What's the main cause of most earthquakes?
Pressure from within Earth's crust
Hurricanes
Human activity
Changes in temperature within the earth's mantle
Which of the following is a true statement about tectonic plates?
All tectonic plates are located at Earth's core
They're located approximately 10 meters below the surface of the ocean
They're located in the molten layer beneath Earth's crust
All of Earth's landmass rests on tectonic plates
The weight of the lithosphere keeps the mantle in a semi-solid state. What can you infer from this?
Pressure and heat have similar effects on solids
Pressure raises the melting point of solids
Pressure lowers the melting point of solids
Pressure has no effect on the melting point of solids
Place the following in sequence from highest to lowest temperature: A) Lithosphere; B) Mantle; C) Core
C, A, B
B, C, A
C, B, A
A, C, B
What can you infer from the fact that tectonic plates are always moving around?
New volcanoes form every few years.
The shape and location of the continents have changed over time.
Tectonic activity probably caused the last Ice Age.
Earthquakes will continue long after hurricanes and tsunamis have stopped.
Why are surface waves more destructive to buildings than the initial seismic wave in an earthquake?
It creates more sustained motion on the surface.
It reaches the surface faster.
It reaches deeper below the surface.
It travels farther from the hypocenter.
What is this instrument called?
Richter scale
Barometer
Electrograph
Seismograph
Why are faults sometimes referred to as "active boundaries?" Choose the best answer.
Because they are all volcanically active
Because they serve as boundaries between nations
Because Earth's crust shifts on either side of them
Because people must actively avoid faults to escape injury
In the phrase, "The Richter scale measures the potency and duration of seismic events," what does "potency" mean?
Speed
Strength
Type
Time
Which city is most likely to experience a strong earthquake?
Los Angeles
Chicago
New York
Miami
