The Earth and its Plates
What is the theory that explains the movement of the Earth's lithosphere (crust)?
The theory of plate tectonics
What is the name for the point on the Earth's surface directly above where an earthquake occurs?
Epicenter
Magma
Hypothesis
Name one of the three types of plate boundaries.
Strike-slip (transform), normal (divergent), reverse (convergent)
What is the machine called that measures earthquakes?
Seismograph
What do we call the opening of a volcano through which lava, ash, and gas escape?
A vent
The first step in the Scientific Process is
Inquiry (question, problem)
What type of plate boundary often causes earthquakes?
Strike-slip (transform)
The Richter scale measures the ___________________ of an earthquake.
Magnitude
_______________ and ________________ types of eruptions are usually not violent or very dangerous.
Hawaiian, Strombolian
In a good experiment, how many variables should you have?
One
Name the four layers of the earth (does not have to be in order).
Crust, mantle, inner core, outer core.
Pacific Ring of Fire
Name the three types of volcanoes when classified by shape.
Shield, composite cone, cinder cone.
______________ is the step of the process where you look closely at the findings from an experiment.
Analysis
In one sentence, describe how plate tectonics can cause mountains.
When two plates move together at a reverse fault line, the crust is forced upward, creating a mountain.
Which type of waves occur second during an earthquake, and are the type that we usually feel?
S waves (secondary waves)
What is the term for a volcano that is no longer active but COULD potentially erupt again?
Dormant
List the 5 steps of the Scientific Process in order.
