Scientific Method
The process used by scientists to find a solution to a problem.
What is the scientific method?
breaks in the earths surface along which rock can move
What are faults?
The point on the earth's surface directly above the focus of an earthquake
what is the epicenter?
magma that breaks through the earths rurface
what is lava?
An activity used to test if your hypothesis is true or false.
Occurs when rocks move horizontally past each other
What is a strike slip fault?
The scale that measures earth's magnitude
the richter scale
an avalanche-like emission of red-hot dust and gases from a volcanic eruption - killed the people of pompeii
what is pyroclastic flow
The three words used in hypothesis statement.
What is if, then, and because?
Occurs when rocks push together, forcing a section of rock upward
What is a thrust or reverse fault?
The machine that detects, times, and measures the movements of the earth
what is a seimograph
when part of a mountain collapses causing mud and rock fragments to surge down the mountain
what is pyroclastic flow
A final statement that describes what you learned from the experiment and results
What is the conclusion?
occurs when rocks move apart forming a gap
What is a normal fault?
what is the focus
caused by a hot spot and heated magma rising to the surface
what is a volcanic eruption
The 5 steps in the scientific method.
What is question, hypothesis, experiment, data, and conclusion?
Vibrations of energy that flow from the focus of an earthquake.
what are seismic waves?
the strength of the seismic waves of an earthquake
what is the magnitude?
volcanic fog
what is fog
