Vibrations or shaking
Seismic Waves
Waves
Which seismic wave is the fastest?
P wave
What layer of the earth is the largest?
The Mantle
What type of boundary forms the worlds largest mountains?
converging boundaries
What type of volcano is formed far away from plate boundaries?

When you use triangulation, where is the epicenter of the earthquake?
Where all three circles intersect.
What is the name of the point on the surface of the earth that is directly over the focus?
Epicenter
Which layer of the earth is densest?
The inner core
There is a diverging boundary at the center of the Atlantic ocean called the mid Atlantic ridge. Is the boundary causing the Atlantic ocean to become larger or smaller?
Larger
What does water vapor mix with to create acid rain?
sulfur dioxide
The Richter scale measures the amount of energy released during an earthquake. Is it a quantitative or a qualitative measurement?
Quantitative
What type of wave creates a motion similar to an ocean wave
Surface Wave
L-Wave
Why do hot portions of the mantle rise up towards the surface.
The heat makes that matter less dense, and because it is less dense it rises.
What is formed due a diverging boundary on land?
A rift valley
How can a large volcanic eruption lead to volcanic winters?
gases and ashes mix together and block out heat from the sun.
What are the three secondary Hazards of earthquakes?
What is lag time
The time between when a P wave and an S wave arrive at a seismogoraph
