Layers of the earth
True/False the inner core is solid.
True
The crust
What type of volcano is made of ash and cinders and has steep slopes?
Cinder Cone
Which earthquake caused more shaking and damage
Los Angeles- magnitude 7.8
San Francisco- magnitude 5.4
San Jose- magnitude 1.1
Los Angeles
What type of wave move rocks side to side at a right angle to the path of the wave?
S-wave
As you move deeper into the earth, the temperature _________________.
Increases
What type of plate boundary is formed when two plates move together?
Converging Boundary
True/False: Volcanoes with thick, viscous lava that flows slowly lead to smaller, less explosive eruptions
False
Seismographs detect the __________ caused by an earthquake.
Vibrations or shaking
Seismic Waves
Waves
Which seismic wave is the fastest?
P wave
What layer of the earth is the largest (has the most volume).
The Mantle
What type of boundary forms the worlds largest mountains?
converging boundaries
What type of volcano is formed far away from plate boundaries?
Hot Spot volcanoes
What is the name of the force the hold plates together along a fault?
Friction
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 is the difference between a pyroclastic flow and a Lahar?
A pyroclastic flow only contains volcanic materials while a Lahar contains volcanic materials and water.
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.
In class we watched videos showing a diverging boundary between two continents in Iceland. What is the name for the feature that formed in the video
A rift valley
How can a large volcanic eruption lead to global cooling?
sulfur gasses in the atmosphere reflect light from the sun back into space
(Wait for Mr. Burjes to draw) Where is the epicenter of the earthquake according to the 3 seismographs?
C
What is lag time
The time between when a P wave and an S wave arrive at a seismogoraph
