distribution
100
The four spheres
What are the atmosphere, biosphere, lithosphere, atmosphere
200
Coarse grained rock
What is intrusive
200
The density of the magma under a volcano causes it to....
rise to the surface during an eruption
200
The two forms of energy most closely associated with an Earthquake
What is epe and ke
200
Boundary when plates move past each other and crust is not created or destroyed
What is a transform boundary
200
The location on the surface above an Earthquake
What is the epicenter
300
The farther from the epicenter the ________ the gap between the p and s waves
larger
300
The characteristics of the magma determine what about the volcano's eruption?
The explosiveness
300
The magnitude of an earthquake tells us
How strong it is
300
Convection currents occur in this layer of the Earth
What is the mantle.
300
Number of seismograph stations needed to locate an earthquake
What is 3
400
Would you rather build a house on hard bedrock or soft mud to withstand mechanical waves?
Hard bedrock
400
Where are most volcanoes located
By plate boundaries/ring of fire
400
Two examples of a secondary effect of an earth quake
What is tsunami, flood, fire, companies going out of business, etc...
400
What type of plate boundary forms new crust?
At a divergent boundary
400
Describe how a volcano can change the lithosphere and then how these changes could change one of the other spheres
Volcano can create new and fertile land that can have plants grow more easily in more places. This new land could also create new lakes or rivers.
500
S-waves cannot travel through the outer core while p-waves can. Scientists can infer the outer coure is ____
What is a liquid
500
The type of rock made from magma that has cooled
What is igneous
500
The opening & sifting of the ground during the an earthquake
What is a primary effect
500
The cycle of heating, rising, cooling, and sinking that drives plate movement
What is convection current
500
Describe why an earthquake occurs using the words epe, ke, mechanical waves, and energy transformation
epe builds up until rocks break or slip, this energy changes into ke in the form of mechanical waves creating an energy transformation
